106-647: Darwin Mounds is a large field of undersea sand mounds situated off the north west coast of Scotland that were first discovered in May 1998. They provide a unique habitat for ancient deep water coral reefs and were found using remote sensing techniques during surveys funded by the oil industry and steered by the joint industry and United Kingdom government group the Atlantic Frontier Environment Network (AFEN) (Masson and Jacobs 1998). The mounds were named after

212-941: A referendum on devolution proposals in 1997 , the Scotland Act 1998 was passed by the British Parliament, which established a devolved Scottish Parliament and Scottish Government with responsibility for most laws specific to Scotland. The Scottish Parliament was reconvened in Edinburgh on 4 July 1999. The first to hold the office of first minister of Scotland was Donald Dewar , who served until his sudden death in 2000. The Scottish Parliament Building at Holyrood opened in October 2004 after lengthy construction delays and running over budget. The Scottish Parliament's form of proportional representation (the additional member system ) resulted in no one party having an overall majority for

318-403: A "tow fish" and pulled by a tow cable. Up until the mid-1980s, commercial side scan images were produced on paper records. The early paper records were produced with a sweeping plotter that burned the image into a scrolling paper record. Later plotters allowed for the simultaneous plotting of position and ship motion information onto the paper record. In the late 1980s, commercial systems using

424-630: A conical-beam 12 kHz side-scan sonar to find the sunken Vineyard Lightship in Buzzards Bay, Massachusetts. A team led by Martin Klein at Edgerton, Germeshausen & Grier (later E.G. & G., Inc.) developed the first successful towed, dual-channel commercial side-scan sonar system from 1963 to 1966. Martin Klein is generally considered to be the "father" of commercial side-scan sonar. In 1967, Edgerton used Klein's sonar to help Alexander McKee find Henry VIII's flagship Mary Rose . That same year Klein used

530-612: A distinctive Norse–Gaelic culture that saw many Old Norse loanwords enter the Scottish Gaelic spoken by islanders, and through successive generations the Norse would become almost completely assimilated into Gaelic culture and the Scottish clan system. After the conflict, Scotland had to affirm Norwegian sovereignty of the Northern Isles , but they were later integrated into Scotland in

636-569: A full legal union be sought instead, a proposal to which the Scots Parliament would not assent, causing the king to withdraw the plan. Except for a short period under the Protectorate , Scotland remained a separate state in the 17th century, but there was considerable conflict between the crown and the Covenanters over the form of church government . The military was strengthened, allowing

742-409: A glimpse of the shallow structure of the seabed. Side-scan sonar is also used for fisheries research, dredging operations and environmental studies. It also has military applications including mine detection. Side-scan uses a sonar device that emits conical or fan-shaped pulses down toward the seafloor across a wide angle perpendicular to the path of the sensor through the water, which may be towed from

848-530: A group of raiders adopting a name from an Indo-European root , * skot , citing the parallel in Greek skotos ( σκότος ), meaning "darkness, gloom". The Late Latin word Scotia ("land of the Gaels") was initially used to refer to Ireland, and likewise in early Old English Scotland was used for Ireland. By the 11th century at the latest, Scotia was being used to refer to (Gaelic-speaking) Scotland north of

954-578: A letter addressed to Adolf Hitler that detailed his intentions to open peace negotiations with the British. Pintsch delivered the letter to Hitler at the Berghof around noon on 11 May. Albert Speer later said Hitler described Hess's departure as one of the worst personal blows of his life, as he considered it a personal betrayal. Hitler worried that his allies, Italy and Japan, would perceive Hess's act as an attempt by Hitler to secretly open peace negotiations with

1060-634: A lost Russian submarine, at the Westinghouse facility in Annapolis up through the 1990s. This group also produced the first and only working Angle Look Sonar that could trace objects while looking under the vehicle. The first commercial side-scan system was the Kelvin Hughes "Transit Sonar", a converted echo-sounder with a single-channel, pole-mounted, fan-beam transducer introduced around 1960. In 1963 Dr. Harold Edgerton, Edward Curley, and John Yules used

1166-402: A number of Scottish-born authors achieved international reputations, such as Robert Louis Stevenson , Arthur Conan Doyle , J. M. Barrie and George MacDonald . Scotland also played a major part in the development of art and architecture. The Glasgow School , which developed in the late 19th century, and flourished in the early 20th century, produced a distinctive blend of influences including

1272-460: A population of 4.8 million in 1911, Scotland sent over half a million men to the war, of whom over a quarter died in combat or from disease, and 150,000 were seriously wounded. Field Marshal Sir Douglas Haig was Britain's commander on the Western Front. The war saw the emergence of a radical movement called " Red Clydeside " led by militant trades unionists. Formerly a Liberal stronghold,

1378-404: A single conical-beam transducer . Next, units were made with two transducers to cover both sides. The transducers were either contained in one hull-mounted package or with two packages on either side of the vessel. Next the transducers evolved to fan-shaped beams to produce a better "sonogram" or sonar image. In order to get closer to the bottom in deep water the side-scan transducers were placed in

1484-554: A surface vessel or submarine (called a “towfish”), or mounted on the ship's hull . The intensity of the acoustic reflections from the seafloor of this fan-shaped beam is recorded in a series of cross-track slices. When stitched together along the direction of motion, these slices form an image of the sea bottom within the swath (coverage width) of the beam. The sound frequencies used in side-scan sonar usually range from 100 to 500 kHz ; higher frequencies yield better resolution but less range. The earliest side-scan sonars used

1590-620: A visual representation of the underwater environment. One of the inventors of side-scan sonar was German scientist, Dr. Julius Hagemann , who was brought to the US after World War II and worked at the US Navy Mine Defense Laboratory, Panama City, FL from 1947 until his death in 1964. His work is documented in US Patent 4,197,591 which was first disclosed in Aug 1958, but remained classified by

1696-673: Is 30,977 square miles (80,231 km ) with a land area of 30,078 square miles (77,901 km ), comparable to the size of the Czech Republic . Scotland's only land border is with England, and runs for 96 miles (154 km) between the basin of the River Tweed on the east coast and the Solway Firth in the west. The Atlantic Ocean borders the west coast and the North Sea is to the east. The island of Ireland lies only 13 miles (21 km) from

1802-533: Is able to provide an understanding of the differences in material and texture type of the seabed. Side-scan sonar imagery is also a commonly used tool to detect debris items and other obstructions on the seafloor that may be hazardous to shipping or to seafloor installations by the oil and gas industry. In addition, the status of pipelines and cables on the seafloor can be investigated using side-scan sonar. Side-scan data are frequently acquired along with bathymetric soundings and sub-bottom profiler data, thus providing

1908-650: Is broadly divided into three regions: the Highlands , a mountainous region in the north and north-west; the Lowlands , a flatter plain across the centre of the country; and the Southern Uplands , a hilly region along the southern border. The Highlands are the most mountainous region of the British Isles and contain its highest peak, Ben Nevis , at 4,413 feet (1,345 m). The region also contains many lakes, called lochs ;

2014-643: Is demonstrated by sites such as the Callanish Stones on Lewis and the Maes Howe on Orkney , which were built in the third millennium BC. The first written reference to Scotland was in 320 BC by Greek sailor Pytheas , who called the northern tip of Britain "Orcas", the source of the name of the Orkney islands. Most of modern Scotland was not incorporated into the Roman Empire , and Roman control over parts of

2120-609: Is echoed in the place names of Dunkeld , Rohallion , and Schiehallion . The Great Conspiracy constituted a seemingly coordinated invasion against Roman rule in Britain in the later 4th century, which included the participation of the Gaelic Scoti and the Caledonians, who were then known as Picts by the Romans. This was defeated by the comes Theodosius ; but Roman military government

2226-672: Is said to have invested in the Darien scheme . After another proposal from the English House of Lords was rejected in 1695, and a further Lords motion was voted down in the House of Commons in 1700, the Parliament of Scotland again rejected union in 1702. The failure of the Darien Scheme bankrupted the landowners who had invested, though not the burghs. Nevertheless, the nobles' bankruptcy, along with

2332-525: Is typical of the north-west of Europe, although several of the larger mammals such as the lynx, brown bear, wolf, elk and walrus were hunted to extinction in historic times. There are important populations of seals and internationally significant nesting grounds for a variety of seabirds such as gannets . The golden eagle is something of a national icon. On the high mountain tops, species including ptarmigan , mountain hare and stoat can be seen in their white colour phase during winter months. Remnants of

2438-727: The Bruce dynasty and their long-term rivals of the House of Comyn and House of Balliol lasted until the middle of the 14th century. Although the Bruce faction was successful, David II's lack of an heir allowed his half-nephew Robert II , the Lord High Steward of Scotland , to come to the throne and establish the House of Stewart . The Stewarts ruled Scotland for the remainder of the Middle Ages . The country they ruled experienced greater prosperity from

2544-586: The Caledonians and the Maeatae . Other ancient authors used the adjective "Caledonian" to mean anywhere in northern or inland Britain, often mentioning the region's people and animals, its cold climate, its pearls, and a noteworthy region of wooded hills ( Latin : saltus ) which the 2nd century AD Roman philosopher Ptolemy , in his Geography , described as being south-west of the Beauly Firth . The name Caledonia

2650-672: The Celtic Revival the Arts and Crafts movement , and Japonism , which found favour throughout the modern art world of continental Europe and helped define the Art Nouveau style. Proponents included architect and artist Charles Rennie Mackintosh . Scotland played a major role in the British effort in the First World War . It especially provided manpower, ships, machinery, fish and money. With

2756-570: The Community Charge (widely known as the Poll Tax) one year before the rest of Great Britain, contributed to a growing movement for Scottish control over domestic affairs. On 21 December 1988, Pan Am Flight 103 exploded mid–air over the town of Lockerbie , killing all on board as well as eleven Lockerbie residents. It remains the deadliest terrorist attack in the United Kingdom . Following

2862-580: The Hebrides , which had been ruled by various Scottish clans following the death of Somerled in 1164. In 1266, Scotland fought the short but consequential Scottish-Norwegian War which saw the reclamation of the Hebrides after the strong defeat of King Haakon IV and his forces at the Battle of Largs . Up until that point, the Hebrides had been under Norwegian Viking control for roughly 400 years and had developed

2968-625: The Highland Boundary Fault , which runs from Arran to Stonehaven . This part of Scotland largely comprises ancient rocks from the Cambrian and Precambrian , which were uplifted during the later Caledonian orogeny . It is interspersed with igneous intrusions of a more recent age, remnants of which formed mountain massifs such as the Cairngorms and Skye Cuillins . In north-eastern mainland Scotland weathering of rock that occurred before

3074-516: The House of Hanover from the British throne. The threat of the Jacobite movement to the United Kingdom and its monarchs effectively ended at the Battle of Culloden , Great Britain's last pitched battle . The passing of the Treaty of Union did not bring about immediate economic prosperity to Scotland as was widely speculated by the pamphleteer as a result of the little consideration given to prospects of

3180-553: The House of Stuart was resumed with the Restoration in Scotland in 1660. The Parliament of Scotland sought a commercial union with England in 1664; the proposal was rejected in 1668. In 1670 the Parliament of England rejected a proposed political union with Scotland. English proposals along the same lines were abandoned in 1674 and in 1685. The Scots Parliament rejected proposals for a political union with England in 1689. Jacobitism ,

3286-476: The Irish Sea to the south. The population in 2022 was 5,439,842. Edinburgh is the capital and Glasgow is the largest of the cities of Scotland . The Kingdom of Scotland emerged as an independent sovereign state in the 9th century. In 1603, James VI succeeded to the thrones of England and Ireland , forming a personal union of the three kingdoms . On 1 May 1707, Scotland and England combined to create

3392-687: The Last Ice Age has shaped much of the landscape. A significant exception to the above are the fossil-bearing beds of Old Red Sandstones found principally along the Moray Firth coast. The Highlands are generally mountainous and the highest elevations in the British Isles are found here. Scotland has over 790 islands divided into four main groups: Shetland , Orkney , and the Inner Hebrides and Outer Hebrides . There are numerous bodies of freshwater including Loch Lomond and Loch Ness . Some parts of

3498-464: The Mesolithic period . It is believed the first post-glacial groups of hunter-gatherers arrived in Scotland around 12,800 years ago, as the ice sheet retreated after the last glaciation . At the time, Scotland was covered in forests, had more bog-land, and the main form of transport was by water. These settlers began building the first known permanent houses on Scottish soil around 9,500 years ago, and

3604-793: The Moscow region in Russia , and the Kamchatka Peninsula on the opposite side of Eurasia . Temperatures are generally lower than in the rest of the UK, with the temperature of −27.2 °C (−17.0 °F) recorded at Braemar in the Grampian Mountains , on 11 February 1895, the coldest ever recorded anywhere in the UK. Winter maxima average 6 °C (43 °F) in the Lowlands, with summer maxima averaging 18 °C (64 °F). The highest temperature recorded

3710-527: The Parliament of Great Britain , which succeeded both the Parliament of Scotland and the Parliament of England , which rejected proposals from the Parliament of Ireland that the third kingdom be incorporated in the union. Andrew Fletcher , a prominent Scottish patriot, argued that the ratification of the treaty would see Scotland "more like a conquered province", and by 1713, the former Lord Chancellor of Scotland , James Ogilvy, 4th Earl of Findlater , who

3816-632: The River Forth , alongside Albania or Albany , both derived from the Gaelic Alba . The use of the words Scots and Scotland to encompass all of what is now Scotland became common in the Late Middle Ages . Prehistoric Scotland , before the arrival of the Roman Empire , was culturally divergent. Repeated glaciations, which covered the entire land mass of modern Scotland, destroyed any traces of human habitation that may have existed before

3922-683: The River Tay , flows for a distance of 117 miles (188 km). The whole of Scotland was covered by ice sheets during the Pleistocene ice ages and the landscape is much affected by glaciation. From a geological perspective, the country has three main sub-divisions: the Highlands and Islands, the Central Lowlands, and the Southern Uplands. The Highlands and Islands lie to the north and west of

4028-636: The Roman army in the Severan campaign were placed near those established by Agricola and were clustered at the mouths of the glens in the Highlands, the Caledonians were again in revolt in 210–211 and these were overrun. To the Roman historians Tacitus and Cassius Dio , the Scottish Highlands and the area north of the River Forth was called Caledonia . According to Cassius Dio, the inhabitants of Caledonia were

4134-681: The Scots Confession , which signalled the Scottish Reformation 's sharp break from papal authority and Roman Catholic teaching. The Catholic Mary, Queen of Scots, was forced to abdicate in 1567 . In 1603, James VI, King of Scots inherited the thrones of the Kingdom of England and the Kingdom of Ireland in the Union of the Crowns , and moved to London. This was a personal union as despite having

4240-441: The Wars of Scottish Independence , until Robert the Bruce was crowned king of Scotland in 1306. Victory at the Battle of Bannockburn in 1314 proved the Scots had regained control of their kingdom. In 1320 the world's first documented declaration of independence, the Declaration of Arbroath , won the support of Pope John XXII , leading to the legal recognition of Scottish sovereignty by the English Crown. A civil war between

4346-428: The beaver and wild boar . Today, much of the remaining native Caledonian Forest lies within the Cairngorms National Park and remnants of the forest remain at 84 locations across Scotland. On the west coast, remnants of ancient Celtic Rainforest remain, particularly on the Taynish peninsula in Argyll , these forests are particularly rare due to high rates of deforestation throughout Scottish history. The flora of

4452-421: The orange roughy . On 23 October 2001, UK Minister Margaret Beckett made a commitment at WWF's Oceans Recovery Summit in Edinburgh to protect the Darwin Mounds. The summit launched the Edinburgh Declaration, targeting politicians and marine stakeholders alike to sign up to action to safeguard the seas. Deep water bottom trawling had been occurring in the area, with nets as heavy as one tonne dragged across

4558-565: The research vessel , itself named for the eminent naturalist and evolutionary theorist Charles Darwin . The mounds are about 1,000 metres (3,300 ft) below the surface of the North Atlantic ocean , approximately 100 nautical miles (190 km) north-west of Cape Wrath , the north-west tip of mainland Scotland. There are hundreds of mounds in the field, which in total cover approximately 100 square kilometres (39 sq mi). Individual mounds are typically circular, up to 5 metres (16 ft) high and 100 metres (330 ft) wide. Most of

4664-593: The xenophyophore Syringammina fragilissima . This is a giant single-celled organism (a protozoan ) that is widespread in deep waters, but occurs in particularly high densities on the mounds and the tails. Individual xenophyophores can grow to be larger than 20 centimetres (7.9 in) and are often very fragile. The corals themselves provide a habitat for a wide diversity of other marine life including sponges , worms , crustaceans and molluscs . Among these starfish , sea urchins and crabs . Various fish have been observed, including blue ling, roundnose grenadier, and

4770-471: The 14th century is now a crown dependency outside of the United Kingdom; the island groups Orkney and Shetland , which were acquired from Norway in 1472; and Berwick-upon-Tweed , lost to England in 1482 The geographical centre of Scotland lies a few miles from the village of Newtonmore in Badenoch . Rising to 4,413 feet (1,345 m) above sea level, Scotland's highest point is the summit of Ben Nevis , in Lochaber , while Scotland's longest river,

4876-401: The 15th century. Scandinavian culture in the form of the Norn language survived for a lot longer than in the Hebrides, and would strongly influence the local Scots dialect on Shetland and Orkney . Later, a system of feudalism was consolidated, with both Anglo-Norman incomers and native Gaelic chieftains being granted land in exchange for serving the king. The relationship with England

4982-532: The 1870s, and the Fortingall Yew may be 5,000 years old and is probably the oldest living thing in Europe. Although the number of native vascular plants is low by world standards, Scotland's substantial bryophyte flora is of global importance. Side-scan sonar Side scan sonar is used to image large areas of the seafloor quickly. Applications include surveys for marine archaeology , shipwreck hunting, search and recovery (SAR) , and environmental monitoring . In conjunction with seafloor samples, it

5088-415: The 1st century have been found as far north as the Moray Firth . By the reign of the Roman emperor Trajan ( r.  98–117 ), Roman control had lapsed to Britain south of a line between the River Tyne and the Solway Firth . Along this line, Trajan's successor Hadrian ( r.  117–138 ) erected Hadrian's Wall in northern England and the Limes Britannicus became the northern border of

5194-493: The British. After 1945, Scotland's economic situation worsened due to overseas competition, inefficient industry, and industrial disputes. Only in recent decades has the country enjoyed something of a cultural and economic renaissance. Economic factors contributing to this recovery included a resurgent financial services industry, electronics manufacturing , (see Silicon Glen ), and the North Sea oil and gas industry. The introduction in 1989 by Margaret Thatcher's government of

5300-402: The Pictish language went extinct as its speakers shifted to Gaelic. From a base in eastern Scotland north of the River Forth and south of the River Spey , the kingdom expanded first southwards, into the former Northumbrian lands, and northwards into Moray . Around the turn of the millennium, there was a centralization in agricultural lands and the first towns began to be established. In

5406-458: The Roman Empire. The Roman influence on the southern part of the country was considerable, and they introduced Christianity to Scotland. The Antonine Wall was built from 142 at the order of Hadrian's successor Antoninus Pius ( r.  138–161 ), defending the Roman part of Scotland from the unadministered part of the island, north of a line between the Firth of Clyde and the Firth of Forth . The Roman invasion of Caledonia 208–210

5512-405: The Scottish Enlightenment is traditionally considered to have concluded toward the end of the 18th century, disproportionately large Scottish contributions to British science and letters continued for another 50 years or more, thanks to such figures as the physicists James Clerk Maxwell and Lord Kelvin , and the engineers and inventors James Watt and William Murdoch , whose work was critical to

5618-423: The Scottish Parliament after the referendum, following cross-party talks in the Smith Commission . Since the 2014 referendum, events such as the UK leaving the European Union, despite a majority of voters in Scotland voting to remain a member, have led to calls for a second independence referendum . In 2022, the Lord Advocate Dorothy Bain argued the case for the Scottish Government to hold another referendum on

5724-401: The Scottish economy. Campaigners for the union between Scotland and England believed that there would be economic advantages to Scotland as a result of the failed Darien scheme which left the Kingdom of Scotland bankrupt. Eventually however, with trade tariffs with England abolished, trade blossomed, especially with Colonial America . The clippers belonging to the Glasgow Tobacco Lords were

5830-494: The Southern Uplands is Merrick with an elevation of 843 m (2,766 ft). The Southern Uplands is home to Scotland's highest village, Wanlockhead (430 m or 1,411 ft above sea level). The climate of most of Scotland is temperate and oceanic , and tends to be very changeable. As it is warmed by the Gulf Stream from the Atlantic, it has much milder winters (but cooler, wetter summers) than areas on similar latitudes, such as Labrador , southern Scandinavia ,

5936-429: The US Navy until it was finally issued in 1980. Experimental side-scan sonar systems were made during the 1950s in laboratories including Scripps Institution of Oceanography and Hudson Laboratories and by Dr. Harold Edgerton at MIT. Military side-scan sonars were made in the 1950s by Westinghouse. Advanced systems were later developed and built for special military purposes, such as to find H-Bombs lost at sea or to find

6042-451: The area fluctuated over a rather short period. The first Roman incursion into Scotland was in 79 AD, when Agricola invaded Scotland; he defeated a Caledonian army at the Battle of Mons Graupius in 83 AD. After the Roman victory, Roman forts were briefly set along the Gask Ridge close to the Highland line , but by three years after the battle, the Roman armies had withdrawn to the Southern Uplands . Remains of Roman forts established in

It contains nearly one-third of the United Kingdom's land area, consisting of

6254-442: The army and navy, trade, economics, colonial enterprises and other areas across the nascent British Empire . Historian Neil Davidson notes "after 1746 there was an entirely new level of participation by Scots in political life, particularly outside Scotland." Davidson also states "far from being 'peripheral' to the British economy, Scotland – or more precisely, the Lowlands – lay at its core." The Scottish Reform Act 1832 increased

6360-508: The central belt of the country. Perhaps the most significant air raid in Scotland was the Clydebank Blitz of March 1941, which intended to destroy naval shipbuilding in the area. 528 people were killed and 4,000 homes totally destroyed. Perhaps Scotland's most unusual wartime episode occurred in 1941 when Rudolf Hess flew to Renfrewshire, possibly intending to broker a peace deal through the Duke of Hamilton . Before his departure from Germany, Hess had given his adjutant, Karlheinz Pintsch ,

6466-399: The coastline consist of machair , a low-lying dune pasture land. The Central Lowlands is a rift valley mainly comprising Paleozoic formations. Many of these sediments have economic significance for it is here that the coal and iron-bearing rocks that fuelled Scotland's industrial revolution are found. This area has also experienced intense volcanism, Arthur's Seat in Edinburgh being

The UK's tallest tree is a grand fir planted beside Loch Fyne , Argyll in

6678-462: The end of the 14th century through the Scottish Renaissance to the Reformation , despite the effects of the Black Death in 1349 and increasing division between Highlands and Lowlands . Multiple truces reduced warfare on the southern border. The Treaty of Perpetual Peace was signed in 1502 by James IV of Scotland and Henry VII of England . James married Henry's daughter, Margaret Tudor . James invaded England in support of France under

6784-497: The execution of the Scottish king at Whitehall in 1649, amid the Wars of the Three Kingdoms and its events in Scotland , Oliver Cromwell , the victorious Lord Protector , imposed the British Isles' first written constitution – the Instrument of Government – on Scotland in 1652 as part of the republican Commonwealth of England, Scotland, and Ireland . The Protectorate Parliament was the first Westminster parliament to include representatives nominally from Scotland. The monarchy of

6890-426: The family unit and had sharp divisions in wealth, although the vast majority were poor and worked full-time in subsistence agriculture . The Picts kept slaves (mostly captured in war) through the ninth century. Gaelic influence over Pictland and Northumbria was facilitated by the large number of Gaelic-speaking clerics working as missionaries. Operating in the sixth century on the island of Iona , Saint Columba

6996-512: The fastest ships on the route to Virginia . Until the American War of Independence in 1776, Glasgow was the world's premier tobacco port, dominating world trade. The disparity between the wealth of the merchant classes of the Scottish Lowlands and the ancient clans of the Scottish Highlands grew, amplifying centuries of division. In the Highlands, clan chiefs gradually started to think of themselves more as commercial landlords than leaders of their people. These social and economic changes included

7102-400: The first commercial side-scan sonar training videos and the first Side Scan Sonar Training Manual and two oceanographers found the wreck of the RMS Titanic . For surveying large areas, the GLORIA sidescan sonar was developed by Marconi Underwater Systems and the Institute of Oceanographic Sciences (IOS) for NERC . GLORIA stands for Geological Long Range Inclined Asdic . It was used by

7208-475: The first phase of the Highland Clearances and, ultimately, the demise of clanship. The Scottish Enlightenment and the Industrial Revolution turned Scotland into an intellectual, commercial and industrial powerhouse — so much so Voltaire said "We look to Scotland for all our ideas of civilisation." With the demise of Jacobitism and the advent of the Union, thousands of Scots, mainly Lowlanders, took up numerous positions of power in politics, civil service,

7314-507: The first three Scottish parliament elections. The pro- independence Scottish National Party led by Alex Salmond achieved an overall majority in the 2011 election , winning 69 of the 129 seats available. The success of the SNP in achieving a majority in the Scottish Parliament paved the way for the September 2014 referendum on Scottish independence . The majority voted against the proposition, with 55% voting no to independence. More powers, particularly concerning taxation, were devolved to

7420-403: The first villages around 6,000 years ago. The well-preserved village of Skara Brae on the mainland of Orkney dates from this period. Neolithic habitation, burial, and ritual sites are particularly common and well preserved in the Northern Isles and Western Isles , where a lack of trees led to most structures being built of local stone. Evidence of sophisticated pre-Christian belief systems

7526-481: The fluid bubbles up through the sand, pushing the sediment up into a cone shape. Sand volcanoes are common in the Devonian fossil record in UK, and in seismically active areas of the planet. In this case, tectonic activity is unlikely; some form of slumping on the south-west side of the undersea (Wyville-Thomson) Ridge being a more likely cause. The tops of the mounds have living stands of Lophelia and blocky rubble (interpreted as coral debris). The mounds provide one of

7632-414: The imposition of royal authority on the western Highland clans. The 1609 Statutes of Iona compelled the cultural integration of Hebridean clan leaders. In 1641 and again in 1643, the Parliament of Scotland unsuccessfully sought a union with England which was "federative" and not "incorporating", in which Scotland would retain a separate parliament.

Following the Supreme Court decision, the Scottish Government stated that it wished to make amendments to the Scotland Act 1998 that would allow a referendum to be held in 2023. The mainland of Scotland comprises the northern third of the land mass of the island of Great Britain, which lies off the northwest coast of Continental Europe . The total area

7950-548: The largest known northerly cold-water habitats for coral species. The mounds are also unusual in that Lophelia pertusa , a cold water coral, appears to be growing on sand rather than a hard substratum. Prior to research on the mounds in 2000, it was thought that Lophelia required a hard substratum for attachment. The deep-water coral systems on the mounds are especially fragile. Unlike shallow-water coral reefs , they are not adapted to cope with minor disturbances such as wave action. The mounds also support significant populations of

8056-465: The most widely spoken languages in the country , existing on a dialect continuum with each other. Scottish Gaelic speakers can be found all over Scotland, however the language is largely spoken natively by communities within the Hebrides . The number of Gaelic speakers numbers less than 2% of the total population, though state-sponsored revitalisation attempts have led to a growing community of second language speakers. The mainland of Scotland

8162-508: The mounds are also distinguished by the presence of an additional feature referred to as a 'tail'. The tails are of a variable extent and may merge with others, but are generally a teardrop shape and are orientated south-west of the mound. The mound-tail feature of the Darwin Mounds is apparently unique globally. The mounds are mostly sand, currently interpreted as " sand volcanoes ". These features are caused when fluidised sand "de-waters" and

9010-573: The remnant of a once much larger volcano. This area is relatively low-lying, although even here hills such as the Ochils and Campsie Fells are rarely far from view. The Southern Uplands is a range of hills almost 125 miles (200 km) long, interspersed with broad valleys. They lie south of a second fault line (the Southern Uplands fault) that runs from Girvan to Dunbar . The geological foundations largely comprise Silurian deposits laid down some 400 to 500 million years ago. The high point of

The first Union Jack was designed at James's behest, to be flown in addition to the St Andrew's Cross on Scots vessels at sea. James VI and I intended to create a single kingdom of Great Britain, but was thwarted in his attempt to do so by the Parliament of England , which supported the wrecking proposal that

9222-452: The sea floor. Researcher Jason Hall-Spencer of the University of Glasgow had found pieces of coral at least 4,500 years old in the nets of trawlers operating off the coast of Ireland and Scotland. Pieces of coral up to 1 square metre (11 sq ft) were found in the nets of French trawling vessels that had been scraping the seabed 1 kilometre (0.6 mi) down. It is known that much coral

On 22 March 2004 EU Fisheries Ministers in Brussels agreed to give permanent protection to the United Kingdom's unique cold-water coral reefs , recognising the Darwin Mounds as an important habitat. In 2004 deep-water bottom trawling in

9646-476: The technological developments of the Industrial Revolution throughout Britain. In literature, the most successful figure of the mid-19th century was Walter Scott . His first prose work, Waverley in 1814, is often called the first historical novel.
