113-578: The Caledonian Railway Bridge is a bridge crossing the River Clyde at Broomielaw in Scotland . It is adjacent to Glasgow Central Station . The first bridge was built between 1876 and 1878 for the Caledonian Railway Company and opened on 1 August 1879. It was engineered by Blyth and Cunningham and built by Sir William Arrol & Co. It consisted of wrought iron lattice girders linked at
226-503: A river source heat pump scheme in the area called Queens Quay. It is the first large heat pump scheme in Britain to deliver at 80 °C. The heat pumps were supplied by Star Refrigeration Ltd, who manufactured them in their Glasgow factory. The project was delivered by Vital Energi. Celtic Britons The Britons ( * Pritanī , Latin : Britanni , Welsh : Brythoniaid ), also known as Celtic Britons or Ancient Britons , were
339-510: A "plausible vector for the spread of early Celtic languages into Britain". There was much less migration into Britain during the subsequent Iron Age, so it is more likely that Celtic reached Britain before then. Barry Cunliffe suggests that a branch of Celtic was already being spoken in Britain and that the Bronze Age migration introduced the Brittonic branch. The Anglo-Saxon Chronicle , which
452-544: A 46-ton cutter, was built by Scotts of Greenock in 1803. The pre-eminent Scottish yacht designer William Fyfe did not start designing yachts until 1807. The first yacht club on the Clyde was the Northern Yacht Club , which was established in 1824 and received its royal charter in 1831. The club was founded to organise and encourage the sport of yacht racing. By 1825, Scottish and Irish clubs were racing against each other on
565-518: A bard . The medieval Welsh form of Latin Britanni was Brython (singular and plural). Brython was introduced into English usage by John Rhys in 1884 as a term unambiguously referring to the P-Celtic speakers of Great Britain, to complement Goidel ; hence the adjective Brythonic refers to the group of languages. " Brittonic languages " is a more recent coinage (first attested in 1923 according to

Despite the strategic location and flat terrain of Glasgow and the surrounding Clyde basin, no Roman civilian settlement was ever constructed. Instead, the region may have functioned as a frontier zone between the Roman province known as Britannia Inferior and the Caledonians , an indigenous group that
1017-457: A heat source. The flow rate downstream alone is around 50 m /s. Reducing this temperature by 3 °C would enable river heat pumps to extract 188.1 MW of heat. Since river heat pumps typically have an efficiency of 3.0, the heat deliverable is 1.5 times the river component. As a result, the estuary could deliver 282 MW of heat. The temperature of industrial heat pump delivery is typically 80 °C. In 2020, West Dunbartonshire Council deployed
1130-454: A long but declining history of coal usage and, beginning around the 1950s, an increasing reliance on petroleum fuels. The decline of hydrocarbon pollution was followed by the appearance of PCB concentrations in the 1950s. Total PCB concentration levels peaked in the period 1965 to 1977, and declined beginning in the 1990s. The Polmadie Burn , which flows into the Clyde at Richmond Park , remains heavily contaminated by hexavalent chromium , to

Aeron , which encompassed modern Ayrshire , was conquered by the Anglo-Saxon kingdom of Northumbria by 700 AD. Some Brittonic kingdoms were able to successfully resist these incursions: Rheged (encompassing much of modern Northumberland and County Durham and areas of southern Scotland and

The Clyde Port Authority Confirmation Act 1965 (c. xlv) replaced the Clyde Navigation Trust with the Clyde Port Authority from 1 January 1966, which has since been renamed to 'Clydeport', and was privatisated in 1992. In 2003 it was acquired by Peel Holdings . The Clyde is formed by the confluence of two streams,

In the early Middle Ages , following the Anglo-Saxon settlement of Britain , the Anglo-Saxons called all Britons Bryttas or Wealas (Welsh), while they continued to be called Britanni or Brittones in Medieval Latin . From the 11th century, they are more often referred to separately as the Welsh , Cumbrians , Cornish , and Bretons , as they had separate political histories from then. From
2034-505: The 7th century , Saint Mungo established a new Christian community on the banks of the Clyde, potentially replacing Cathures if this is assumed to have occupied the same locus. This community was the beginnings of what would become the city of Glasgow. Several villages along the Clyde that were founded in or before this period have endured to this day, and have grown to become towns, including Llanerc ( Lanark ), Cadzow ( Hamilton ), and Rhynfrwd ( Renfrew ). The fortress of Altclut fell in

Caer Went had officially disappeared by 575 AD becoming the Anglo-Saxon kingdom of East Anglia . Gwent was only partly conquered; its capital Caer Gloui ( Gloucester ) was taken by the Anglo-Saxons in 577 AD, handing Gloucestershire and Wiltshire to the invaders, while the westernmost part remained in Brittonic hands, and continued to exist in modern Wales.

Caer Celemion (in modern Hampshire and Berkshire) had fallen by 610 AD. Elmet, a large kingdom that covered much of modern Yorkshire, Lancashire, and Cheshire and likely had its capital at modern Leeds,
2938-614: The Industrial Revolution was due to the location of Glasgow, as a port facing the Americas. Tobacco and cotton trade began to drive this economic engine in the early 18th century. However, an obstacle to further economic growth soon became evident: the Clyde was too shallow for the largest ocean-going ships to navigate into it, so cargo had to be transferred, at Greenock or Port Glasgow , to smaller ships that could sail upstream into Glasgow itself. In 1768, John Golborne advised that

Similarly, the Brittonic colony of Britonia in northwestern Spain appears to have disappeared soon after 900 AD. The kingdom of Ystrad Clud (Strathclyde) was a large and powerful Brittonic kingdom of the Hen Ogledd (the 'Old North') which endured until the end of the 11th century, successfully resisting Anglo-Saxon, Gaelic Scots and later also Viking attacks. At its peak it encompassed modern Strathclyde, Dumbartonshire , Cumbria , Stirlingshire , Lanarkshire , Ayrshire , Dumfries and Galloway , Argyll and Bute , and parts of North Yorkshire ,

Over the same time period, it is estimated that more than 300 firms have engaged in shipbuilding on Clydeside, although probably at most 30 to 40 firms were operating at any given time. The shipbuilding firms became household names on Clydeside, and even around

After that, the kingdom, now politically weakened, possibly moved its capital to Govan . However, it never fully recovered, and in the 11th century it was annexed by the Kingdom of Alba . It did however retain some autonomy under the Church of Glasgow, which became the secular successors of much of
3729-537: The early modern period onwards, the Clyde began to be used commercially as a trade route; trade between Glasgow and the rest of Europe became commonplace. In the centuries that followed, the Clyde became increasingly vital to both Scotland and Britain as a major trade route for exporting and importing resources. The Clyde Navigation Trust was initially formed in 1840 by the Clyde Navigation Act 1840 ( 3 & 4 Vict. c. cxviii), and then reconstituted under

During World War II, the yard was devoted to Admiralty work, producing large, high-speed Fairmile Marine motor boats (motor torpedo boats and motor gun boats). After the war, the yard built the successful one-class Loch Longs and two 12 m (39 ft) challengers for the America's Cup , designed by David Boyd: Sceptre (1958) and Sovereign (1964).

4746-414: The Britons and Caledonians in the north remained unconquered and Hadrian's Wall became the edge of the empire. A Romano-British culture emerged, mainly in the southeast, and British Latin coexisted with Brittonic. It is unclear what relationship the Britons had with the Picts , who lived outside of the empire in northern Britain, however, most scholars today accept the fact that the Pictish language

The Channel Islands (colonised by Britons in the 5th century) came under attack from Norse and Danish Viking attack in the early 9th century AD, and by the end of that century had been conquered by Viking invaders. The Kingdom of Ce , which encompassed modern Marr , Banff , Buchan , Fife , and much of Aberdeenshire , disappeared soon after 900 AD. Fortriu ,

However, a later study showed PCB concentrations as high as 5,797 μg/kg, which is above published threshold levels for such chlorinated compounds. A comparison between individual PAH compounds that have different thermal stabilities shows that

Biggar is home to an archeological site at which Britain's most ancient artifacts have been unearthed. Prehistoric canoes , used by ancient peoples for transport or trade, have been found in the river. There are a number of Mesolithic sites along the Clyde, especially in
5198-537: The Clyde's importance as a major industrial centre rapidly declined. During the war, the Luftwaffe singled out Clydebank for bombing , and its buildings sustained heavy damage. In the immediate postwar period, the sharp reduction in warship orders was initially balanced by a prolonged boom in merchant shipbuilding. But by the end of the 1950s, other countries had begun to establish well-capitalised and highly productive shipbuilding centres that were able to outcompete many of

During the 19th century, many Welsh farmers migrated to Patagonia in Argentina , forming a community called Y Wladfa , which today consists of over 1,500 Welsh speakers. In addition, a Brittonic legacy remains in England, Scotland and Galicia in Spain, in the form of often large numbers of Brittonic place and geographical names. Examples of geographical Brittonic names survive in

The British tribes opposed the Roman legions for many decades, but by 84 AD the Romans had decisively conquered southern Britain and had pushed into Brittonic areas of what would later become northern England and southern Scotland. During the same period, Belgic tribes from the Gallic-Germanic borderlands settled in southern Britain. Caesar asserts the Belgae had first crossed

Pictish is now generally accepted to descend from Common Brittonic, rather than being a separate Celtic language. Welsh and Breton survive today; Cumbric and Pictish became extinct in the 12th century. Cornish had become extinct by the 19th century but has been the subject of language revitalization since

The "evidence suggests that rather than a violent invasion or a single migratory event, the genetic structure of the population changed through sustained contacts between mainland Britain and Europe over several centuries, such as the movement of traders, intermarriage, and small-scale movements of family groups". The authors describe this as

In 2021, a major archaeogenetics study uncovered a migration into southern Britain during the Bronze Age , over a 500-year period from 1,300 BC to 800 BC. The migrants were "genetically most similar to ancient individuals from France" and had higher levels of Early European Farmers ancestry. From 1000 to 875 BC, their genetic marker swiftly spread through southern Britain, making up around half

More recently, John Koch and Barry Cunliffe have challenged that with their 'Celtic from the West' theory, which has the Celtic languages developing as a maritime trade language in the Atlantic Bronze Age cultural zone before it spread eastward. Alternatively, Patrick Sims-Williams criticizes both of these hypotheses to propose 'Celtic from the Centre', which suggests Celtic originated in Gaul and spread during

In the mid-19th century, engineers took on the task of dredging the Clyde much more extensively. They removed millions of cubic feet of silt to deepen and widen the channel. The major stumbling block encountered by that project was a massive geological intrusion known as Elderslie Rock . Because that rock increased

One shipyard that was known as a 'Clyde' shipyard was not actually located on any of the Clyde's waterways: Alley & MacLellan 's Sentinel Works in Jessie Street at Polmadie
8249-532: The male side. Wales, Cornwall, Brittany and the Isles of Scilly continued to retain a distinct Brittonic culture, identity and language, which they have maintained to the present day. The Welsh and Breton languages remain widely spoken, and the Cornish language , once close to extinction, has experienced a revival since the 20th century. The vast majority of place names and names of geographical features in Wales, Cornwall,
8362-680: The mid 11th century AD when Cornwall was effectively annexed by the English, with the Isles of Scilly following a few years later, although at times Cornish lords appear to have retained sporadic control into the early part of the 12th century AD. Wales remained free from Anglo-Saxon, Gaelic Scots and Viking control, and was divided among varying Brittonic kingdoms, the foremost being Gwynedd (including Clwyd and Anglesey ), Powys , Deheubarth (originally Ceredigion , Seisyllwg and Dyfed ), Gwent , and Morgannwg ( Glamorgan ). These Brittonic-Welsh kingdoms initially included territories further east than
8475-470: The modern borders of Wales; for example, Powys included parts of modern Merseyside , Cheshire and the Wirral and Gwent held parts of modern Herefordshire , Worcestershire , Somerset and Gloucestershire , but had largely been confined to the borders of modern Wales by the beginning of the 12th century. However, by the early 1100s, the Anglo-Saxons and Gaels had become the dominant cultural force in most of
8588-587: The names of rivers, such as the Thames , Clyde , Severn , Tyne , Wye , Exe , Dee , Tamar , Tweed , Avon , Trent , Tambre , Navia , and Forth . Many place names in England and Scotland are of Brittonic rather than Anglo-Saxon or Gaelic origin, such as London , Manchester , Glasgow , Edinburgh , Carlisle , Caithness , Aberdeen , Dundee , Barrow , Exeter , Lincoln , Dumbarton , Brent , Penge , Colchester , Gloucester , Durham , Dover , Kent , Leatherhead , and York . Schiffels et al. (2016) examined
8701-535: The native Britons south of Hadrian's Wall mostly kept their land, they were subject to the Roman governors , whilst the Brittonic-Pictish Britons north of the wall probably remained fully independent and unconquered. The Roman Empire retained control of "Britannia" until its departure about AD 410, although parts of Britain had already effectively shrugged off Roman rule decades earlier. Thirty years or so after
8814-404: The north bank of the river. At the time of its opening, it was believed to be the widest railway bridge in existence. 55°51′20.8″N 4°15′32.2″W / 55.855778°N 4.258944°W / 55.855778; -4.258944 River Clyde The River Clyde ( Scottish Gaelic : Abhainn Chluaidh , pronounced [ˈavɪɲ ˈxl̪ˠuəj] ) is a river that flows into
8927-482: The open sea. Shipping and shipbuilding grow in Glasgow and its neighbouring industrial burghs of Govan and Partick ; with the Clyde, including is lower reaches, becoming the centre of world shipbuilding. The river then flows west, out of Glasgow, past Renfrew , under the Erskine Bridge , and past Dumbarton on the northern shore and the sandbank at Ardmore Point between Cardross and Helensburgh . Opposite, on
9040-480: The political framework was a British culture of Welsh speakers that was politically unified and formed a centralised kingdom known as Alt Clut, representing the power centre at Dunbarton Rock. None of the documentary or archaeological evidence from the period when the Roman legions arrived suggests that battles took place in the area. Therefore the Roman legions and Damnonii tribespeople are assumed to have been on good terms and to have co-operated by means of trade and
9153-520: The post-Roman Celtic speakers of Armorica were colonists from Britain, resulting in the Breton language , a language related to Welsh and identical to Cornish in the early period, and is still used today. Thus, the area today is called Brittany (Br. Breizh , Fr. Bretagne , derived from Britannia ). Common Brittonic developed from the Insular branch of the Proto-Celtic language that developed in
9266-467: The power of the Falls of Clyde , the most spectacular of which is Cora Linn. A hydroelectric power station still generates 11MW of electricity there today, although the mills have now become a museum and World Heritage Site . The river then makes its way northwest, past the towns of Wishaw to the east of it and Larkhall to the west of it. The river's surroundings here become increasingly suburban. Between
9379-411: The pre-Roman Iron Age , until the central Middle Ages ". The earliest known reference to the inhabitants of Britain was made by Pytheas , a Greek geographer who made a voyage of exploration around the British Isles between 330 and 320 BC. Although none of his own writings remain, writers during the following centuries make frequent reference to them. The ancient Greeks called the people of Britain
9492-563: The problem, so in 1773, a training wall called the Lang Dyke was built on the Dumbuck shoal to stop water flowing over into the southern channel of the river. In the late 18th and early 19th centuries, hundreds of jetties were built out from the banks of the river between Dumbuck and the Broomielaw quay in Glasgow proper. In some cases, this construction had the effect of deepening the river, because
9605-399: The project's difficulty, the work was not completed until the 1880s. Around this time, the Clyde became an important source of inspiration for artists, such as John Atkinson Grimshaw and James Kay , who were interested in painting scenes that depicted the new industrial era and the modern world. The completion of the dredging was well-timed, because the channel finally became navigable all
9718-548: The regions of modern East Anglia , East Midlands , North East England , Argyll , and South East England were the first to fall to the Germanic and Gaelic Scots invasions. The kingdom of Ceint (modern Kent) fell in 456 AD. Linnuis (which stood astride modern Lincolnshire and Nottinghamshire) was subsumed as early as 500 AD and became the English Kingdom of Lindsey. Regni (essentially modern Sussex and eastern Hampshire )
9831-515: The remains of three Iron Age Britons buried ca. 100 BC. A female buried in Linton, Cambridgeshire carried the maternal haplogroup H1e , while two males buried in Hinxton both carried the paternal haplogroup R1b1a2a1a2 , and the maternal haplogroups K1a1b1b and H1ag1 . Their genetic profile was considered typical for Northwest European populations. Though sharing a common Northwestern European origin,
9944-505: The river should be made narrower and the scour increased by constructing rubble jetties and dredging sandbanks and shoals . Another obstacle to navigation that had to be solved was that the river divided into two shallow channels by the Dumbuck shoal near Dumbarton . After James Watt 's 1769 report describing this problem, a jetty was constructed at Longhaugh Point to block off the southern channel. This turned out to be insufficient to solve
10057-572: The river's shipyards were given contracts to build prestigious ocean-going liners, as well as warships. The Queen Mary and, in later years, the Queen Elizabeth 2 were built in the town of Clydebank . Between 1712, when the Scott family's shipyard was built at Greenock, and the present day, over 25,000 ships have been built on the River Clyde, its firth, and its tributaries , the River Kelvin and
10170-595: The source of PAH pollution in the Clyde is different in different parts of the river. PAH in the inner Clyde (Cuningar to Milton) are from combustion sources (vehicle exhaust, coal burning), whereas PAH in the outer Clyde are from petroleum spills. The amount and type of sedimentary pollution in the Clyde reflects the area's industrial history. In order to assess how the nature of the pollutants has changed over time, from 1750 to 2002, seven sediment cores of one metre's depth were collected, and dated using lead concentrations and changing lead isotope ratios. The sediments showed
10283-452: The source of the River Annan . From there, it meanders northeastward before turning to the west, where its flood plain serve as the site of many major roads in the area, then reaches the town of Lanark , where the late 17th- and early 18th-century industrialists David Dale and Robert Owen built mills and the model settlement of New Lanark on the banks of the Clyde. The mills harnessed
10396-453: The southeastern part of Glasgow, the river begins to widen, meandering through Cambuslang , Rutherglen , and Dalmarnock , and past Glasgow Green . From the Tidal Weir westwards, the river is tidal : a mix of fresh and salt water. Over three centuries the river has been engineered and widened where it passes through Glasgow city centre and onwards towards Dumbarton and Greenock and
10509-501: The southern shore, is the last remaining Lower Clyde shipyard, at Port Glasgow . The river continues on to Greenock , where it reaches the Tail of the Bank as the river merges into the Firth of Clyde . Here at the mouth of the Clyde, there is currently a significant ecological problem of oxygen depletion in the water column. The economic prosperity that the Clyde made possible at the beginning of
10622-588: The territory when it was treated as a Principality of the Scottish Crown. In the 13th century, Glasgow, then still a small town, built its first bridge over the river Clyde. This was an important step in its ability to eventually grow into a city. The establishment, in the 15th century, of both the University of Glasgow and the Archdiocese of Glasgow , vastly increased the importance of the town within Scotland. From
10735-554: The time of the Roman departure, the Germanic -speaking Anglo-Saxons began a migration to the south-eastern coast of Britain, where they began to establish their own kingdoms, and the Gaelic -speaking Scots migrated from Dál nAraidi (modern Northern Ireland ) to the west coast of Scotland and the Isle of Man. At the same time, Britons established themselves in what is now called Brittany and
10848-407: The top by a light arched lattice girder, and carried on a cast iron arch (visible in the photograph) over twin piers in the river. The piers are formed of cast iron cylinders sunk to bedrock and filled with concrete, and then extended above the river with Dalbeattie granite . The approach span over Clyde Place to the south was 60 feet (18 m) long and over Broomielaw to the north of the river
10961-474: The towns of Motherwell and Hamilton , the course of the river has been altered to create an artificial loch within Strathclyde Park . Part of the original course can still be seen: It lies between the island and the eastern shore of the loch. The river then flows through Blantyre and Bothwell , where the ruined Bothwell Castle stands on a defensible promontory . As it flows past Uddingston and into
11074-475: The way from Greenock to Glasgow just when the steelwork industry had begun to grow in the city. Shipbuilding replaced trade as the major activity on the river, and shipbuilding companies started rapidly establishing themselves there. The Clyde soon gained a reputation for being the best location for shipbuilding in the British Empire , and grew to become the world's pre-eminent shipbuilding centre. The term Clydebuilt became an industry symbol of high quality, and
11187-561: The western Pennines , and as far as modern Leeds in West Yorkshire . Thus the Kingdom of Strathclyde became the last of the Brittonic kingdoms of the 'old north' to fall in the 1090s when it was effectively divided between England and Scotland. The Britons also retained control of Wales and Kernow (encompassing Cornwall , parts of Devon including Dartmoor , and the Isles of Scilly ) until
11300-418: The world to some extent. These included, among many others, John Brown & Company of Clydebank, Denny of Dumbarton, Scott of Greenock, Lithgows of Port Glasgow, Simon and Lobnitz of Renfrew, Alexander Stephen & Sons of Linthouse, Fairfield of Govan, Inglis of Pointhouse, Barclay Curle of Whiteinch, Connell and Yarrow of Scotstoun. Almost as famous were the engineering firms that supplied
11413-460: The yard turned to doing GRP production work (mainly building Pipers and Etchells), and it closed in 1980. During its 104-year history, Robertson's Yard built 500 boats, many of which are still sailing today. Two other notable boatyards on the Clyde were Silvers, which operated from 1910 to 1970, and McGruers, which operated from 1910 to 1973. They were situated on the Rosneath peninsula on the banks of
11526-431: Was 90 feet (27 m) long. The navigation spans were 164 feet (50 m), 184 feet (56 m) and 152 feet (46 m) long. The bridge carried four tracks into the new Glasgow Central Station. In 1966–1967, the girders and tracks were removed, leaving the pillars in the water, after resignalling meant it was no longer needed. The current, second bridge was built in 1899–1905 during the expansion of Central Station, to
11639-625: Was accompanied by wholesale population changes is still debated. During this time, Britons migrated to mainland Europe and established significant colonies in Brittany (now part of France), the Channel Islands , and Britonia (now part of Galicia , Spain). By the 11th century, Brittonic-speaking populations had split into distinct groups: the Welsh in Wales, the Cornish in Cornwall, the Bretons in Brittany,
11752-698: Was called Clut or Clud by the Britons and Clota by the Romans. It is therefore likely that the name comes from a Celtic language—most likely Old British . But there is more than one old Celtic word that the river's name could plausibly derive from. One possible root is the Common Brittonic Clywwd , meaning 'loud' or 'loudly'. More likely, the river was named after a local Celtic goddess, Clōta . The goddess's name in turn derives from an older, Proto-Celtic word meaning 'the strongly flowing one' or 'the holy cleanser'. Humans have settled along
11865-426: Was closely related to Common Brittonic. Following the end of Roman rule in Britain during the 5th century, Anglo-Saxon settlement of eastern and southern Britain began. The culture and language of the Britons fragmented, and much of their territory gradually became Anglo-Saxon , while the north became subject to a similar settlement by Gaelic -speaking tribes from Ireland. The extent to which this cultural change
11978-416: Was conquered by Gaelic Scots in 871 AD. Dumnonia (encompassing Cornwall , Devonshire , and the Isles of Scilly ) was partly conquered during the mid 9th century AD, with most of modern Devonshire being annexed by the Anglo-Saxons, but leaving Cornwall, the Isles of Scilly ( Enesek Syllan ), and for a time part of western Devonshire (including Dartmoor ), still in the hands of the Britons, where they became
12091-416: Was conquered by the Anglo-Saxons in 627 AD. Pengwern , which covered Staffordshire , Shropshire , Herefordshire , and Worcestershire , was largely destroyed in 656 AD, with only its westernmost parts in modern Wales remaining under the control of the Britons, and it is likely that Cynwidion, which had stretched from modern Bedfordshire to Northamptonshire, fell in the same general period as Pengwern, though
12204-416: Was hostile to the Romans. Strathclyde was founded as an independent unified British kingdom, quite some centuries after the Roman occupation of Britain . The kingdom's core territory and much of its arable land was located around the Clyde basin in the area traditionally associated with Alt Clut. The kingdom was ruled from its original capital, the near impenetrable Alt Clut fortress (Dumbarton Rock), which
12317-452: Was likely fully conquered by 510 AD. Ynys Weith (Isle of Wight) fell in 530 AD, Caer Colun (essentially modern Essex) by 540 AD. The Gaels arrived on the northwest coast of Britain from Ireland, dispossessed the native Britons, and founded Dal Riata which encompassed modern Argyll , Skye , and Iona between 500 and 560 AD. Deifr (Deira) which encompassed modern-day Teesside, Wearside, Tyneside, Humberside, Lindisfarne ( Medcaut ), and
12430-430: Was made up of many tribes and kingdoms, associated with various hillforts . The Britons followed an Ancient Celtic religion overseen by druids . Some of the southern tribes had strong links with mainland Europe, especially Gaul and Belgica , and minted their own coins . The Roman Empire conquered most of Britain in the 1st century AD, creating the province of Britannia . The Romans invaded northern Britain , but
12543-558: Was originally compiled by the orders of King Alfred the Great in approximately 890, starts with this sentence: "The island Britain is 800 miles long and 200 miles broad. And there are in the island five nations; English, Welsh (or British), Scottish, Pictish, and Latin. The first inhabitants were the Britons, who came from Armenia, and first peopled Britain southward" ("Armenia" is possibly a mistaken transcription of Armorica , an area in northwestern Gaul including modern Brittany ). In 43 AD,
12656-547: Was situated on the river and overlooked much of the estuary. This fortress was noteworthy enough to have been referred to at the time in several letters and poems about Sub-Roman Britain , written by Gildas and others. Strathclyde remained a powerful kingdom during the early medieval period in Britain. It was also a reservoir of native Welsh culture : Its territory expanded along the Clyde Vae Southern Uplands and Ayrshire, and eventually southwards into Cumbria. In
12769-463: Was used by Celtic Britons during war and ceremony. There are competing hypotheses for when Celtic peoples, and the Celtic languages, first arrived in Britain, none of which have gained consensus. The traditional view during most of the twentieth century was that Celtic culture grew out of the central European Hallstatt culture , from which the Celts and their languages reached Britain in the second half of
