89-512: The Gallego Flour Mills was a flour mill located in Richmond, Virginia , United States. Founded by Joseph Gallego in the 1790s, the mill gained international reputation for the superior type of flour that was shipped from there to Europe and South America. Further, the mills became iconic image of the defeated south after Mathew Brady shot a photo of the Mills after much of the city burned in 1865. At

178-457: A century there were more inventions developed and applied usefully than in the previous thousand years of human history all over the globe. The period saw major technological advances, including the adoption or invention of windmills , watermills , printing (though not yet with movable type), gunpowder , the astrolabe , glasses , scissors of the modern shape, a better clock , and greatly improved ships. The latter two advances made possible

267-414: A comprehensive production of alcohol. Food production also increased during this time as new ways of farming were introduced, including the use of a heavier plow, horses instead of oxen, and a three-field system that allowed the cultivation of a greater variety of crops than the earlier two-field system—notably legumes , the growth of which prevented the depletion of important nitrogen from the soil. During

356-533: A divine spark. Other notable scholastics included Muhammad Averroes , Roscelin , Abélard, Peter Lombard , and Francisco Suárez . One of the main questions during this time was the problem of universals . Prominent opponents of various aspects of the scholastic mainstream included Duns Scotus , William of Ockham , Peter Damian , Bernard of Clairvaux , and the Victorines . Christian heresies existed in Europe before

445-438: A high demand for wine and steady volume of alcohol consumption inspired a viticulture revolution of progress. The relative protection from famine during this time allowed Europe's population to increase, despite the famine in 1315 that killed 1.5 million people. This increased population contributed to the founding of new towns and an increase in industrial and economic activity during the period. They also established trade and

534-413: A husk. This foundation isolated the building from vibrations coming from the stones and main gearing and also allowed for the easy re-leveling of the foundation to keep the millstones perfectly horizontal. The lower bedstone was placed in an inset in the husk with the upper runner stone above the level of the husk. American inventor Oliver Evans revolutionized the labor-intensive process of early mills at

623-522: A key role in European trade from then on, making these cities become major financial centers. From the mid-10th to the mid-11th centuries, the Scandinavian kingdoms were unified and Christianized, resulting in an end of Viking raids, and greater involvement in European politics. King Cnut of Denmark ruled over both England and Norway. After Cnut's death in 1035, England and Norway were both lost, and with

712-412: A mechanical sieve to refine the flour, or turning a wooden drum to wind up a chain used to hoist sacks of grain to the top of the mill house. The distance between the stones can be varied to produce the grade of flour required; moving the stones closer together produces finer flour. This process, which may be automatic or controlled by the miller, is called tentering . The grain is lifted in sacks onto

801-463: A proportion on all grain processed in the community. Later, mills were supported by farming communities and the miller received the "miller's toll" in lieu of wages. Most towns and villages had their own mill so that local farmers could easily transport their grain there to be milled. These communities were dependent on their local mill as bread was a staple part of the diet. Classical mill designs are usually water-powered , though some are powered by

890-607: A religious experience and became a preacher. He founded the Waldensians which became a Christian sect believing that all religious practices should have strictly scriptural bases. Waldo was denied the right to preach his sermons by the Third Lateran Council in 1179, which he did not obey and continued to speak freely until he was excommunicated in 1184. Waldo was critical of the Christian clergy saying they did not live according to

979-462: A result of the First Crusade . In the context of the crusades, monastic military orders were founded that would become the template for the late medieval chivalric orders . The Knights Templar were a Christian military order founded after the First Crusade to help protect Christian pilgrims from hostile locals and highway bandits. The order was deeply involved in banking, and in 1307 Philip

1068-651: A single family. During the High Middle Ages Lithuania emerged as a Duchy of Lithuania in the early 13th century, then briefly becoming the Kingdom of Lithuania from 1251 to 1263. After the assassination of its first Christian king Mindaugas Lithuania was known as Grand Duchy of Lithuania . Unconquered during the Lithuanian Crusade , Lithuania itself rapidly expanded to the East due to conquests and became one of

1157-656: A successful Vlach-Bulgarian rebellion in 1185 , and henceforth the region was divided between the Byzantines in Greece, some parts of Macedonia , and Thrace , the Bulgarians in Moesia and most of Thrace and Macedonia, and the Serbs to the northwest. Eastern and Western churches had formally split in the 11th century, and despite occasional periods of co-operation during the 12th century, in 1204

1246-434: A system that allows the sequential milling of these grists, noting that "a mill, thus constructed, might grind grists in the day time, and do merchant-work at night." Over time, any small, older style flour mill became generally known as a gristmill (as a distinction from large factory flour mills). Modern mills typically use electricity or fossil fuels to spin heavy steel, or cast iron, serrated and flat rollers to separate

1335-498: A very physically demanding job for workers, where the slave workers were considered little different from animals, the miseries of which were depicted in iconography and Apuleius ' The Golden Ass . The peak of Roman technology is probably the Barbegal aqueduct and mill where water with a 19-metre fall drove sixteen water wheels , giving a grinding capacity estimated at 28 tons per day. Water mills seem to have remained in use during

1424-522: Is hardly exact, for the centre was at Toulouse and in the neighbouring districts. The Albigensians were strong in southern France, northern Italy, and the southwestern Holy Roman Empire . The Bogomils were strong in the Southeastern Europe , and became the official religion supported by the Bosnian kings . Peter Waldo of Lyon was a wealthy merchant who gave up his riches around 1175 after

1513-544: The Carolingian Empire had been divided and replaced by separate successor kingdoms called France and Germany, although not with their modern boundaries. Germany was significantly more eastern. Germany was under the banner of the Holy Roman Empire , which reached its high-water mark of unity and political power under Kaiser Frederick Barbarossa . During the successful reign of King David IV of Georgia (1089–1125),

1602-685: The Crusader States in the Levant . Other wars led to the Northern Crusades . The Christian kingdoms took much of the Iberian Peninsula from Muslim control, and the Normans conquered southern Italy, all part of the major population increases and the resettlement patterns of the era. The High Middle Ages produced many different forms of intellectual, spiritual and artistic works . The age also saw

1691-662: The Early Middle Ages and followed by the Late Middle Ages , which ended around AD 1500 (by historiographical convention). Key historical trends of the High Middle Ages include the rapidly increasing population of Europe, which brought about great social and political change from the preceding era, and the Renaissance of the 12th century , including the first developments of rural exodus and urbanization . By 1350,

1780-608: The Early Middle Ages was based upon few copies and commentaries of ancient Greek texts that remained in Western Europe after the collapse of the Western Roman Empire . Most of them were studied only in Latin as knowledge of Greek was very limited. This scenario changed during the Renaissance of the 12th century . The intellectual revitalization of Europe started with the birth of medieval universities . The increased contact with

1869-664: The Fourth Crusade treacherously captured Constantinople . This severely damaged the Byzantines, and their power was ultimately weakened by the Seljuks and the rising Ottoman Empire in the 14–15th century. The power of the Latin Empire , however, was short-lived after the Crusader army was routed by Bulgarian Emperor Kaloyan in the Battle of Adrianople (1205) . The Medieval Warm Period ,

1958-593: The Hanseatic League , a federation of free cities to advance trade by sea, was founded in the 12th century, with the foundation of the city of Lübeck , which would later dominate the League, in 1158–1159. Many northern cities of the Holy Roman Empire became Hanseatic cities, including Amsterdam , Cologne , Bremen , Hanover and Berlin. Hanseatic cities outside the Holy Roman Empire were, for instance, Bruges and

2047-647: The Kingdom of Georgia grew in strength and expelled the Seljuk Empire from its lands. David's decisive victory in the Battle of Didgori (1121) against the Seljuk Turks, as a result of which Georgia recaptured its lost capital Tbilisi , marked the beginning of the Georgian Golden Age . David's granddaughter Queen Tamar continued the upward rise, successfully neutralizing internal opposition and embarking on an energetic foreign policy aided by further decline of

2136-558: The Macedonian and Komnenos dynasties gradually gave way to the resurrected Serbia and Bulgaria and to a successor crusader state (1204 to 1261), who continually fought each other until the end of the Latin Empire. The Byzantine Empire was reestablished in 1261 with the recapture of Constantinople from the Latins, though it was no longer a major power and would continue to falter through

2225-622: The Matter of France (stories about Charlemagne and his court), the Acritic songs dealing with the chivalry of Byzantium's frontiersmen, and perhaps the best known cycle, the Matter of Britain , which featured tales about King Arthur , his court, and related stories from Brittany , Cornwall , Wales and Ireland. An anonymous German poet tried to bring the Germanic myths from the Migration Period to

2314-452: The Romanesque style by combining flying buttresses , gothic (or pointed) arches and ribbed vaults . It was influenced by the spiritual background of the time, being religious in essence: thin horizontal lines and grates made the building strive towards the sky. Architecture was made to appear light and weightless, as opposed to the dark and bulky forms of the previous Romanesque style . It

2403-596: The Silk Road to China. Westerners became more aware of the Far East when Polo documented his travels in Il Milione . He was followed by numerous Christian missionaries to the East, such as William of Rubruck , Giovanni da Pian del Carpine , André de Longjumeau , Odoric of Pordenone , Giovanni de' Marignolli , Giovanni di Monte Corvino , and other travellers such as Niccolò de' Conti . Philosophical and scientific teaching of

2492-438: The bran and germ from the endosperm . The endosperm is ground to create white flour, which may be recombined with the bran and germ to create whole grain or graham flour . The different milling techniques produce visibly different results, but can be made to produce nutritionally and functionally equivalent output. Stone-ground flour is preferred by many bakers and natural food advocates because of its texture, nutty flavour, and

2581-516: The intensive agriculture -prevalent model in Muslim-ruled lands did not require territorial expansion. While Muslim lands enjoyed a certain demographic and financial edge , Almoravids and Almohads from northern Africa featured volatile state structures; barring (unsuccessful) attempts to take Toledo, they did not stand out for carrying out an expansionist policy. In Italy, with the Norman conquest,

2670-413: The sack floor at the top of the mill on the hoist . The sacks are then emptied into bins, where the grain falls down through a hopper to the millstones on the stone floor below. The flow of grain is regulated by shaking it in a gently sloping trough (the slipper ) from which it falls into a hole in the center of the runner stone. The milled grain (flour) is collected as it emerges through the grooves in

2759-530: The 11th century but only in small numbers and of local character: in most cases, a rogue priest, or a village returning to pagan traditions. However, beginning in the 11th century, mass-movement heresies appeared. The roots of this can be partially sought in the rise of urban cities, free merchants, and a new money-based economy. The rural values of monasticism held little appeal to urban people who began to form sects more in tune with urban culture. The first large-scale heretical movements in Western Europe originated in

2848-516: The 12th century, the Cluny monks promoted ethical warfare and inspired the formation of orders of chivalry , such as the Templar Knights . Inherited titles of nobility were established during this period. In 13th-century Germany, knighthood became another inheritable title, although one of the less prestigious, and the trend spread to other countries. The East–West Schism of 1054 formally separated

2937-529: The 13th century had a great impact on the east of Europe , as many countries of the region were invaded, pillaged, conquered or vassalized. During the first half of this period ( c.  1025 —1185), Byzantine Empire dominated the Southeast Europe , and under the Komnenian emperors there was a revival of prosperity and urbanization; however, their domination of Southeast Europe was coming to an end with

3026-481: The 14th century, with remnants lasting until the mid 15th century. In the 11th century, populations north of the Alps began a more intensive settlement, targeting "new" lands, some areas of which had reverted to wilderness after the end of the Western Roman Empire . In what historian Charles Higounet called the "great clearances", Europeans cleared and cultivated some of the vast forests and marshes that lay across much of

3115-633: The British Isles, France and elsewhere, and Norse Christian kingdoms started developing in their Scandinavian homelands. The Magyars ceased their expansion in the 10th century, and by the year 1000, a Christian Kingdom of Hungary had become a recognized state in Central Europe that was forming alliances with regional powers. With the brief exception of the Mongol invasions in the 13th century, major nomadic incursions ceased. The powerful Byzantine Empire of

3204-486: The Christian church into two parts: Roman Catholicism in Western Europe and Eastern Orthodoxy in the east. It occurred when Pope Leo IX and Patriarch Michael I excommunicated each other, mainly over disagreement over the filioque , an addition to the creed concerning the origin of the Holy Spirit, as well as disputes as to the existence of papal authority over the four Eastern patriarchs , use of unleavened bread in

3293-655: The Fair (Philippine le Bel) had the entire order arrested in France and dismantled on charges of alleged heresy. The Knights Hospitaller were originally a Christian organization founded in Jerusalem in 1080 to provide care for poor, sick, or injured pilgrims to the Holy Land . After Jerusalem was taken in the First Crusade, it became a religious / military order that was charged with

3382-559: The High Middle Ages, the idea of a Christian warrior started to change as Christianity grew more prominent in Medieval Europe. The Codes of Chivalry promoted the ideal knight to be selfless, faithful, and fierce against those who threaten the weak. Household heavy cavalry ( knights ) became common in the 11th century across Europe, and tournaments were invented. Tournaments allowed knights to establish their family name while being able to gather vast wealth and renown through victories. In

Yet, both before and after the Order's main pagan opponent, Lithuania , converted to Christianity, the Order had already attacked other Christian nations such as Novgorod and Poland . The Teutonic Knights' power hold, which became considerable,

3560-692: The Islamic world in Spain and Sicily during the Reconquista , and the Byzantine world and Muslim Levant during the Crusades , allowed Europeans access to scientific Arabic and Greek texts, including the works of Aristotle , Alhazen , and Averroes . The European universities aided materially in the translation and propagation of these texts and started a new infrastructure which was needed for scientific communities. At

3649-619: The Platonist-Augustinian belief that the mind is an immaterial substance. The most famous of the scholastics was Thomas Aquinas (later declared a " Doctor of the Church "), who led the move away from the Platonic and Augustinian and towards Aristotelianism. Aquinas developed a philosophy of mind by writing that the mind was at birth a tabula rasa ("blank slate") that was given the ability to think and recognize forms or ideas through

Catharism was a movement with Gnostic elements that originated around the middle of the 10th century, branded by the contemporary Roman Catholic Church as heretical . It existed throughout much of Western Europe , but its origination was in Languedoc and surrounding areas in southern France. The name Cathar stems from Greek katharos , "pure". One of

By then, the natural science contained in these texts began to be extended by notable scholastics such as Robert Grosseteste , Roger Bacon , Albertus Magnus and Duns Scotus . Precursors of

4005-901: The belief that it is nutritionally superior and has a better baking quality than steel-roller-milled flour. It is claimed that, as the stones grind relatively slowly, the wheat germ is not exposed to the sort of excessive temperatures that could cause the fat from the germ portion to oxidize and become rancid, which would destroy some of the vitamin content. Stone-milled flour has been found to be relatively high in thiamin, compared to roller-milled flour, especially when milled from hard wheat. Gristmills only grind "clean" grains from which stalks and chaff have previously been removed, but historically some mills also housed equipment for threshing , sorting, and cleaning prior to grinding. Modern mills are usually "merchant mills" that are either privately owned and accept money or trade for milling grains or are owned by corporations that buy unmilled grain and then own

4094-420: The borderlands in the southern meseta . Agricultural models in areas with Mediterranean climate were generally based on biennial crop rotation . Despite population growth, agricultural output remained relatively rigid throughout the period; between the 10th and 13th centuries, migration southwards to exposed areas was incentivized by the possibility of enjoying privileges and acquiring properties. Conversely,

At the same time, settlers moved beyond the traditional boundaries of the Frankish Empire to new frontiers beyond the Elbe River , which tripled the size of Germany in the process. The Catholic Church , which reached the peak of its political power around then, called armies from across Europe to a series of Crusades against the Seljuk Turks . The crusaders occupied the Holy Land and founded

Crosby described some of this technological revolution in The Measure of Reality: Quantification in Western Europe, 1250-1600 and other major historians of technology have also noted it. Art in the High Middle Ages includes these important movements: Gothic architecture superseded

Meanwhile, Norway extended its Atlantic possessions, ranging from Greenland to the Isle of Man , while Sweden, under Birger Jarl , built up a power-base in the Baltic Sea . However, the Norwegian influence started to decline already in the same period, marked by the Treaty of Perth of 1266. Also, civil wars raged in Norway between 1130 and 1240. By

4628-421: The first great and powerful state was formed, the Kingdom of Sicily with hereditary monarchy. Subsequently joined to the Holy Roman Empire, it had its moment of maximum splendor with the emperor Frederick II . In the rest of Italy, independent city states grew affluent on Eastern Mediterranean maritime trade. These were in particular the thalassocracies of Pisa , Amalfi , Genoa and Venice , which played

The Cathars are also called Albigensians . This name originates from the end of the 12th century, and was used by the chronicler Geoffroy du Breuil of Vigeois in 1181. The name refers to the southern town of Albi (the ancient Albiga). The designation

Relying on a powerful military élite, Tamar was able to build on the successes of her predecessors to consolidate an empire which dominated vast lands spanning from present-day southern Russia on the Black Sea to the Caspian Sea . Georgia remained a leading regional power until its collapse under the Mongol attacks within two decades after Tamar's death. In the High Middle Ages, Hungary became one of

4984-413: The largest states in Europe. In the mid-10th century Poland emerged as a duchy after Mieszko I , the ruler of the Polans , conquered the surrounding Lechitic tribes in the region. Then in 1025 under the rule of Bolesław I the Brave , Poland became a kingdom. The High Middle Ages saw the height and decline of the Slavic state of Kievan Rus' and emergence of Cumania . Later, the Mongol invasion in

5073-427: The late 10th century onwards, there was an expansion of grist-milling in Northern Europe. In England, the Domesday survey of 1086 gives a precise count of England's water-powered flour mills: there were 5,624, or about one for every 300 inhabitants, and this was probably typical throughout western and southern Europe. From this time onward, water wheels began to be used for purposes other than grist milling. In England,

5162-431: The liturgy, and fasting days. The Catholic Crusades occurred between the 11th and 13th centuries. They were conducted under papal authority, initially with the intent of reestablishing Christian rule in The Holy Land by taking the area from the Muslim Fatimid Caliphate . The Fatimids had captured Palestine in AD 970, lost it to the Seljuk Turks in 1073 and recaptured it in 1098, just before they lost it again in 1099 as

The first wind-powered gristmills were built in the 9th and 10th centuries in what are now Afghanistan, Pakistan and Iran. The Egyptian town of Bilbays had a grain-processing factory that produced an estimated 300 tons of flour and grain per day. From

During the 12th and 13th century in Europe there was a radical change in the rate of new inventions, innovations in the ways of managing traditional means of production, and economic growth. In less than

5429-423: The most famous sacral building of the time: Notre Dame de Paris . A variety of cultures influenced the literature of the High Middle Ages, one of the strongest among them being Christianity. The connection to Christianity was greatest in Latin literature , which influenced the vernacular languages in the literary cycle of the Matter of Rome . Other literary cycles, or interrelated groups of stories, included

The Christian Kingdom of Hungary was established in 1000 under King Saint Stephen I of Hungary , and ruled by the Árpád dynasty for the following centuries. King Saint Ladislaus completed the work of King Saint Stephen . He consolidated the Hungarian state power and strengthened the influence of Christianity . His charismatic personality, strategic leadership and military talents resulted

These heresies were on a scale the Catholic Church had never seen before and as such the response was one of elimination for some (such as the Cathars ). Some Catholic monastic leaders, such as Francis of Assisi , the founder of the Franciscans , had to be recognized directly by

5696-460: The number of mills in operation followed population growth, and peaked at around 17,000 by 1300. Limited extant examples of gristmills can be found in Europe from the High Middle Ages . An extant well-preserved waterwheel and gristmill on the Ebro River in Spain is associated with the Real Monasterio de Nuestra Senora de Rueda , built by the Cistercian monks in 1202. The Cistercians were known for their use of this technology in Western Europe in

5785-496: The old wheel mills. In most wheel-driven mills, a large gear-wheel called the pit wheel is mounted on the same axle as the water wheel and this drives a smaller gear-wheel, the wallower , on a main driveshaft running vertically from the bottom to the top of the building. This system of gearing ensures that the main shaft turns faster than the water wheel, which typically rotates at around 10 rpm . The millstones themselves turn at around 120 rpm . They are laid one on top of

5874-414: The other. The bottom stone, called the bed , is fixed to the floor, while the top stone, the runner , is mounted on a separate spindle, driven by the main shaft. A wheel called the stone nut connects the runner's spindle to the main shaft, and this can be moved out of the way to disconnect the stone and stop it turning, leaving the main shaft turning to drive other machinery. This might include driving

5963-423: The paddles was transferred directly to the runner stone, causing it to grind against a stationary " bed ", a stone of a similar size and shape. This simple arrangement required no gears , but had the disadvantage that the speed of rotation of the stone was dependent on the volume and flow of water available and was, therefore, only suitable for use in mountainous regions with fast-flowing streams. This dependence on

6052-406: The palace of king Mithradates VI Eupator at Cabira , Asia Minor , before 71 BC. The early mills had horizontal paddle wheels, an arrangement which later became known as the " Norse wheel ", as many were found in Scandinavia. The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on

6141-422: The period 1100 to 1350. Although the terms "gristmill" or "corn mill" can refer to any mill that grinds grain, the terms were used historically for a local mill where farmers brought their own grain and received ground meal or flour, minus a percentage called the "miller's toll". Early mills in England were almost always built by the local lord of the manor and had the exclusive right (the right of mulcture ) to

6230-420: The period from the 10th century to about the 14th century in Europe, was a relatively warm and gentle interval ended by the generally colder Little Ice Age which would continue until the Middle of the 19th century. Farmers grew wheat well north into Scandinavia, and wine grapes in northern England, although the maximum expansion of vineyards appeared to occur within the Little Ice Age period. During this time,

6319-411: The period to expand Scholasticism , a combination of Judeo-Islamic and Catholic ideologies with the ancient philosophy. For much of this period, Constantinople remained Europe's most populous city, and Byzantine art reached a peak in the 12th century . In architecture, many of the most notable Gothic cathedrals were built or completed around this period. The Crisis of the Late Middle Ages began at

6408-580: The post-Roman period. Manually operated mills utilizing a crank-and-connecting rod were used in the Western Han dynasty . There was an expansion of grist-milling in the Byzantine Empire and Sassanid Persia from the 3rd century AD onwards, and then the widespread expansion of large-scale factory milling installations across the Islamic world from the 8th century onwards. Geared gristmills were built in

6497-418: The process. Evans himself did not use the term gristmill to describe his automatic flour mill, which was purpose designed as a merchant mill (he used the more general term "water-mill"). In his book his only reference to "grist" (or "grists") is to the small batches of grain a farmer would bring in to have ground for himself (what would be generally called barter or custom milling). In his book, Evans describes

6586-420: The rise of ethnocentrism , which evolved later into modern national identities in most of Europe, the ascent of the great Italian city-states and the rise and fall of the Islamic civilization of Al-Andalus . The rediscovery of the works of Aristotle , at first indirectly through medieval Jewish and Islamic philosophy , led Maimonides , Ibn Sina , Ibn Rushd , Thomas Aquinas and other thinkers of

6675-918: The robust population increase had greatly benefited the European economy, which had reached levels that would not be seen again in some areas until the 19th century. That trend faltered during the Late Middle Ages because of a series of calamities , most notably the Black Death , but also numerous wars as well as economic stagnation. From around 780, Europe saw the last of the barbarian invasions and became more socially and politically organized. The Carolingian Renaissance stimulated scientific and philosophical activity in Northern Europe. The first universities started operating in Bologna , Oxford , Paris , Salamanca , Cambridge and Modena . The Vikings settled in

The Exchequer was founded in the 12th century under King Henry I , and the first parliaments were convened. In 1215, after the loss of Normandy , King John signed the Magna Carta into law, limiting the power of English monarchs . A key geo-strategic development in the Iberian Peninsula was the Christian conquest of Toledo in 1085. Dominated by war,
