CastleA castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars usually consider a castle to be the private fortified residence of a lord or noble. This is distinct from a mansion, palace and villa, whose main purpose was exclusively for pleasance and are not primarily fortresses but may be fortified. Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles.
FranksThe Franks (Franci or gens Francorum; Francs) were originally a Germanic people who lived near the Lower Rhine, on the northern frontier of the late Roman Empire, but they successfully expanded their power and influence during the Middle Ages, until much of the population of western Europe, particularly in or near France, were commonly described as Franks, for example in the context of their joint efforts during the crusades starting in the 11th century.
Carolingian dynastyThe Carolingian dynasty (ˌkærəˈlɪndʒiən ; known variously as the Carlovingians, Carolingus, Carolings, Karolinger or Karlings) was a Frankish noble family named after Charlemagne, grandson of mayor Charles Martel and a descendant of the Arnulfing and Pippinid clans of the 7th century AD. The dynasty consolidated its power in the 8th century, eventually making the offices of mayor of the palace and dux et princeps Francorum hereditary, and becoming the de facto rulers of the Franks as the real powers behind the Merovingian throne.
Ancient Roman architectureAncient Roman architecture adopted the external language of classical Greek architecture for the purposes of the ancient Romans, but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and to even a greater extent under the Empire, when the great majority of surviving buildings were constructed.
CharlemagneCharlemagne (ˈʃɑːrləmeɪn,_ˌʃɑːrləˈmeɪn ) or Charles the Great (Carolus Magnus, Frankish: Karl; 2 April 747 – 28 January 814), a member of the Carolingian dynasty, was King of the Franks from 768, King of the Lombards from 774, and was crowned as the Emperor of the Romans by the Papacy in 800. Charlemagne succeeded in uniting the majority of western and central Europe and was the first recognized emperor to rule from western Europe after the fall of the Western Roman Empire approximately three centuries earlier.
