CataphractA cataphract was a form of armored heavy cavalry that originated in Persia and was fielded in ancient warfare throughout Eurasia and Northern Africa. The English word derives from the Greek κατάφρακτος kataphraktos (plural: κατάφρακτοι Kataphraktoi), literally meaning "armored" or "completely enclosed" (the prefix kata-/cata- implying "intense" or "completely"). Historically, the cataphract was a very heavily armored horseman, with both the rider and mount almost completely covered in scale armor, and typically wielding a kontos (lance) as his primary weapon.
CrusadesThe Crusades were a series of religious wars initiated, supported, and sometimes directed by the Christian Latin Church in the medieval period. The best known of these military expeditions are those to the Holy Land in the period between 1095 and 1291 that were intended to conquer Jerusalem and its surrounding area from Muslim rule. Beginning with the First Crusade, which resulted in the conquest of Jerusalem in 1099, dozens of military campaigns were organised, providing a focal point of European history for centuries.
Roman legionThe Roman legion (legiō, ˈɫɛɡioː), the largest military unit of the Roman army, comprised 5,200 infantry and 300 equites (cavalry) in the period of the Roman Republic (509 BC–27 BC) and 5,600 infantry and 200 auxilia in the period of the Roman Empire (27 BC – AD 476). The size of a typical legion varied throughout the history of ancient Rome, with complements ranging from 4,200 legionaries and 300 equites (drawn from the wealthier classes – in early Rome all troops provided their own equipment) in the Republic, to 5,500 in the Imperial period.
VandalsThe Vandals were a Germanic people who first inhabited what is now southern Poland. They established Vandal kingdoms on the Iberian Peninsula, Mediterranean islands, and North Africa in the fifth century. The Vandals migrated to the area between the lower Oder and Vistula rivers in the second century BC and settled in Silesia from around 120 BC. They are associated with the Przeworsk culture and were possibly the same people as the Lugii.
NormansThe Normans (Norman: Normaunds; Normands; Nortmanni/Normanni) were a population arising in the medieval Duchy of Normandy from the intermingling between Norse Viking settlers and indigenous West Franks and Gallo-Romans. The term is also used to denote emigrants from the duchy who conquered other territories such as England and Sicily. The Norse settlements in West Francia followed a series of raids on the French northern coast mainly from Denmark, although some also sailed from Norway and Sweden.
Walls of ConstantinopleThe Walls of Constantinople (Τείχη της Κωνσταντινουπόλεως) are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul in Turkey) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built.
