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.
AlemanniThe Alemanni or Alamanni were a confederation of Germanic tribes on the Upper Rhine River during the first millennium. First mentioned by Cassius Dio in the context of the campaign of Roman emperor Caracalla of 213, the Alemanni captured the Agri Decumates in 260, and later expanded into present-day Alsace and northern Switzerland, leading to the establishment of the Old High German language in those regions, which by the eighth century were collectively referred to as Alamannia.
Holy Roman EmpireThe Holy Roman Empire, also known as the Holy Roman Empire of the German Nation after 1512, was a political entity usually headed by the Holy Roman Emperor in Central and Western Europe. It developed in the Early Middle Ages and continued until its dissolution in 1806 during the Napoleonic Wars. On 25 December 800, Pope Leo III crowned the Frankish king Charlemagne as Roman emperor, reviving the title in Western Europe more than three centuries after the fall of the ancient's Western Roman Empire in 476.
FeudalismFeudalism, also known as the feudal system, was the combination of the legal, economic, military, cultural and political customs that flourished in medieval Europe between the 9th and 15th centuries. Broadly defined, it was a way of structuring society around relationships that were derived from the holding of land in exchange for service or labour. Although it is derived from the Latin word feodum or feudum (fief), which was used during the Medieval period, the term feudalism and the system which it describes were not conceived of as a formal political system by the people who lived during the Middle Ages.
