Free imperial cityIn the Holy Roman Empire, the collective term free and imperial cities (Freie und Reichsstädte), briefly worded free imperial city (Freie Reichsstadt, urbs imperialis libera), was used from the fifteenth century to denote a self-ruling city that had a certain amount of autonomy and was represented in the Imperial Diet. An imperial city held the status of Imperial immediacy, and as such, was subordinate only to the Holy Roman Emperor, as opposed to a territorial city or town (Landstadt) which was subordinate to a territorial prince - be it an ecclesiastical lord (prince-bishop, prince-abbot) or a secular prince (duke (Herzog), margrave, count (Graf), etc.
Duchy of SaxonyThe Duchy of Saxony (Hartogdom Sassen, Herzogtum Sachsen) was originally the area settled by the Saxons in the late Early Middle Ages, when they were subdued by Charlemagne during the Saxon Wars from 772 and incorporated into the Carolingian Empire (Francia) by 804. Upon the 843 Treaty of Verdun, Saxony was one of the five German stem duchies of East Francia; Duke Henry the Fowler was elected German king in 919.
SwabiaSwabia is a cultural, historic and linguistic region in southwestern Germany. The name is ultimately derived from the medieval Duchy of Swabia, one of the German stem duchies, representing the territory of Alemannia, whose inhabitants interchangeably were called Alemanni or Suebi. This territory would include all of the Alemannic German area, but the modern concept of Swabia is more restricted, due to the collapse of the duchy of Swabia in the thirteenth century.
Second CrusadeThe Second Crusade (1145–1149) was the second major crusade launched from Europe. The Second Crusade was started in response to the fall of the County of Edessa in 1144 to the forces of Zengi. The county had been founded during the First Crusade (1096–1099) by King Baldwin I of Jerusalem in 1098. While it was the first Crusader state to be founded, it was also the first to fall. The Second Crusade was announced by Pope Eugene III, and was the first of the crusades to be led by European kings, namely Louis VII of France and Conrad III of Germany, with help from a number of other European nobles.
