The Holy Roman Empire was a multi-ethnic complex of territories in Western and Central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806 during the Napoleonic Wars.
Otto IV was one of two rival kings of Germany from 1198 on, sole king from 1208 on, and Holy Roman Emperor from 1209 until he was forced to abdicate in 1215. The only German king of the Welf dynasty, he incurred the wrath of Pope Innocent III and was excommunicated in 1210.
The Salian dynasty or Salic dynasty was a dynasty in the High Middle Ages. The dynasty provided four kings of Germany (1024–1125), all of whom went on to be crowned Holy Roman emperors (1027–1125).
Louis IV, called the Bavarian, of the house of Wittelsbach, was King of the Romans from 1314, King of Italy from 1327, and Holy Roman Emperor from 1328.
Frederick Barbarossa, also known as Frederick I, was the Holy Roman Emperor from 1155 until his death 35 years later. He was elected King of Germany at Frankfurt on 4 March 1152 and crowned in Aachen on 9 March 1152. He was crowned King of Italy on 24 April 1155 in Pavia and emperor by Pope Adrian IV on 18 June 1155 in Rome. Two years later, the term sacrum ("holy") first appeared in a document in connection with his empire. He was later formally crowned King of Burgundy, at Arles on 30 June 1178. He was named Barbarossa by the northern Italian cities which he attempted to rule: Barbarossa means "red beard" in Italian; in German, he was known as Kaiser Rotbart, which has the same meaning. The prevalence of the Italian nickname, even in later German usage, reflects the centrality of the Italian campaigns to his career.
Otto II, called the Red (Rufus), was Holy Roman Emperor from 973 until his death in 983. A member of the Ottonian dynasty, Otto II was the youngest and sole surviving son of Otto the Great and Adelaide of Italy.
Otto of Bamberg was Bishop of Bamberg and a missionary who, as papal legate, converted much of medieval Pomerania to Christianity.
The Duchy of Carinthia was a duchy located in southern Austria and parts of northern Slovenia. It was separated from the Duchy of Bavaria in 976, and was the first newly created Imperial State after the original German stem duchies.
The Guelphs and Ghibellines were factions supporting the Pope and the Holy Roman Emperor, respectively, in the Italian city-states of central and northern Italy. During the 12th and 13th centuries, rivalry between these two parties formed a particularly important aspect of the internal politics of medieval Italy. The struggle for power between the Papacy and the Holy Roman Empire arose with the Investiture Controversy, which began in 1075, and ended with the Concordat of Worms in 1122. The division between the Guelphs and Ghibellines in Italy, fuelled by the imperial Great Interregnum, persisted until the 15th century.
The House of Welf is a European dynasty that has included many German and British monarchs from the 11th to 20th century and Emperor Ivan VI of Russia in the 18th century.
The Free County of Burgundy or Franche-Comté, was a medieval county of the Holy Roman Empire, predecessor to the modern region of Franche-Comté. The name franc(he) comté derives from the title of its count, franc comte, in German Freigraf 'free count', denoting imperial immediacy. It should not be confused with the more westerly Duchy of Burgundy, a fiefdom of France since 843.
The Duchy of Bavaria was a frontier region in the southeastern part of the Merovingian kingdom from the sixth through the eighth century. It was settled by Bavarian tribes and ruled by dukes (duces) under Frankish overlordship. A new duchy was created from this area during the decline of the Carolingian Empire in the late ninth century. It became one of the stem duchies of the East Frankish realm which evolved as the Kingdom of Germany and the Holy Roman Empire.
Otto I of Brunswick-Lüneburg, a member of the House of Welf, was the first duke of Brunswick-Lüneburg from 1235 until his death. He is called Otto the Child to distinguish him from his uncle, Emperor Otto IV.
The Kingdom of Germany or German Kingdom was the mostly Germanic-speaking Eastern Frankish kingdom, which was formed by the Treaty of Verdun in 843, especially after the kingship passed from Frankish kings to the Saxon Ottonian dynasty in 919. The king was elected, initially by the rulers of the stem duchies, who generally chose one of their own. After 962, when Otto I was crowned emperor, East Francia formed the bulk of the Holy Roman Empire, which also included the Kingdom of Italy and, after 1032, the Kingdom of Burgundy.
Pandulf I Ironhead was the Prince of Benevento and Capua from 943 until his death. He was made Duke of Spoleto and Camerino in 967 and succeeded as Prince of Salerno in 977 or 978. He was an important nobleman in the fight with the Byzantines and Saracens for control of the Mezzogiorno in the centuries after the collapse of Lombard and Carolingian authority on the Italian Peninsula. He established himself over almost the whole of the southern half of Italia before his death in March 981.
The Kingdom of Italy, also called Imperial Italy, was one of the constituent kingdoms of the Holy Roman Empire, along with the kingdoms of Germany, Bohemia, and Burgundy. It comprised large parts of northern and central Italy. Its original capital was Pavia until the 11th century.
The Duchy of Austria was a medieval principality of the Holy Roman Empire, established in 1156 by the Privilegium Minus, when the Margraviate of Austria (Ostarrîchi) was detached from Bavaria and elevated to a duchy in its own right. After the ruling dukes of the House of Babenberg became extinct in male line, there was as much as three decades of rivalry on inheritance and rulership, until the German king Rudolf I took over the dominion as the first monarch of the Habsburg dynasty in 1276. Thereafter, Austria became the patrimony and ancestral homeland of the dynasty and the nucleus of the Habsburg Monarchy. In 1453, the archducal title of the Austrian rulers, invented by Duke Rudolf IV in the forged Privilegium Maius of 1359, was officially acknowledged by the Habsburg emperor Frederick III.
The March of Istria was originally a Carolingian frontier march covering the Istrian peninsula and surrounding territory conquered by Charlemagne's son Pepin of Italy in 789. After 1364, it was the name of the Istrian province of the Habsburg Monarchy, the Austrian Empire and Austria-Hungary.
Otto I, traditionally known as Otto the Great, was German king from 936 and Holy Roman Emperor from 962 until his death in 973. He was the oldest son of Henry I the Fowler and Matilda.
Henry II, also known as Saint Henry the Exuberant, Obl. S. B., was Holy Roman Emperor from 1014. He died without an heir in 1024, and was the last ruler of the Ottonian line. As Duke of Bavaria, appointed in 995, Henry became King of the Romans following the sudden death of his second cousin, Emperor Otto III in 1002, was made King of Italy in 1004, and crowned emperor by Pope Benedict VIII in 1014.
