Rudolf I, also known as Rudolf of Habsburg (German: Rudolf von Habsburg, Czech: Rudolf Habsburský; (1218-05-01)1 May 1218 – 15 July 1291(1291-07-15)), was Count of Habsburg from about 1240 and elected King of Germany (King of the Romans) from 1273 until his death.
Rudolf's election marked the end of the Great Interregnum in the Holy Roman Empire after the death of the Hohenstaufen emperor Frederick II in 1250. Originally a Swabian count, he was the first Habsburg to acquire the duchies of Austria and Styria against his mighty rival, the Přemyslid king Ottokar II of Bohemia, whom he defeated in the 1278 Battle on the Marchfeld. The territories would remain under Habsburg rule for more than 600 years, they would form the core of the Habsburg Monarchy and the present-day country of Austria
The first German king of the Habsburg dynasty, he played a vital role in raising the comital house to the rank of Imperial princes. He was also the first in a number of late medieval count-kings, so-called by the historian Bernd Schneidmüller, from the rivalling noble houses of Habsburg, Luxembourg, and Wittelsbach, all striving after the Roman-German royal dignity, which ultimately was taken over by the Habsburgs in 1438.
Rudolph I (859 – October 25, 912) was King of (Upper or Transjurane) Burgundy from his election in 888 until his death.
Rudolph belonged to the elder Welf family and was the son of Conrad, Count of Auxerre and Waldrada of Worms. From his father he inherited the lay abbacy of St Maurice en Valais, making him the most powerful magnate in Upper Burgundy - present-day western Switzerland and the Franche-Comté.
After the deposition and death of Charles the Fat, the nobles and leading clergy of Upper Burgundy met at St Maurice and elected Rudolph as king. Apparently on the basis of this election, Rudolph claimed the whole of Lotharingia, taking much of modern Lorraine and Alsace - but his claim was contested by Arnulf of Carinthia, the new king of East Francia or Germany, who rapidly forced Rudolph to abandon Lotharingia in return for recognition as king of Burgundy. However, hostilities between Rudolph and Arnulf seem to have continued intermittently until 894.
Rudolph's relationships with his other neighbours were friendlier. His sister Adelaide married Richard the Justiciar, duke of Burgundy (the present day Burgundy, part of west Francia). His daughter another Adelaide married Louis the Blind of Provence (Lower Burgundy), and his daughter Willa married Boso of Tuscany.

Rudolf I (died 3 August 908) was the Bishop of Würzburg from 892 until his death. He was the youngest son of Udo of Neustria.
In 892, he was appointed as bishop to replace Arno, who had been killed during a campaign against Great Moravia. At the same time, his brother Conrad the Elder became Margrave of Thuringia, reflecting the influence the family held within East Francia. It is probable that Arnulf was switching his patronage from one family to another, because Poppo, Duke of Thuringia, a Babenberg, was deposed for counselling Arno to campaign. Soon after the Babenbergs and Conradines were in a feud.
Rudolf was killed in 908 while fighting against the Magyars in Thuringia.
