Richard of Cornwall vs Vladimir the Great

Richard of Cornwall was elected King of Germany by a faction of prince-electors, opposing Alfonso X of Castile. This election was part of the Great Interregnum, with Richard receiving support from the English crown and the Papacy.

Richard of Cornwall was crowned King of Germany in Aachen by the Archbishop of Cologne. His coronation was contested by Alfonso X, and Richard's authority was largely confined to the Rhineland and parts of southern Germany.

Richard of Cornwall returned to England after spending several years in Germany. His departure weakened his influence in the Holy Roman Empire, and he never returned, leaving the German throne contested until the end of the Great Interregnum.

Richard of Cornwall died at Berkhamsted Castle in England. His death ended his claim to the German throne, and he was succeeded by Rudolf of Habsburg, who ended the Great Interregnum.

Vladimir converted to Christianity and married Anna, sister of Byzantine Emperor Basil II, after capturing Chersonesus. He was baptized in Chersonesus, adopting the name Basil, and initiated the Christianization of Kievan Rus.

Vladimir ordered the mass baptism of the people of Kiev in the Dnieper River. Pagan idols were destroyed, and churches were built. This event established Christianity as the state religion of Kievan Rus.

Vladimir led a military campaign against the White Croats in the Carpathian region, expanding Kievan Rus' territory westward. This campaign secured control over important trade routes and tributary tribes.

Vladimir built the Church of the Tithes (Desyatynna Church) in Kiev, the first stone church in Kievan Rus. He dedicated a tenth of his income to its maintenance, symbolizing the institutionalization of Christianity.
