1000: Stephen I establishes the Kingdom of Hungary. After migrating from the East, the Magyars had been defeated by Otto I at the Battle of Lechfield in 955, and settled down. For the next 45 years, they existed in a limbo with respect to the other states of Europe, until Stephen’s coronation finally established Hungary as a Christian kingdom. It would last until its defeat at Mohacs in 1526, when it was absorbed into the Ottoman Empire.
1066: William the Conqueror is crowned at Westminster Abbey as William I. After the death of Edward the Confessor, Harold Godwinson had ascended the throne. William, Duke of Normandy, claimed that he had a more valid right than Harold, and invaded the kingdom of England from Normandy. William won, and set up the Norman system of rule in England which meant that French kings would rule in England until 1485.
