The Benedictine Pannonhalma Archabbey or Territorial Abbey of Saint Martin on Mount Pannonhalma is a medieval building in Pannonhalma and is one of the oldest historical monuments in Hungary. Founded in 996, it is located near the town, on top of a hill. Saint Martin of Tours is believed to have been born at the foot of this hill, hence its former name, Mount of Saint Martin, from which the monastery occasionally took the alternative name of Márton-hegyi Apátság. This is the second largest territorial abbey in the world, after the one in Monte Cassino.

Géza, also Gejza, was Grand Prince of the Hungarians from the early 970s. He was the son of Grand Prince Taksony and his Oriental—Khazar, Pecheneg or Volga Bulgarian—wife. He married Sarolt, a daughter of an Eastern Orthodox Hungarian chieftain. After ascending the throne, Géza made peace with the Holy Roman Empire. Within Hungary, he consolidated his authority with extreme cruelty, according to the unanimous narration of nearly contemporaneous sources. He was the first Hungarian monarch to support Christian missionaries from Western Europe. Although he was baptised, his Christian faith remained shallow and he continued to perform acts of pagan worship. He was succeeded by his son Stephen, who was crowned the first King of Hungary in 1000 or 1001.
