A year after becoming abbess, Matilda was assigned as regent of the kingdom when her father and brother
Otto went to Italy. As regent, Matilda held a reforming
synod at
Dornberg, concerning the church in Germany. In 968, the monk
Widukind of Corvey dedicated to Matilda his opus magnum
Die Sachsengeschichte, in which he called her the mistress of all Europe. The book, that described the history of the Saxons' struggle against the Magyars up to the death of
Otto I in 973, also served as a kind of manual for ruling, including advices on how to deal with deceit and betrayal. In 984, she held an
imperial diet at her abbey. At the diet,
Henry the Wrangler questioned the right of Matilda's nephew to succeed his father. Matilda successfully defeated his claims and secured the election of her nephew as Holy Roman Emperor, therefore "holding the empire together". A contemporary chronicler described her regency as being "without female levity". Matilda succeeded in restoring peace and authority by leading an army against the "
barbarians". In 985,
Wallhausen (now in
Saxony-Anhalt) became her private property. In 997, as Otto III increasingly shifted his focus to Italy (she accompanied him there in his first trip), he handed over the rulership of Germany to her, overriding the authority of all bishops and dukes. In seven years, she was the only member of the dynasty to have a presence in Saxony. In 998, she held a Diet (
Hoftag) in Derenburg, heard requests and appointed offices. In contemporary documents, she was called
metropolitana ("overseer of bishops) and
mattricia ("
matriarch"). == Death ==
