William (marcha orientalis)

William (II) was the margrave (comes terminalis, "frontier count") of the March of Pannonia in the mid ninth century until his death on campaign against the Moravians in 871. In his day, the march orientalis corresponded to a front along the Danube from the Traungau to Szombathely and the Rába river and including the Vienna basin. It was a military frontier zone against Avaria.

William co-ruled the march with his brother Engelschalk I and both died on the same campaign. They were replaced by Aribo, but Engelschalk's son Engelschalk II led their heirs in rebellion against Aribo in what became known as the Wilhelminer War from 882 to 884. The "Wilhelminers" were descendants of William's father, William I.

William (archbishop of Mainz)

William (929 – 2 March 968) was Archbishop of Mainz from 17 December 954 until his death. He was the son of the Emperor Otto I the Great and a Slav mother.

On 17 December 954, he was appointed to the archbishopric of Mainz following the death of the rebellious former archbishop Frederick. William received confirmation from Pope Agapetus II and also the title of Apostolic Vicar of Germany, a title which made the archbishops of Mainz the pope's deputies in Germany and granted the archdiocese of Mainz the title of Holy See. From his father William also received the title of "Arch-Chaplain of the Empire."

William died at Rottleberode in 968 and was buried in St. Alban's Abbey, Mainz.
