context_page_description: Regensberg was a family of counts from the Canton of Zürich in Switzerland. The family had possessions in the medieval Zürichgau from the probably mid-11th century and became extinct in 1331 AD. With the extinction of the male line, the city republic of Zürich laid claim to the Regensberg lands and formed the Herrschaft Regensberg respectively Äussere Vogtei.
context_section_description: The origins of the family are unclear, and various speculations by also renowned historians have not been proven so far. The so-called Hunfried document of 1044 AD mentions among others a witness named Lütold of Affoltern who is suspected as the builder of the ancestral seat around 1050, the Alt-Regensberg Castle on the border between Regensdorf and Zürich-Affoltern. In 1083 Lütold I von Regensberg, Kastvogt of the Muri Abbey, is mentioned as the first bearer of the name and supposedly son of Lütold von Affoltern. Lütold II and his wife Judenta and their son Lütold III donated goods to build a nunnery, the later Fahr Abbey in 1130. Lütold III was associated in the 1180s with the House of Zähringen.
