Bishop of Chur

[1][2] A Bishop of Chur is first mentioned in 451/452 when Asinius attended the Synod of Milan,[3] but probably existed a century earlier.

In the 7th century the bishopric acquired several territories south to the Lake of Constance.

In 958 Holy Roman Emperor Otto I gave the bishopric to his vassal Hartpert with numerous privileges including control over the Septimer Pass, at the time the main pass through the central Alps.

These concessions strengthened the bishopric's temporal power and later it became a princedom within the Holy Roman Empire.

At the time of the Hohenstaufen emperors in the 12th to early 13th centuries, some bishops of Chur were appointed by the emperor, which for a period led to existence of two bishops at the same time, the other being appointed by the pope.
