Forced Conversions of Jews issued by Bishop Severus [Minorca; Present-day Spain] [Unconfirmed]
Commentary from other sources:
1) Severus, the Bishop of Minorca, claimed to have forced 540 Jews to accept Christianity upon conquering the Island. This is the first we know of Jews on this Island as well as the first case of Jews being forced to convert or face expulsion.
