Salian dynasty
Upon the death of Henry V in 1125, the last member of the Salian dynasty, his elected successor Lothair of Supplinburg attempted to seize the crown lands from the Hohenstaufen Frederick II, Duke of Swabia and his brother Conrad who considered all these lands, including Nuremberg Castle, to be part of the Salian family property inherited by them. After several sieges, Lothair succeeded in October 1130 in capturing the castle.
