Sratsimir

The House of Sratsimir was a medieval Bulgarian noble house whose founder, the despot Sratsimir, held Lovech and married Keratsa Petritsa of the Asen dynasty. Their son Ivan Alexander seized the throne at Tarnovo in 1331, making the house the last ruling dynasty of the Second Bulgarian Empire.

After Ivan Alexander's death in 1371 his son Ivan Shishman ruled at Tarnovo while another son, Ivan Sratsimir, kept the separate empire of Vidin. Ottoman conquest ended both, with Tarnovo falling in 1393 and Vidin in 1422, when Constantine II of Vidin died as the last Bulgarian emperor.

The exile Fruzhin fought the Ottomans as a Hungarian count, and his descendants were recorded in Hungary into the sixteenth century. Later Bulgarian rebels, including leaders of the uprisings of 1598 and 1686, claimed descent from the house.
