Tsardom of Vidin

The Tsardom of Vidin (, Vidinsko Carstvo) was a medieval Bulgarian state centred in the town of Vidin. In 1257 the local lord Rostislav Mikhailovich was crowned as Tsar of Bulgaria in Tarnovo, but soon withdrew to Vidin. In 1356, Bulgarian tsar Ivan Alexander isolated Vidin from the Bulgarian monarchy and appointed his son Ivan Stratsimir (1356–1396) as absolute ruler of the domain of Vidin.
