a feudal state in the second half of the 14th century in northwestern Bulgaria and the adjoining part of Serbia. The beginning of the Vidin Kingdom is usually taken to be about 1363, when it was separated by the Bulgarian tsar Ivan Alexander (reigned 1331-71) from his do-mains and transferred to his son Ivan Stratsimir. After Ivan Alexander’s death, Ivan Stratsimir subjugated the Sofia area. In 1365 the Vidin Kingdom was seized by the Hungarians; in 1369 or in early 1370, Ivan Stratsimir was restored to power as a Hungarian vassal. After the Turkish campaign of 1388, Ivan Stratsimir accepted the status of a Turkish vassal. The failure of the Crusade of 1396 led to the subjugation of the Vidin Kingdom by the Turkish sultan Bayazid.
