The Kingdom of Poland of the Jagiellons was the Polish state created by the accession of Wladislaus II Jagiełło, Grand Duke of Lithuania, to the Polish throne in 1386. The Union of Kreva united Poland and Lithuania – two separate states – under the rule of a single monarch, and later elected monarchs by both states happened to be the same persons. The union was transformed to a closer one by the Union of Lublin in 1569, which was shortly followed by the end of the Jagiellon dynasty that had ruled Poland for two centuries and Gediminids dynasty, that ruled Lithuania for about 400 years.
