Poland's written history begins with the reign of [[Mieszko I]], who accepted [[Christianity]] for himself and his kingdom in AD 966. The Polish state reached its zenith under the [[Jagiellonian dynasty]] in the years following the union with [[Lithuania]] in 1386 and the subsequent defeat of the [[Teutonic Knights]] at Grunwald in 1410. The monarchy survived many upheavals but eventually went into a decline, which ended with the final partition of Poland by [[Prussia]], [[Russia]], and [[Austria]] in 1795. | Poland's written history begins with the reign of [[Mieszko I]], who accepted [[Christianity]] for himself and his kingdom in AD 966.
