The Polish–Turkish War of 1485-1503 was a prolonged conflict, rather a series of conflicts, between the Kingdom of Poland and the Ottoman Empire. The conflict formally lasted eighteen years, but during this time hostilities were ceased on several occasions due to temporary treaties being signed between the warring parties. The climax of the conflict was the disastrous King John I Albert’s raid on Moldavia (1497, see also Battle of the Cosmin Forest).
