Hundred Years' Croatian–Ottoman War

The Hundred Years' Croatian–Ottoman War (Croatian: Stogodišnji hrvatsko-turski rat, Stogodišnji rat protiv Turaka, Stogodišnji rat s Osmanlijama) was a sequence of conflicts, mostly of relatively low intensity ("Small War", Croatian: Mali rat), between the Ottoman Empire and the medieval Kingdom of Croatia (ruled by the Jagiellon and Zápolya dynasties), and the later Habsburg Kingdom of Croatia. Besides periods of small-scale borderland warfare, the conflict also saw episodes of major conquest campaigns of Croatian land which was undertaken by the Ottomans especially during the 16th century.
