After the Ottoman invasion of Hungary in the 16th century, the city was administered at various times by the Principality of Transylvania, the Ottoman Empire, and the Habsburg Monarchy. In 1598, the fortress was besieged and, on August 27, 1660, Oradea fell to the Turks and became the capital of the Varat Province. This eyalet included Varat (Oradea), Salanta, Debreçin (formerly part of Budin and Eğri Eyalets), Halmaș, Sengevi and Yapıșmaz sanjaks. The siege is described in detail by Szalárdy János in his contemporary chronicle. The city was seized by the Habsburg-led German-Hungarian-Croatian forces in September 1692.
