Polish-Ottoman War

The Polish-Ottoman War was a war between Poland and the Ottomans over Lesser Poland and Galicia-Volhynia.

Background
The Ottomans have been expanding everywhere for a long time, and in Europe have successfully taken eastern Hungary (i.e. Transylvania) and southern Austria. Their next target would be Poland, who was strong but not strong enough. Their allies England and Sweden were already fighting in the Transatlantic War, and only the latter nominally joined the war against the Ottomans.

The War
War was declared on 8 October 1589. Poland took the initiative and besieged Zemplen. The Polish took the initiative and besieged Zemplen in Ottoman-owned Slovakia. The fortress fell on 19 April 1590, after which the Poles targeted Dalmatia. It took until August for the Ottomans to properly counterattack and attempt to retake Zemplen, and even then only a force of 13,000 men were sent, a small amount compared to their massive army.

Poland also attacked Crimea and occupied lands the latter took from Lithuania in the Lithuanian-Crimean War. During this time of distraction, the small 13,000-strong force - which was led by the extremely talented general Numan Abaza - besieged Warsaw itself. They were terribly defeated though, a shock to the Ottoman government.

Crimean troops besieged Podole but were attacked by Polish and Swedish troops. The combined forces then attacked the Crimeans again in neighboring Bratslav, ending in a decisive victory. Just afterwards though, the main Ottoman force attacked them, and the Poles and Swedes were forced to retreat to Drakestad.

Nogaian troops invaded Polish Russia, specifically Ryazan, but retreated due to the advancing Polish armies. Ottoman troops renewed their invasion of Galicia-Volhynia, and Crimea attacked Polish Russia again. Swedish troops, who were hiding in Nya Stockholm, retreated to Sweden proper. The Ottomans continued their invasion and occupied Warsaw on 22 December 1592.

By the time the Transatlantic War ended, the Ottomans had occupied more than half of Poland proper and Polish Russia. Polish troops attacked the Ottomans at Osterode on 20 September 1593, but they were beaten, with Polish general Igor Lubranski being killed. Ottoman troops then besieged Nya Stockholm, which fell after just two months on 27 November. Other forces led by Seyfeddin Oruc attacked Swedish Pomerania and Livonia. Polish troops did attempt to take back their lands, but Aleksander I famously said regarding this that "It's just a lost cause".

End
The Treaty of Constantinople was signed on 15 March 1595, which ended the Polish-Ottoman War. Poland had to cede Przemysl and Nowy Sacz to the Ottomans. They also had to give Kuma, Kudak, Tyn, Tichorieck, Lower Don, and Bachmut to Crimea.
