قسطنطين الحادي عشر
By the end of the 16th-century, the Ottoman Empire had become the controlling force in the region after expanding from Anatolia through Thrace to the Balkans. Many people in the Balkans place their greatest folk heroes in the era of either the onslaught or the retreat of the Ottoman Empire. As examples, for Greeks, Constantine XI Palaiologos and Kolokotronis; and for Serbs, Miloš Obilić, Tsar Lazar and Karadjordje; for Albanians, George Kastrioti Skanderbeg; for ethnic Macedonians, Nikola Karev and Goce Delčev; for Bulgarians, Vasil Levski, Georgi Sava Rakovski and Hristo Botev and for Croats, Nikola Šubić Zrinjski.
