Macedonian nationalism (Macedonian: Македонски национализам, romanized: Makedonski nacionalizam, pronounced [makɛdonski nat͡sionalizam]) is a general grouping of nationalist ideas and concepts among ethnic Macedonians that were first formed in the late 19th century among separatists seeking the autonomy of the region of Macedonia from the Ottoman Empire. The idea evolved during the early 20th century alongside the first expressions of ethnic nationalism among the Slavs of Macedonia. The separate Macedonian nation gained recognition after World War II when the "Socialist Republic of Macedonia" was created as part of Yugoslavia. Afterwards the Macedonian historiography has established historical links between the ethnic Macedonians and events and Bulgarian figures from the Middle Ages up to the 20th century. Following the independence of the Republic of Macedonia in the late 20th century, issues of Macedonian national identity have become contested by the country's neighbours, as some adherents to aggressive Macedonian nationalism, called Macedonism, hold more extreme beliefs such as an unbroken continuity between ancient Macedonians (essentially an ancient Greek people), and modern ethnic Macedonians (a Slavic people), and views connected to the irredentist concept of a United Macedonia, which involves territorial claims on a large portion of Greece, along with smaller regions of Albania, Bulgaria, Kosovo and Serbia.
