In the late 1800s, the Austro-Hungarian Empire (also known as the Austrian Empire until 1867) faced the greatest challenge remaining unified with a large variety of ethnic groups seeking independence within its borders. The empire was a multi-ethnic and multi-lingual entity comprising various ethnic groups, including Austrians, Hungarians, Czechs, Slovaks, Poles, Ukrainians, Romanians, Serbs, Croats, Slovenes, and others. These diverse ethnic groups had different cultural, linguistic, and political aspirations, which posed significant challenges to the empire's efforts to maintain unity and control. This internal fragmentation and the desire for independence among different ethnicities ultimately contributed to the empire's dissolution after World War I.
