Ukrainian nationalism is the promotion of the unity of Ukrainians as a people and the promotion of the identity of Ukraine as a nation state. The origins of modern Ukrainian nationalism emerge during the 17th-century Cossack uprising against the Polish–Lithuanian Commonwealth led by Bohdan Khmelnytsky. Ukrainian nationalism draws upon a single national identity of culture, ethnicity, geographic location, language, politics, religion, traditions and belief in a shared singular history that dates back to the 9th century.
