After World War I, several new countries emerged as independent nations due to the dissolution of empires and the redrawing of borders. Notable examples include Czechoslovakia, Yugoslavia, and Poland, which regained independence after being partitioned or under foreign rule. Additionally, the Baltic states of Estonia, Latvia, and Lithuania declared independence from Russia. These changes were largely influenced by the Treaty of Versailles and other peace treaties that aimed to address national self-determination.

Nationalism was a positive feeling and drive in the 19th century when nation-states were formed and campaigns were started to become independent. Later, in the 20th century nationalism became a back of agressivity against other nations, and e.g. the Germans started to claim that their nation was superior and all the others were inferior nations. So it became rather negative.
