In 1991, the Soviet Union disintegrated leading to the creation of many new States. The revolutions in the East European countries also led to many new countries being formed. All this was against communist regimes, as the people within these regions desired freedom and economic progress. Ethnic identity of various people in the region became stronger, leading to the demand for creation of new States based on ethnic identity.
Some examples of this trend are:
1. Yugoslavia split into Croatia, Serbia, Bosnia, Slovenia, etc.
2. Czechoslovakia split into Czech Republic and Slovakia in 1993.
3. Former Soviet Union disintegrated into fifteen States such as Russia, Armenia, Belarus, Ukraine, Estonia, etc.
Creation of new States based on ethnic nationalism was also seen in other parts of the world for e.g.
1. East Timor (became independent from Indonesia).
2. Eretria (became independent from Ethiopia).
3. South Sudan (became independent from Sudan).
4. Chechnya (wants independence from Russia).
