What changed did not happen in most Eastern European countries with the end of cold war?

- Economic liberalization: Most Eastern European countries transitioned to a market economy, but the process was often slow and uneven. Some countries, such as Poland and the Czech Republic, were more successful in implementing economic reforms than others, such as Romania and Bulgaria.

- Political liberalization: Eastern European countries also transitioned to democracy, but this process was also often challenging. Some countries, such as Hungary and Poland, experienced significant democratic backsliding in recent years.

- Social liberalization: Eastern European countries also experienced social changes, such as the legalization of abortion and same-sex marriage. However, these changes were often met with resistance from conservative elements of society.

In summary, the end of the Cold War brought about significant changes in Eastern Europe, but the process of transition was often complex and uneven. Some countries have experienced greater success than others in implementing economic, political, and social reforms.
