What was the main cause of the breakup of the Czechoslovakia?

The main cause of the breakup of Czechoslovakia in 1993 was growing nationalistic sentiments and economic disparities between the Czech and Slovak regions. After the fall of communism, both groups sought greater autonomy, with Slovaks feeling underrepresented in the central government. The political leadership in both regions ultimately agreed that a peaceful separation would be the best solution, leading to the formation of two independent nations: the Czech Republic and Slovakia.
