Why did Czechoslovakia separate into the Czech Republic and Slovakia?

The separation of Czechoslovakia into the Czech Republic and Slovakia—a process known as the Velvet Divorce—was driven by a combination of long-standing ethnic tensions, economic disparities, and political deadlock following the Velvet Revolution of 1989.12

As the country transitioned from communism to a capitalist democracy, significant disagreements emerged regarding the pace of economic reforms and the structure of the federal government. The situation reached a tipping point after the 1992 elections, which brought Václav Klaus to power in the Czech Republic and Vladimir Mečiar to power in Slovakia.12

Klaus favored maintaining a strong federal government, while Mečiar sought greater sovereignty for Slovakia. Because the two leaders could not form a functional federal government and neither wished to hold a public referendum, they negotiated a peaceful dissolution. The federal legislature voted to divide the country in November 1992, and the two independent nations were formally established on January 1, 1993.12
