November 25, 1975, Suriname gained independence from the Netherlands.
On the same month and date 17 years later, the Federal Assembly of Czechoslovakia voted to split the country into the Czech Republic and Slovakia (officially disjoined as of January 1, 1993). This split has been called “The Velvet Divorce” (following, in style and method, “The Velvet Revolution”). The Czech Republic is now also known as Czechia.
