The Constitution of the Czechoslovak Socialist Republic (Ústava Československé socialistické / Československej socialistickej republiky in Czech / Slovak), promulgated on 11 July 1960 as the constitutional law 100/1960 Sb., was a communist state constitution and Czechoslovakia's third constitution overall. It was the second constitution adopted under Communist rule. It replaced the 1948 Ninth-of-May Constitution and was widely changed by the Constitutional Law of Federation in 1968. It was extensively revised after the Velvet Revolution to prune out its state socialist character. The revision was intended to allow the document to be used until it could be replaced with a completely new constitution. However, this never took place, and it remained in force until the dissolution of Czechoslovakia in 1992.
