After passage of the Ninth-of-May Constitution on 9 June 1948, the country became a People's Republic until 1960. Although it was not a completely Communist document, it was close enough to the Soviet model that Beneš refused to sign it. He'd resigned a week before it was finally ratified, and died in September. The Ninth-of-May Constitution confirmed that the KSČ possessed absolute power, as other Communist parties had in the Eastern Bloc. On 11 July 1960, the 1960 Constitution of Czechoslovakia was promulgated, changing the name of the country from the ""Czechoslovak Republic"" to the ""Czechoslovak Socialist Republic"".
