The Croatian Spring, or Maspok, was a political conflict that took place from 1967 to 1971 in the Socialist Republic of Croatia, at the time part of the Socialist Federal Republic of Yugoslavia. As one of six republics comprising Yugoslavia at the time, Croatia was ruled by the League of Communists of Croatia (SKH), nominally independent from the League of Communists of Yugoslavia (SKJ), led by President Josip Broz Tito. The 1960s in Yugoslavia were marked by a series of reforms aimed at improving the economic situation in the country and increasingly politicised efforts by the leadership of the republics to protect the economic interests of their respective republics. As part of this, political conflict occurred in Croatia when reformers within the SKH, generally aligned with the Croatian cultural society Matica hrvatska, came into conflict with conservatives.
