The first opposition groups in Croatia were set up as civic associations in 1989. The first among them was the Croatian Social Liberal Union (—HSLS), which was founded on 20 May 1989 and was later renamed the Croatian Social Liberal Party. The Croatian Democratic Union (—HDZ), which would later become the main opposition to the SKH, was founded on 17 June 1989 but was registered on 25 January 1990. The HDZ held its first convention on 24–25 February 1990, when Franjo Tuđman was elected its president. On 1 March 1990, the Coalition of People's Accord (—KNS) was formed as an alliance of the Croatian Christian Democratic Party (—HKDS), the Social Democratic Party of Croatia (—SDSH), the Croatian Democratic Party (—HDS), the HSLS and five independent candidates; Savka Dabčević-Kučar, Ivan Supek, Miko Tripalo, Dragutin Haramija and Srećko Bijelić, who were prominent figures of the 1971 Croatian Spring political movement.
