市民フォーラム
The party was founded in 1991 as one of two successors to the Civic Forum, which was a big tent movement that consisted of two major wings. The strongest wing was the Interparliamentary Club of the Democratic Right which was transformed into the ODS when Civic Forum split. ODS represented followers of Václav Klaus and was pro-free market, as opposed to the centrist Civic Movement. An agreement was reached to split the party in half at the Civic Forum Assembly on 23 February 1991. This was followed on 21 April by a formal declaration of a new party, and Klaus was elected its first President. The party agreed to continue in a coalition government with the Civic Movement, but this collapsed in July 1991.
