In the article, the authors illustrate a brief development of Slovenia from the formation of the first associations/parties in 1988 to the April elections of 1990. In the spring of 1988, the first two political organizations of the fledgling opposition were formed within old structures, as a legislation that would formally allow for the formation of parties was yet to be adopted. An act which formally established a multi-party system was adopted together with the Elections Act in late December 1989. Prior to the elections, the old tricameral parliamentary system was preserved. In April 1990 the first multi-party elections were held, i.e. elections of the president of the Presidency and members of the Presidency. The new Assembly convened in May 1990 and elected the first multi-party government, which was led by Lojze Peterle. Milan Kučan was elected President of the Presidency.
