In the first democratic elections in April 1990, DEMOS won 54% of the votes and formed the first multiparty government of the country, headed by the Christian Democrat Lojze Peterle. The Coalition led the process of democratization of the country, the liberalization of public life and the implementation of a market economy. The most important achievement of the Coalition, however, was the declaration of independence of Slovenia on 25 June 1991, followed by a Ten-Day War in which the Slovenians rejected Yugoslav military interference.
