The Union of Democratic Forces (Bulgarian: Съюз на демократичните сили, romanized: Sayuz na demokratichnite sili, СДС/SDS) is a political party in Bulgaria, founded in 1989 as a union of several political organizations in opposition to the communist government. The Union was transformed into a single unified party with the same name. The SDS is a member of the European People's Party (EPP). In the 1990s the party had the largest membership in the country, with one million members,[12] but has since splintered into a number of small parties totaling no more than 40,000 members. The SDS proper had 12,000 members in 2016.[1]
