The Alliance of Free Democrats – Hungarian Liberal Party (Hungarian: Szabad Demokraták Szövetsége – a Magyar Liberális Párt, pronounced [ˈsɒbɒd ˈdɛmokrɒtaːk ˈsøvɛt͡ʃːeːɡɛ ˈɒː ˈmɒɟɒr ˈlibɛraːliʃ ˈpaːrt], SZDSZ [ˈɛzdeːjɛs]) was a liberal[1][2][3][4] political party in Hungary.

The party's origins lay in the illegal democratic opposition under the communist rule of János Kádár.

This gave rise to the loosely organized Network of Free Initiatives (Szabad Kezdeményezések Hálózata) on 1 May 1988 and to the foundation of the SZDSZ as an opposition political party on 13 November 1988.

[6] The party initially suggested a radical agenda for changing the political, social and economic system in the country.

However, the legitimacy of Kóka's position as party president became questioned when it was discovered that some signatures of the delegates to the assembly electing him had been forged.

In the 2010 parliamentary election, SZDSZ won only 0.25 percent of the vote and was shut out of the legislature altogether for the first time since the change of regime.

It supported same-sex marriage, euthanasia, the legalization of marijuana, higher taxes on corporations and the top 1%, lower taxes for the working class and middle class, creation of a universal basic income, increasing the minimum wage, stronger borders and eliminating illegal immigration, increasing legal immigration by 2% and ending compulsory military service.
