Initiative for Democratic Socialism (IDS) was a Slovenian Marxist party founded on March 8th, 2014, and was part of the United Left electoral alliance.

[1] Its collective leadership structure without an individual leader, inspired by Occupy Wall Street,[2] was conceived by members of The Workers and Punks University in November 2013, and only allowed for an elected coordinator of the IDS council.

[3] In 2017 the IDS merged with the Party for Sustainable Development of Slovenia (TRS) to form The Left(Slovene: Levica).

[4] Its program, based on The Workers and Punks University economic analysis, included regulation of neoliberalism in the short term by making tax rates more progressive, directing funds to public works to lower unemployment, and other ideas associated with social democracy.

Their long term goal was the replacement of capitalism with democratic socialism, through policies like workplace democracy and nationalization.
