The party is a successor of the left-wing electoral alliance, the United Left. In the first parliamentary elections in 2014, we succeeded in obtaining 6 seats in the national assembly, a result that we improved to 9 MPs in 2018. The Main focus of our struggle was anti-privatisation campaigns in the context of the financial crisis, improvement of minimum wage laws and workers' protection in cooperation with trade unions, anti-imperialism and opposition to NATO membership, as well as numerous actions for protection of the environment from local to state level.

Levica's most recent campaign is aimed at stopping a 780M euros investment in the military during the pandemic.

Upon joining, Violeta Tomić, Chairwoman of the Council of The Left, said:

"We in the Left consider international cooperation one of the most important tools in the promotion of progressive ideals. We are thus happy to join Progressive international as a platform of global progressive integration, cooperation and solidarity. This form of organisation is desperately needed in times of global menace of far-right and unbridled activities of multinational corporations."
