Party was created by a broken-off fraction of the Democratic Party (DS) in the aftermath of the 2012 elections after which president Boris Tadić lost to his opponent Tomislav Nikolić and inner arguments maintaint on resulting in early party elections and Tadic's withdrawal from the leadership, settling for an honorary presidential title, in favor of Belgrade mayor Dragan Đilas. A total of 7 MPs left the DS and founded in 2012 the "Together for Serbia" parliamentary club. Its leader is former minister Dušan Petrović.
In 2018, the Party was one of the founding members of the big tent opposition coalition called the Alliance for Serbia (SzS).[8][9][10] The alliance announced the 2020 Serbian parliamentary elections.[11] In May 2019 ZZS formed a union with Democratic Party (DS) and Tadić's SDS. On 23 February 2020, Together for Serbia announced that they will participate in the 2020 elections on local (municipal) level, shortly after that Alliance for Serbia's leadership commented that Together for Serbia disqualificated itself from the coalition.[12]
The party keeps close ties and cooperates with the centre-left Do not let Belgrade drown (NDB),[13] and it has previously had ties with the centrist Civic Democratic Forum (GDF).[14][15] In July 2021, ZZS announced that it applied for membership to the European Green Party.[16] The leader of ZZS, Nebojša Zelenović, announced the formation of "Action", a political group built around 28 environmental civic groups that support the "Green Agreement of Serbia", in June 2021.[17] Later during the environmental protests in November, Zelenović, Dobrica Veselinović, leader of the NDB and Aleksandar Jovanović Ćuta, environmental activist and de facto leader of the protests, have announced the formation of a joint list for the upcoming general elections and Belgrade City Assembly election.[18][19] The media dubbed the coalition as "Green-Left bloc".[18][20] The formation was finalized on 19 January, when it was announced to the public that the coalition has been officially formed.[21][22]
