Without parliamentary representation, it is one of the microparties still active in the country with some representatives elected in the local administration (i.e. a few mayors and county councillors and 210 local councillors), especially in Râmnicu Vâlcea and Vâlcea County, where it is ranked third behind the National Liberal Party (PNL) and the Social Democratic Party (PSD), Romania's two largest parties.

The party was founded by Adrian Manolache [ro], an engineer, in January 1990 as a political organisation opposed to the National Salvation Front (FSN).

[citation needed] This party opposed the politics of the FSN from a very early stage and entered in an alliance with Radu Câmpeanu's National Liberal Party (PNL) in April, 1990, also endorsing the Timișoara Proclamation (Romanian: Proclamația de la Timișoara) which demanded that the former structures and members of the Romanian Communist Party should not get involved again in post-revolutionary politics.

[10] The first (and also founding) president of the party was Adrian Manolache, but the first party congress which was held in April 1990 elected Otto Weber as president until 2001, when he was followed by Cornel Protopopescu until 2007, the latter being subsequently replaced by Dănuț Pop.

[citation needed] In the summer of 2023, the Ecologists announced a restart for the political formation, with a new leadership and announced that they are recalibrating their public agenda in accordance with the themes of the day, from food safety to protecting the environment, in an increasingly complicated context for agriculture and environment in general.
