In 1986 a group of Trotskyists within the Italian Communist Party (PCI) in Ferrara, Emilia-Romagna started a journal named FalceMartello ("HammerSickle").
[4][5] In the run-up of the 2018 general election, the LCR joined forces with the similarly Trotskyist Workers' Communist Party (PCL) and formed a joint electoral list named For a Revolutionary Left (PSR),[6] obtaining 0.1% of the vote.
In the 2022 general election the LCR offered a "critical" support to the far-left joint list People's Union.
[8] Since the congress of the Italian General Confederation of Labour held later that year, the LCR/PCR has supported the internal component named Le Giornate di Marzo ("The Days of March").
[9][10] During its April 2024 congress, LCR decided to launch the PCR,[11] which was formally established in November 2024.
