[1][2] It was founded in April 2018 by mayor of Parma Federico Pizzarotti, other former members of the Five Star Movement and local non-party independent politicians generally affiliated with the centre-left coalition.

[6] In April 2018, Pizzarotti launched Italia in Comune,[7][1][8] which aimed at becoming the collector of local "civic lists", as well as disgruntled former M5S members.

The party was co-founded by Alessio Pascucci, a left-wing independent who had been elected mayor of Cerveteri, Lazio in 2012 and 2017, supported by civic lists and the Federation of the Greens (FdV).

[9][10] In October 2018, Serse Soverini, a member of the Chamber of Deputies elected in the 2018 general election as a representative of Civic Area, a minor progressive party close to Romano Prodi, joined IiC[11] and soon became the party's regional coordinator in Emilia-Romagna, the region of Parma and, consequently, IiC's powerbase.

[12] Almost a year later, in September 2019, after Matteo Renzi had left to form Italia Viva, Soverini would leave IiC too and join the Democratic Party.
