Republican Left of Catalonia

The Republican Left of Catalonia (Catalan: Esquerra Republicana de Catalunya, ERC; IPA: [əsˈkɛrə rəpubːliˈkanə ðə kətəˈluɲə]; generically branded as Esquerra Republicana) is a pro-Catalan independence, social-democratic political party in the Spanish autonomous community of Catalonia, with a presence also in Valencia, the Balearic Islands and the French department of Pyrénées-Orientales (Northern Catalonia). It is also the main sponsor of the independence movement from France and Spain in the territories known as Catalan Countries, focusing in recent years on the creation of a Catalan Republic in Catalonia proper. Its current president is Oriol Junqueras and its secretary-general is Marta Rovira. The party is a member of the European Free Alliance.

ERC, a party of relevant Catalan politicians including Francesc Macià, Lluís Companys and Josep Tarradellas, played an important role in Catalan and Spanish politics during the Second Republic, the Civil War, the anti-Francoist resistance and the transition to democracy. Recovering a key position during the 2000s, it became a coalition partner in various Catalan governments, obtaining in 2021 the presidency of Catalonia for the first time since 1980 after the appointment of Pere Aragonès as President of the Generalitat. In 2022, it had 9,047 members.
