Herri Batasuna: Basque Nationalist Coalition & ETA's Electoral Arm (1978–2001)
Herri Batasuna is why Spain ultimately chose to ban a political party. At its peak it won nearly a fifth of the Basque regional vote — the most electorally successful ETA-aligned vehicle in Spain's democratic era. The 2003 ban of its successor Batasuna was the Spanish state's most consequential move to separate legal Basque nationalism from armed struggle, and it worked: ETA disbanded in 2018, while a declawed Basque left-nationalism (EH Bildu) now operates inside the system.

Herri Batasuna is why Spain ultimately chose to ban a political party. At its peak it won nearly a fifth of the Basque regional vote — the most electorally successful ETA-aligned vehicle in Spain's democratic era. The 2003 ban of its successor Batasuna was the Spanish state's most consequential move to separate legal Basque nationalism from armed struggle, and it worked: ETA disbanded in 2018, while a declawed Basque left-nationalism (EH Bildu) now operates inside the system.
Herri Batasuna ("Popular Unity" in Basque), usually abbreviated HB, was a far-left Basque nationalist electoral coalition founded in 1978 during Spain's post-Franco democratic transition. It functioned as the political arm of the armed Basque-separatist organisation ETA — endorsing its goals of an independent socialist Basque state and refusing to condemn its violence. At its peak in the 1980s and 1990s, HB regularly won 15–18% of the vote in the Basque Country and sent elected representatives to the Basque Parliament, the Spanish Congress and European Parliament — though its parliamentarians usually refused to take their seats or recognise Spanish institutions. HB was restructured into Batasuna in 2001 following legal pressure; Batasuna was banned by the Spanish Supreme Court in 2003 under the new Political Parties Law, on grounds of its links to ETA. The current Basque left-nationalist coalition EH Bildu (founded 2012) operates in the legal space opened once ETA declared a definitive ceasefire in 2011 and disbanded in 2018.
Herri Batasuna matters for two reasons. (1) It was the one case in post-Franco Spain where a party openly supporting a violent armed organisation achieved serious electoral weight — forcing the state to decide whether democratic tolerance extended to parties linked to terrorism. (2) The 2002 Political Parties Law and the 2003 Batasuna ban that followed set the Spanish template for banning parties linked to political violence, a template that shaped later debates on Catalan independence, far-right parties, and terrorism-adjacent politics across Europe.
