The Burgos trials (Spanish: Proceso de Burgos) were a series of military tribunals held in the Spanish city of Burgos from 3 to 9 December 1970. The trials prosecuted 16 members of the Basque separatist organisation Euskadi Ta Askatasuna (ETA) for their involvement in two murders of police officers in 1968. Causing international outrage and sympathy for the defendants, the trials are best known for six death sentences handed out by the tribunals which were later commuted to lengthy prison spells.
