Uruguay experienced a period of targeted attacks and intimidation by the Basque separatist group ETA during the 1980s, a largely overlooked aspect of the organization’s European operations. These actions included takeovers and threats, revealing a lesser-known facet of ETA’s international reach. The incidents coincided with political pressure exerted by then-Spanish Prime Minister Felipe González on Uruguayan President Luis Alberto Lacalle Herrera. Reports suggest the involvement of armed “internationalists” and the misuse of a stolen seal in facilitating these activities. The nature of this pressure and the motivations behind targeting Uruguay remain points of historical scrutiny. This period highlights the complex interplay between Spanish domestic politics and Uruguay’s sovereignty during a turbulent era for both nations. The events demonstrate ETA’s willingness to extend its operations beyond Spain’s borders.
