Montejurra
Montejurra in Spanish and Jurramendi in Basque are the names of a mountain in Navarre region ( Spain). Each year, it hosts a Carlist celebration in remembrance of the 1873 Battle of Montejurra during the Third Carlist War. In 2004, approximately 1,000 persons turned out.
On 9 May 1976 during the Spanish Transition, far right-wing gunmen supported by the Spanish secret services, killed two people at the Carlist Party celebration at a time when it was drifting toward left-leaning positions. This became known as the Montejurra Incidents.
