views of centralism, inherited from Franco's regime, and those who viewed Spain as a "nation of nations". In the second article, the constitution recognizes the Spanish nation as the common and indivisible homeland of all Spaniards, integrated by nationalities and regions. In practice, and as it began to be used in Spanish jurisprudence, the term "nationalities" makes reference to those regions or autonomous communities with a strong historically constituted sense of identity or a recognized historical cultural identity, as part of the indivisible Spanish nation. This recognition, and the process of devolution within the "State of Autonomies" has led to the legitimation of the Spanish state among the "nationalities", and many of its citizens feel content within the current status quo. Nonetheless, tensions between peripheral nationalism and centralism continue, with some nationalist parties still advocating for a recognition of the other "nations" of the Spanish Kingdom or for a peaceful process towards self-determination.

Initially ETA targeted primarily Spanish security forces, military personnel and Spanish Government officials. As the security forces and prominent politicians improved their own security, ETA increasingly focused its attacks on the tourist seasons (scaring tourists was seen as a way of putting pressure on the government, given the sector's importance to the economy) and local government officials in the Basque Country. The group carried out numerous bombings against Spanish Government facilities and economic targets, including a car bomb assassination attempt on then-opposition leader Aznar in 1995, in which his armored car was destroyed but he was unhurt. The Spanish Government attributes over 800 deaths to ETA during its campaign of terrorism. On 17 May 2005, all the parties in the Congress of Deputies, except the PP,
