Political status and violence

Since its articulation by Sabino Arana in the late 19th century, the more radical currents of Basque nationalism have demanded the right of self-determination and even independence. Within the Basque country, this element of Basque politics is often in balance with the conception of the Basque Country as just another part of the Spanish state, a view more commonly espoused on the right of the political spectrum. In contrast, the desire for greater autonomy or independence is particularly common among leftist Basque nationalists. The right of self-determination was asserted by the Basque Parliament in 2002 and 2006. Since self-determination is not recognized in the Spanish Constitution of 1978, a wide majority of Basques abstained (55%) and some even voted against it (23.5%) in the ratification referendum of 6 December that year. However, it was approved by clear majority overall in Spain (87%). The autonomous regime for the Basque Country was approved in a 1979 referendum but the autonomy of Navarre (Amejoramiento del Fuero: "improvement of the charter") was never subject to a referendum but only approved by the Navarrese Cortes (parliament).
