Catalan nationalism
Catalan nationalism is the nationalist ideology which asserts that Catalans are a nation and promotes the cultural unity of Catalans.
Intellectually, Catalan nationalism can be said to have commenced as a political philosophy in the unsuccessful attempts to establish a federal state in Spain in the context of the First Republic. Valentí Almirall i Llozer and other intellectuals that participated in this process set up a new political ideology in the 19th century, to restore self-government, as well as to obtain recognition for the Catalan language. These demands were summarized in the so-called Bases de Manresa in 1892.
It met very little support at first. But after the Spanish–American War in which the United States invaded and annexed the last of the Spanish colonies, these early stages of Catalanism grew in support, mostly because of the weakened Spanish international position after the war and the loss of the two main destinations for Catalan exports (Cuba and Puerto Rico).
