Castilian (or Spanish) is the dominant language in Spain, and therefore was the language that was brought by the New World Conquistadores during the Spanish colonization of the Americas. Due to this gradual process, the Hispanophone world was created. As Castilian was the language of the Crown, it became the official language of all Spain, used side by side with other languages in their regions for centuries. During the years of the Francoist State (1939 to 1975) there was an attempt to suppress the regional languages in favour of Castilian as the sole official language, causing a backlash against the use of Castilian in some regions after his death.
