The Spanish Golden Age (Spanish: Siglo de Oro, Golden Century) is a period of flourishing in arts and literature in Spain, coinciding with the political rise and decline of the Spanish Habsburg dynasty. El Siglo de Oro does not imply precise dates and is usually considered to have lasted longer than an actual century. It begins no earlier than 1492, with the end of the Reconquista (Reconquest), the sea voyages of Christopher Columbus to the New World, and the publication of Antonio de Nebrija’s Gramática de la lengua castellana (Grammar of the Castilian Language). Politically, it ends no later than 1659, with the Treaty of the Pyrenees, ratified between France and Habsburg Spain. The last great writer of the period, Pedro Calderón de la Barca, died in 1681, and his death usually is considered the end of El Siglo de Oro in the arts and literature.
