Black Legend, term indicating an unfavourable image of Spain and Spaniards, accusing them of cruelty and intolerance, formerly prevalent in the works of many non-Spanish, and especially Protestant, historians. Primarily associated with criticism of 16th-century Spain and the anti-Protestant policies of King Philip II (reigned 1556–98), the term was popularized by the Spanish historian Julián Juderías in his book La Leyenda Negra (1914; “The Black Legend”).
The Black Legend remained particularly strong in the United States throughout the 19th century. It was kept alive by the Mexican War of 1846 and the subsequent need to deal with a Spanish-speaking but mixed-race population within its borders. The legend reached its peak during the Spanish-American War of 1898, when a new edition of Bartolomé de las Casas’s book on the destruction of the West Indies was published.
