Pope Alexander VI (Italian: Alessandro VI, Valencian: Alexandre VI, Spanish: Alejandro VI; born Roderic Llançol i de Borja; epithet: Valentinus ("The Valencian"); c. 1431 – 18 August 1503) was head of the Catholic Church and ruler of the Papal States from 11 August 1492 until his death in 1503.
Born into the prominent Borja family in Xàtiva in the Kingdom of Valencia under the Crown of Aragon (in present-day Spain), he was known as Roderic de Borja, and he is commonly referred to by the Italianized form as Rodrigo Borgia. He studied law at the University of Bologna. He was ordained deacon and made a cardinal in 1456 after the election of his uncle as Pope Callixtus III, and a year later he became vice-chancellor of the Catholic Church.
