FOOTNOTES:
Pedro Gonzalez de Mendoza (born 3 May 1428, died 11 January 1495) was a Spanish cardinal and statesman, born into the noble family of Lopez de Mendoza, marquesses of Santillana, Spain. He was chosen by King John II to be bishop of Calahorra in 1452, and accepted the Pope's bulla in 1454. As bishop he was also civil and military ruler of the town and its territory, and led the army of Calahorra in the civil wars of the reign of King Henry IV. In 1473 Mendoza was raised to the rank of cardinal, promoted to the archbishopric of Seville and designated chancellor of Castile. During the conquest of Granada, he contributed to the support of the army, and in January 1492 he occupied the town in the name of the Catholic rulers of Spain. Although more of a soldier and statesman than cleric, the 'Great Cardinal' fulfilled his role as a bishop who used his influence with the royal court and in Rome to settle disputes between the Spanish sovereigns and the Vatican. As an archbishop, Mendoza lived stylishly, provided for his many children, and devoted part of his income to charity. He endowed the college of Santa Cruz at Valladolid University, was an advocate of Christopher Columbus at court and was instrumental in securing financial support for the explorer's trans-Atlantic voyage. Archbishop Mendoza fell ill late in 1493/4 and died a year later. His biography was written by Salazar de Mendoza under the title Cronica del gran cardinal Don Pedro Gonzalez de Mendoza, and published in Toledo in 1625.
