DELGADILLO, Diego (delgahdeel'yo), Spanish judge, born in Granada, Spain, in the latter part of the 15th century; died there in 1533. He was graduated as a lawyer at the University of Alcalg, and in 1527 appointed judge of the first audiencia or Supreme Court of New Spain. He left Seville in August and landed at Vera Cruz on 6 December 1528. Two other judges having died during the voyage, Delgadillo and Ortiz de Matienzo alone founded the audiencia in the City of Mexico. He awarded himself several repartimientos, and soon managed to send home a large amount of money; he obtained from the municipal council a grant of land, which was forbidden to the judges by the laws, and had his brother appointed governor of the Zapoteca province. Finally he declared himself in open enmity with Cortes, and opposed the missionaries and the bishops. To make himself popular among the Spatfish colonists and the natives, he founded Antequera (now Oajaca), quelled a dangerous revolt of the Indians in that province, imported the mulberry tree and the silkworm in 1530, being the first to begin their culture in the New World, and the olive tree in the following year. In the mean while his acts of mal-administration had reached their utmost, when Cortds returned from Vera Cruz, 15 July 1531, and resolved to put an end to the whole audiencia. All the judges were in accord, and intended to depose Cortes; but Archbishop Lum-Arraga succeeded in checking them. The andiencia was called to answer before other courts; 125 suits were begun, and Delgadillo, like the other members of the audiencia, was sentenced to lose all his repartimientos, and to pay 840,000 besides. He returned to Spain, and retired to his native City, where a severe illness, brought about by his troubles, ended his life.
