Enrique de Guzmán, 2nd Duke of Medina Sidonia

Don Enrique Pérez de Guzmán y Fonseca, 2nd Duke of Medina Sidonia (d.1492), became the 2nd Duke in 1468. Born out of wedlock his birth was later legitimized by the "Reyes Católicos" Ferdinand and Isabella, and consequently the right to inherit the title. He participated in the Conquest of the Emirate of Granada, and was granted in 1478 the title of Marquis of Gibraltar. In those days, he was considered the wealthiest man in Spain.
