The Children of Adam and Eve

Diniz, in English, Denis (1261-1325), king of Portugal (1279-1325), the
son of King Alfonso III. Diniz's reign was notable for the termination of
the wars between Portugal and the united kingdoms of L? and Castile,
achieved by intermarriage between his family and that of King Ferdinand IV
of L? and Castile; and for encouragement of Portuguese agriculture,
trade, and arts. He founded schools for the study of agriculture and
improved methods of cultivation; because of his interest in agriculture he
became known as R?avrador (the Farmer King). Diniz also made Portuguese
the language of the law courts in his kingdom. A poet himself, he was a
patron of artists and musicians and of education, establishing the
University of Coimbra (at Lisbon, 1290; moved to Coimbra, 1306). He made
(1294) a commercial treaty with England that benefited Portuguese trade
and established (1317) a royal navy. He was succeeded by his son, Alfonso
IV.
