Dinis' promotion of agriculture earned him the name, "The Farmer", while his love of literature, especially poetry, of which he is said to have written volumes, was perhaps his reason for establishing a university at Lisbon.
Dinis was instrumental in the growth of industry within Portugal forming a commercial treaty with King Edward I of England in 1294.
Dinis argued with the Pope that the lands occupied by the Templars did not truly belong to the order, but rather they were only granted perpetual use of the properties.
Dinis was able to prevail upon the pope to give this wealth to a newly founded Portuguese military-religious order called the Order of Christ, which was initially situated at Castro Marim but was later moved to Tomar.
Dinis chartered many settlements of colonists on lands conquered from the Muslims and authorized the holding of fairs and markets in each of these, thereby creating a national economy.
Dinis provided the impetus for the development of Portuguese as a national language when he decreed that all official documents of the realm were to be written in the vernacular.
