What is "donatario"

A ( Portuguese for "donated" or "endowed [one]"), sometimes anglicized as donatary, was a private person—often a noble—who was granted a considerable piece of land (a ) by the Kingdom of Portugal. The king exempted these titleholders from normal colonial administration; the donatários were comparable to a royal governor or a British Lord Proprietor. As the donataria were often captaincies, the position is also translated as captain.
