The history of the last name Justo

The surname Justo has its origins in Spain, where it is believed to have emerged during the medieval period. The name is derived from the Latin word "justus," meaning "just" or "upright," suggesting that it may have initially been used as a descriptor for someone considered to be a fair or righteous person.

This surname can be traced back to the early 13th century, as evidenced by records from the region of Castile, where variations such as Juste and Justo appeared in historical documents. It is likely that the name spread throughout the Iberian Peninsula during the subsequent centuries, as Spain experienced periods of expansion and cultural exchange.

One of the earliest known references to the surname Justo can be found in the Libro de la Montería, a 14th-century manuscript commissioned by King Alfonso XI of Castile, which contains the name of a nobleman named Rodrigo Justo. This document serves as a valuable historical record, shedding light on the presence of this surname in medieval Spain.

The name Justo has been associated with several notable individuals throughout history. In the 16th century, Juan Justo, a Protestant theologian born in Castile, played a significant role in the Reformation movement in Spain. Another prominent figure was Fray Juan de Justo, a Spanish Franciscan friar and historian who lived in the late 16th and early 17th centuries.

During the 17th century, the name Justo gained prominence in the arts, with the renowned Spanish painter Juan Bautista Martínez del Mazo Justo (1612-1667) becoming a prominent figure in the Spanish Golden Age of art. His works, which include portraits and religious scenes, can be found in prestigious museums and collections around the world.

In the realm of literature, the 19th century saw the emergence of the Spanish writer and poet Juan Francisco Vásquez Justo (1833-1898), whose works explored themes of love, nature, and the human condition.
