The history of the last name Aza

The surname "Aza" is believed to have its origins in the Basque region of northern Spain and southwestern France. It is thought to derive from the Basque word "aza," which means "thorn" or "bramble." The Basque people have a rich cultural heritage that dates back centuries, and their language is distinct from the romance languages spoken in the surrounding areas.

One of the earliest recorded instances of the name "Aza" can be found in the Cartulario de San Millán de la Cogolla, a medieval cartulary (collection of charters) from the monastery of San Millán de la Cogolla in La Rioja, Spain. This document, dating back to the 10th century, includes references to individuals with the surname "Aza."

In the 12th century, the name "Aza" appeared in the Becerro de las Behetrías, a medieval census of landowners and their properties in Castile. This record suggests that individuals bearing the surname "Aza" were present in the region during that time period.

One notable figure in history with the surname "Aza" was Juan de Aza (c. 1165 - c. 1230), a Spanish nobleman and member of the Order of Santiago. He played a significant role in the Reconquista, the centuries-long struggle to reclaim the Iberian Peninsula from Moorish rule.

Another individual of historical significance was Íñigo López de Aza (c. 1310 - c. 1370), a Spanish military leader and nobleman who served as the Grand Master of the Order of Alcántara, a prestigious military order in the Kingdom of Castile.

In the 16th century, Gonzalo de Aza (c. 1510 - c. 1580) was a Spanish explorer and conquistador who participated in the conquest of Peru. He was part of the expeditions led by Francisco Pizarro and Diego de Almagro.

During the 17th century, María de Aza (c. 1620 - c. 1690) was a renowned Spanish painter known for her religious works and portraits. She was active in Madrid and is considered one of the notable female artists of the Spanish Golden Age.

Lastly, in the 19th century, Ignacio de Aza (1825 - 1898) was a Spanish playwright and author who wrote numerous comedies and dramatic works that were popular during his time.
