The history of the last name Iza

The surname IZA has its origins in the Basque region of northern Spain and southwestern France. It is believed to have derived from the Basque word "iza," which means "to be" or "to exist." The name likely originated in the medieval period, around the 10th or 11th century.

One of the earliest recorded instances of the surname IZA can be found in a 12th-century document from the town of Pamplona, in the former Kingdom of Navarre. The document mentions a person named Lope Iza, who was a landowner in the region. This suggests that the name had already become established as a surname by that time.

In the 13th century, the name appeared in several records from the Basque provinces of Gipuzkoa and Bizkaia. For example, in 1265, a man named Juan Iza was listed as a witness in a legal document from the town of Azpeitia. There are also references to a family bearing the name Iza in the town of Bermeo during this period.

During the 14th and 15th centuries, the surname IZA continued to be prevalent in the Basque region, with several notable individuals bearing the name. One such person was Pedro Iza, a merchant from Bilbao who lived in the early 15th century and was involved in trade with England and the Netherlands.

In the 16th century, the name Iza appeared in records from the Basque Country and other parts of Spain. For instance, in 1542, a man named Juan Iza de Mondragon was appointed as a judge in the city of Seville. Another notable figure was Martín Iza, a soldier who fought in the Spanish conquest of the Inca Empire in Peru during the 1530s.

As the centuries passed, the surname IZA spread beyond the Basque region, with individuals bearing the name appearing in various parts of Spain and Spanish colonies. One notable example is Miguel Iza y Eslava, a Spanish military officer and writer who lived in the late 18th and early 19th centuries. He fought in the Peninsular War against the French and wrote several works on military tactics and strategy.

Other individuals with the surname IZA include José Iza Zamácola, a 19th-century Spanish historian and writer from Bilbao, and Martín Iza Aguirre, a Basque politician and lawyer who served as a deputy in the Spanish parliament in the early 20th century.
