The history of the last name D�az Ruiz

The surname DIAZRUIZ is a combination of two Spanish surnames, Diaz and Ruiz. It originated in Spain during the Middle Ages, likely in the region of Andalusia in southern Spain.

The first part of the name, Diaz, is derived from the Spanish word "día," meaning "day." It was originally a patronymic surname, indicating that the bearer was the son of someone named Dia or a variation of that name. The Diaz surname can be traced back to the 9th century in Spain.

The second part, Ruiz, is also a patronymic surname derived from the Spanish name Ruy or Rodrigo, which itself comes from the Germanic name Roderick. Ruiz was a common surname in Spain during the Middle Ages, particularly in the regions of Castile and León.

One of the earliest recorded mentions of the name Diaz can be found in the Codex Calixtinus, a 12th-century manuscript from the Santiago de Compostela Cathedral in Galicia, Spain. It mentions a man named Petrus Diaz who was a member of the clergy.

In the 13th century, there is a record of a prominent Spanish nobleman named Rodrigo Diaz de Vivar, better known as El Cid, who played a significant role in the Reconquista, the Christian reconquest of the Iberian Peninsula from the Moors.

Another notable figure with the name Diaz was Bartolomé Diaz, a Portuguese explorer who in 1488 became the first European to round the southern tip of Africa, which he named the Cape of Good Hope.

Juan Diaz de Solis, a Spanish navigator and explorer, is credited with discovering the Río de la Plata (River Plate) in present-day Argentina and Uruguay in 1516.

In the 16th century, there was a Spanish conquistador named Juan Ruiz de Apodaca, who participated in the conquest of Mexico under Hernán Cortés.

While the origins of the combined surname DIAZRUIZ are not entirely clear, it likely emerged from the intermarriage of families bearing the individual surnames Diaz and Ruiz.
