## History
### Ancient history

The Sobalvarro surname first appeared in the Basque regions of Spain. Because the Basque were the last remnants of the older Western Europe, the last name became known when there was conflict inside of Spain. The Basque tribes were mentioned by Strabo and Pliny as early as the 2nd century B.C. Stories of heroic acts by Sobalvarros are told by the Vascones and the Aquitani in the languages of Aquitaine, Basque, and Iruña-Veleia. These languages were already present in the area when the tribes began to migrate to the north-west from southern and southwestern present-day Europe.

### Middle Ages

The name survived the Middle Ages even when Muslims and Franks fragmented the territory. Previous to this invasion, there was a coat of arms present in battles serving under the Castilian noblesse. The Sobalvarro name then began to expand within the newly formed Kingdom of Castile and Kingdom of Pamplona.
In the early to mid-15th century, influences from Aragonese, Castilian, and French neighbors began to cause feuds for the Navarre region. Once all of the feuds were settled, Navarre was eventually divided into pieces that neighboring countries and kingdoms annexed. The southernmost area that was not annexed was given as part of a treaty to France. This was the 1662 French Treaty of Devolution, during the War of Devolution, under the reign of Phillip IV. The treaty was proposed and constructed by Jean Sobalvarro. The self-governing Basque gave him the power to negotiate alongside the French to prevent the area from engaging in violence. The country continuously struggled to state its own independent country.
The surname later spread throughout France and Spain and into parts of Italy.

### Present day
