i dont knows
why did the spanish first send a expedition to alta california in the 1500
The Spanish did.
Sebastian Vizcaino was the first to make a detailed map of the California coastline and consequently was responsible for naming various sites such as the bays of San Diego and Monterey, and Santa Catalina Island, among others. Vizcaino's journey began in 1602 and as an unforeseen consequence led to the exploration of the Oregon coast when one of his ships became separated from the group. Notes: San Diego was the name of Vizcaino's flagship while mapping the coast. The Count of Monterrey was the Spanish Viceroy who assigned him to map the coastline.
He was an explorer, Spanish by birth and working for Spain.
Vizcaino is not a pirate. He was an explorer for the Spanish exploration commite in the 1600s. He was not a pirate and did not have anything to do with the English pirater ship. However, he did sail.
Some Spanish explorers are Balboa, Cortes, Pizarro, Vizcaino, and Columbus (an Italian sailing Spanish ships).

Americans were increasing their interest in an even more distant province of Mexico: California. In vast region lived members of several western Indian tribes and perhaps 7,000 Mexicans, mostly descendants of Spanish colonists.
The Spanish wanted riches such as gold and silver.
