The Ohlone culture was relatively stable until the first Spanish soldiers and missionaries arrived with the double-purpose of Christianizing the Native Americans by building a series of missions and of expanding Spanish territorial claims. The Rumsien were the first Ohlone people to be encountered and documented in Spanish records when, in 1602, explorer Sebastian Vizcaíno reached and named the area that is now Monterey in December of that year. Despite Vizcaíno's positive reports, nothing further happened for more than 160 years. It was not until 1769 that the next Spanish expedition arrived in Monterey, led by Gaspar de Portolà. This time, the military expedition was accompanied by Franciscan missionaries, whose purpose was to establish a chain of missions to bring Christianity to the native people. Under the leadership of Father Junípero Serra, the missions introduced Spanish religion and culture to the Ohlone.
