The history of Washington includes thousands of years of Native American history before Europeans arrived and began to establish territorial claims. The region was part of Oregon Territory from 1848 to 1853, after which it was separated from Oregon and established as Washington Territory following the efforts at the Monticello Convention. In 1889, Washington became the 42nd state of the United States.
