George Vancouver for Britain in 1792–1794. Lewis and Clark explored the Columbia River region and coastal areas for the U.S. in 1805–1806.

Washington has counties that no longer exist. They were established by the state, provincial, or territorial government. Most of these counties were created and disbanded in the 19th century; county boundaries have changed little since 1900 in the vast majority of states.
