Prior to the arrival of explorers from Europe, this region of the Pacific Coast had many established tribes of Native Americans, each with its own unique culture. Today, they are most notable for their totem poles and their ornately carved canoes and masks. Prominent among their industries were salmon fishing and, among the Makah, whale hunting. The peoples of the Interior had a very different subsistence-based culture based on hunting, food-gathering and some forms of agriculture, as well as a dependency on salmon from the Columbia and its tributaries. The smallpox epidemic of the 1770s devastated the Amerindian population.[14]
The first European record of a landing on the Washington coast was by Spanish Captain Don Bruno de Heceta in 1775, on board the Santiago, part of a two-ship flotilla with the Sonora. They claimed all the coastal lands up to Prince William Sound in the north for Spain as part of their claimed rights under the Treaty of Tordesillas, which they maintained made the Pacific a "Spanish lake" and all its shores part of the Spanish Empire.
In 1778, British explorer Captain James Cook sighted Cape Flattery, at the entrance to the Strait of Juan de Fuca, but the straits would not be explored until 1789, by Captain Charles W. Barkley. Further explorations of the straits were performed by Spanish explorers Manuel Quimper in 1790 and Francisco de Eliza in 1791, then by British Captain George Vancouver in 1792.
The British-Spanish Nootka Convention of 1790 ended Spanish claims of exclusivity and opened the Northwest Coast to explorers and traders from other nations, most notably Britain and Russia as well as the fledgling United States. American captain Robert Gray (for whom Grays Harbor County is named) then discovered the mouth of the Columbia River. He named the river after his ship, the Columbia. Beginning in 1792, Gray established trade in sea otter pelts. The Lewis and Clark Expedition entered the state on October 10, 1805.
Explorer David Thompson, on his voyage down the Columbia River camped at the junction with the Snake River on July 9, 1811 and erected a pole and a notice claiming the country for Great Britain and stating the intention of the North West Company to build a trading post at the site.
The UK and the USA agreed to what has since been described as "joint occupancy" of lands west of the Continental Divide to the Pacific Ocean as part of the Anglo-American Convention of 1818, which established the 49th Parallel as the international boundary west from Lake of the Woods to the Rocky mountains. Resolution of the territorial and treaty issues, west to the Pacific, were deferred until a later time. Spain, in 1819, ceded their rights north of the 42nd Parallel to the United States, although these rights did not include possession.
Negotiations with Great Britain over the next few decades failed to settle upon a compromise boundary and the Oregon boundary dispute became important in geopolitical diplomacy between the British Empire and the new American Republic. Disputed joint-occupancy by Britain and the U.S.A., lasted for several decades. With American settlers pouring into the Oregon Country; the Hudson's Bay Company, which had previously discouraged settlement because it conflicted with the fur trade, reversed its position in an attempt to maintain control of the Columbia District for Great Britain. Fur trapper James Sinclair, on orders from Sir George Simpson, Governor of the Hudson's Bay Company, guided some 200 settlers from the Red River Colony west in 1841 to settle on Hudson Bay Company farms near Fort Vancouver. The party crossed the Rockies into the Columbia Valley, near present-day Radium Hot Springs, British Columbia, then traveled south-west down the Kootenai River and Columbia River. Despite such efforts, Britain eventually ceded all claim to land south of the 49th parallel to the United States in the Oregon Treaty on June 15, 1846.
In 1836, a group of missionaries including Marcus Whitman established several missions and Whitman’s own settlement Waiilatpu, in what is now southeastern Washington state, near present day Walla Walla County, in territory of both the Cayuse and the Nez Perce Indian tribes. Whitman’s settlement would in 1843 help the Oregon Trail, the overland emigration route to the west, get established for thousands of emigrants in following decades. Marcus provided medical care for the Native Americans, but when Indian patients – lacking immunity to new, ‘European’ diseases – died in striking numbers, while at the same time many white patients recovered, they held ‘medicine man’ Marcus Whitman personally responsible, and murdered Whitman and twelve other white settlers in the Whitman massacre in 1847. This event triggered the Cayuse War between settlers and Indians.
The first settlement in the Puget Sound area in the west of what is now Washington, was that of Fort Nisqually, a farm and trading post of the Hudson's Bay Company, in 1833. Washington's erstwhile founder, the black pioneer George Washington Bush and his caucasian wife, Isabella James Bush, from Missouri and Tennessee, respectively. They led four white families into the territory and settled New Market, now known as Tumwater, Washington, in 1846. They settled in Washington to avoid Oregon's racist settlement laws.[15] After them, many more settlers, migrating overland along the Oregon trail, wandered north to settle in the Puget Sound area.
In 1852, people from all over what was to become Washington state gathered in Monticello (now Longview) to draft a memorandum to Congress. The memorandum expressed their desire to be granted statehood under the name of Columbia. This meeting came to be known as the Monticello Convention. The desires of the Convention were met favorably in Congress, but it was decided that a state named Columbia might be confused with the preexisting District of Columbia. In a manner which strangely enough did not solve the problem of being confused with the nation's capital, the state was instead named Washington in honor of the first U.S. president.[16] Washington became the 42nd state in the United States on November 11, 1889.
Early prominent industries in the state included agriculture and lumber. In eastern Washington, the Yakima River Valley became known for its apple orchards, while the growth of wheat using dry-farming techniques became particularly productive. The heavy rainfall to the west of the Cascade Range produced dense forests, and the ports along Puget Sound prospered from the manufacturing and shipping of lumber products, particularly the Douglas-fir. Other industries that developed in the state include fishing, salmon canning and mining.
For a long period, Tacoma was noted for its large smelters where gold, silver, copper and lead ores were treated. Seattle was the primary port for trade with Alaska and the rest of the country, and for a time it possessed a large shipbuilding industry. The region around eastern Puget Sound developed heavy industry during the period including World War I and World War II, and the Boeing company became an established icon in the area.
During the Great Depression, a series of hydroelectric dams were constructed along the Columbia river as part of a project to increase the production of electricity. This culminated in 1941 with the completion of the Grand Coulee Dam, the largest concrete structure in the United States.
During World War II, the state became a focus for war industries, with the Boeing Company producing many of the nation's heavy bombers and ports in Seattle, Bremerton, Vancouver, and Tacoma were available for the manufacture of warships. Seattle was the point of departure for many soldiers in the Pacific, a number of which were quartered at Golden Gardens Park. In eastern Washington, the Hanford Works atomic energy plant was opened in 1943 and played a major role in the construction of the nation's atomic bombs.
On May 18, 1980, following a period of heavy tremors and eruptions, the northeast face of Mount St. Helens exploded outward, destroying a large part of the top of the volcano. This eruption flattened the forests, killed 57 people, flooded the Columbia River and its tributaries with ash and mud, and blanketed large parts of Washington and other surrounding states in ash, making day look like night.
