Its name is a tribute to the leader of the American forces of the American Revolution of 1776 and the country’s first president, George Washington. The first explorers in the region were the Spanish. It was later occupied by the British, however, these explorers did not establish any permanent settlement. Between the 1810s and 1840s, the region was the subject of dispute between the British and the Americans, until in 1846, the two countries reached an agreement. In 1848, the American province of Oregon was created, a territory that included present-day Washington, which only became a state on November 11, 1889.

Regarding its geographical characteristics, Washington is marked by contrasts: a certain region of the state is considered one of the rainiest in the world; another large part of it is quite arid. Due to the proximity to large amounts of water, temperatures in the State are quite mild: averages of 14.5ºC in summer and -1ºC in winter.

Washington’s economy is based mainly on the tertiary sector, with emphasis on the provision of community and personal services. In the industry, the State stands out in the production of airplanes, ships, software and electronic products. Major companies in these fields, such as Boeing, Microsoft and Nintendo, are headquartered in Washington. The state capital is Olympia; the largest city, economic and financial center of the same is Seattle.
