The Constitution of the State of Washington is the document that describes the structure and function of the government of the U.S. State of Washington. The constitution was adopted as part of Washington Territory's path to statehood in 1889. An earlier constitution was drafted and ratified in 1878, but it was never officially adopted.
In 1877 Orange Jacobs, Washington Territory's Delegate to U.S. Congress, requested an enabling act that would allow Washington to become a state as soon as a state constitution was drafted and ratified by the voters. At the same time, an act was passed by the Washington Territorial Legislative Assembly to convene a constitutional convention. Without waiting for action by Congress, Washington's voters elected fifteen delegates who met in Walla Walla in June and July 1878 and drafted a constitution.
The voters of the territory approved the constitution in November 1878 with a vote of 6,537 in favor and 3,236 opposed. Congress, however, did not pass the statehood bill introduced by Jacobs. Washington Territory's next Delegate, Thomas H. Brents, also failed to get a statehood bill passed with the 1878 constitution. Later statehood bills abandoned the 1878 constitution and instead called for a state constitutional convention.
Although never approved by Congress, the 1878 constitution is an important historical document which shows the political thinking of the time. It was used extensively during the drafting of Washington State's 1889 constitution, the one and only official Constitution of the State of Washington.
In December 1888, Congress introduced an act to enable Washington, North Dakota, South Dakota, and Montana to become states. Among other requirements in the Enabling Act of 1889, Congress asked each prospective state to draft and ratify a state constitution.
