The Idaho Constitution Convention drafted the Idaho Constitution in 1889 in preparation for the Idaho Territory to become a U.S. state.
On April 2, 1889, outgoing Territorial Governor Edward A. Stevenson, who had successfully prevented the territory from being absorbed by neighboring territories, issued a proclamation calling for an election to be held on June 3 of that year, to elect 72 delegates to a constitutional convention. On May 11, Stevenson's successor, George L. Shoup, issued a proclamation endorsing the convention, which was scheduled to meet on July 4 in Boise. Idaho, like its fellow statehood-seeking territory, Wyoming, was not the subject of an enabling act, as other statehood-seeking territories usually were before holding a constitutional convention. However, an enabling act for Idaho had been introduced in December 1888 by Oregon Senator John H. Mitchell, and its potential statehood was discussed over the remainder of the 50th Congress.
The convention met as scheduled on July 4, 1889. John T. Morgan was elected temporary president while the convention organized and settled membership disputes. The following day, William H. Clagett was elected as permanent president of the convention. On July 8, the standing committees of the convention were assigned, and from then until July 17, the committees proceeded to write the bulk of what would eventually be adopted as the state constitution. From July 18 through August 5, the convention engaged in debate over the particulars of the constitution. On the twenty-eighth day of the convention, August 6, 1889, the constitution was approved by delegates by a vote of 51âÂÂ0, and 64 of the 72 delegates (of whom one was deceased) proceeded to sign the constitution.
On November 5, 1889, Idaho Territory voters approved of the new constitution by a margin of 12,398 to 1,773. North Idaho had the strongest returns for adoption, while central and southeast Idaho had the weakest returns for adoption, with southeast Idaho falling in between. On July 3, 1890, President Benjamin Harrison signed the law admitting Idaho as the 43rd U.S. state.
Over the course of the convention, 37 committees were established. The Republican majority controlled most committees, including those that set the framework for the state government.
