Context: The following tables indicate the historic party affiliation of elected officials in the U.S. state of Wyoming including: *Governors, Secretaries of State, State Auditors, State Treasurers and Superintendents of Public Instruction.  The tables also indicate the historical party composition in the: State Senate, State House of Representatives, State delegation to the United States Senate and State delegation to the United States House of Representatives.  For years in which a United States presidential election was held, the tables indicate which party's nominees received the State's electoral votes.  Prior to statehood in 1889, there were fewer elected offices, as indicated. The Blaine County Courthouse in Watonga, Oklahoma was built in 1906, the year before Oklahoma received statehood.  It has been asserted to be "one of the most imposing structures in Watonga" and it "serves as a landmark for both the town and the county," Blaine County.  It has a large central dome, a pedimented entrance, and a pediment above its cornice whose tympanum is painted with spirals and the date "1906".  Its front facade also features an arcade of three arched windows on the third and fourth story levels. This is a list of Mexican States by date of statehood, that is, the date when each Mexican State was accepted by Congress of the Union as a free and sovereign state of the Mexican Union. This list of individuals executed in New York gives the names of some of the individuals executed in New York, both before and after statehood in the United States (including as New Amsterdam), as well as the individual's date of execution, method of execution, and the name of the Governor of New York at the date of execution.  1963 marked the last execution in New York State.  Some executions recorded during the 17th and 18th centuries do not indicate the name(s) of the executed and are not, therefore, included herein. Acaena exigua is an extinct species of flowering plant in the rose family known by the common name liliwai.  It was endemic to Hawaii, where it was known from Kauaʻ i and west Maui.  It had not been seen or collected since 1957 and was feared extinct until 1997, when one plant was discovered in a remote montane bog on Maui.  The plant died in 2000, and the species is now considered extinct. Oklahoma ( ; Cherokee: "Asgaya gigageyi" / ᎠᏍᎦᏯ ᎩᎦᎨᏱ; Pawnee: "Uukuhuúwa", Cayuga: "Gahnawiyoˀgeh") is a state in the South Central region of the United States.  It is the 20th-most extensive and the 28th-most populous of the 50 United States.  The state's name is derived from the Choctaw words "okla" and "humma", meaning "red people."  It is also known informally by its nickname, "The Sooner State," in reference to the non-Native settlers who staked their claims on the choicest pieces of land before the official opening date and the Indian Appropriations Act of 1889, which opened the door for white settlement in America's Indian Territory.  The name was settled upon statehood.  Oklahoma Territory and Indian Territory were merged and Indian was dropped from the name.  On November 16, 1907, Oklahoma became the 46th state to enter the union.  Its residents are known as "Oklahomans," or informally "Okies", and its capital and largest city is Oklahoma City.

Hawaii is the only U.S. state located in Oceania and the only one composed entirely of islands.  It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean.  Hawaii is the only U.S. state located outside North America. The following is a list of mountain passes and gaps in California.  California is geographically diverse with numerous roads and railways traversing within its borders.  In the middle of the U.S. state lies the California Central Valley, bounded by the coastal mountain ranges in the west, the Sierra Nevada to the east, the Cascade Range in the north and the Tehachapi Mountains in the south.  Although most of these passes are now traversed by state highways, some date prior to California's statehood in 1850 and are today registered as California Historical Landmarks. Simon Bamberger (February 27, 1845October 6, 1926) was the fourth Governor of Utah (1917–1921) after it achieved statehood from territorial status in 1896.  Bamberger retains the distinction of being the first non-Mormon, the first Democrat, as well as the first, and to date only, Jewish Governor of Utah.  He was also the third Jew ever elected governor of any state, after Washington Bartlett of California and Moses Alexander of Idaho. Martha Maria "Mattie" Hughes Cannon (July 1, 1857 – July 10, 1932) was a Welsh-born immigrant to the United States, a polygamous wife, physician, Utah women's rights advocate and suffragist, and Utah State Senator.  Her family immigrated to the United States as converts to the Mormon church and traveled West to settle in Utah territory with other Mormons.  She started working at the age of fourteen.  At sixteen she enrolled in the University of Deseret, now called the University of Utah, receiving a Bachelors in Chemistry.  From there she attended the University of Michigan and received her MD.  She became the fourth of six wives in a polygamous marriage to Angus M. Cannon, a prominent Mormon leader during the anti-polygamy crusade.  Cannon exiled herself to Europe so she wouldn't have to testify against her husband.  Upon returning to Utah, Cannon worked as a doctor and fought for women's rights.  She helped put women enfranchisement into Utah's constitution when it was granted statehood in 1896.  On November 3, 1896 Cannon became the first female State Senator elected in the United States, defeating her own husband, who was also on the ballot.  Martha Hughes Cannon was the author of Utah sanitation laws and was a founder and member of Utah's first State Board of Health.
