Question: For how many years did Alice Brown Davis serve as Principal Chief of the Seminole Tribe of Oklahoma under President Warren G. Harding?
Context: Alice Brown Davis (September 10, 1852 – June 21, 1935) was the first female Principal Chief of the Seminole Tribe of Oklahoma, and served from 1922–1935, appointed by President Warren G. Harding.  She was of Seminole (Tiger Clan) and Scots descent.  Her older brother John Frippo Brown had served as chief of the tribe and their brother Andrew Jackson Brown as treasurer. The Seminole are a Native American people originally from Florida.  Today, they principally live in Oklahoma with a minority in Florida, and comprise three federally recognized tribes: the Seminole Tribe of Oklahoma, the Seminole Tribe of Florida, and Miccosukee Tribe of Indians of Florida, as well as independent groups.  The Seminole nation emerged in a process of ethnogenesis from various Native American groups who settled in Florida in the 18th century, most significantly northern Muscogee (Creeks) from what is now Georgia and Alabama.  The word "Seminole" is derived from the Creek word "simanó-li", which may be itself be derived from the Spanish word "cimarrón", menaning "runaway" or "wild one". The presidency of Warren G. Harding began on March 4, 1921, when Warren G. Harding was inaugurated as President of the United States, and ended when he died on August 2, 1923, a span of days.  Harding, the 29th United States president, presided over the country in the aftermath of World War I.  A member of the Republican Party, Harding held office during a period in American political history from the mid–1890s to 1932 that was generally dominated by his party. George Tryon Harding II (June 12, 1843 – November 19, 1928), known as Tryon Harding (often misspelled Tyron), was an American physician and businessman who is best known as the father of Warren G. Harding, the 29th President of the United States.  He was the first presidential father to outlive his son, and the second presidential father (after Nathaniel Fillmore) to live through his son's presidency.  In his biography of Warren G. Harding, Charles L. Mee describes Tryon Harding as "a small, idle, shiftless, impractical, lazy, daydreaming, catnapping fellow whose eye was always on the main chance". The Seminole Tribe of Florida is a federally recognized Seminole tribe based in the U.S. state of Florida.  Together with the Seminole Nation of Oklahoma and the Miccosukee Tribe of Indians of Florida, it is one of three federally recognized Seminole entities.  It received that status in 1957; today it has six Indian reservations in Florida. Harry James Watson "Jimmy" Belvin was an educator and served as an Oklahoma State Representative and Senator.  He was the first elected principal chief of any of the Five Civilized Tribes in the 20th century, and the longest serving principal chief of the Choctaw Nation of Oklahoma.  He saw his tribe through termination, restoration, and a rebirth of Native Pride.  He was a polarizing leader, seen by some as a semi-dictator who held onto the office of principal chief and used his power to advocate for complete assimilation into the dominant society, suppressing Choctaw traditions, language and ceremonial practices as undesirable remnants of an unrefined history.  To others, he was a well-liked, populist leader, who went door-to-door talking with tribe members, informing them on issues, and trying to develop the means the alleviate the poverty and unemployment they faced. The Seminole Nation of Oklahoma is a federally recognized Native American tribe based in the U.S. state of Oklahoma.  It is the largest of the three federally recognized Seminole governments, which include the Seminole Tribe of Florida and the Miccosukee Tribe of Indians of Florida.  Its members are descendants of the 3,000 Seminoles who were forcibly removed from Florida to Indian Territory, along with 800 Black Seminoles, after the Second Seminole War.  The Seminole Nation of Oklahoma is headquartered in Wewoka within Seminole County, Oklahoma.  Of 18,800 enrolled tribal members, 13,533 live within the state of Oklahoma.  The tribe began to revive its government in 1936 under the Indian Reorganization Act.  While its reservation was originally larger, today the tribal jurisdictional area covers Seminole County, Oklahoma, within which it has a variety of properties. Charles Robert Forbes (February 14, 1878 – April 10, 1952) was appointed the first Director of the Veterans' Bureau by President Warren G. Harding on August 9, 1921 and served until February 28, 1923.  Caught for army desertion in 1900, he returned to the military and was a decorated World War I veteran.  He first became active in politics in the Pacific Northwest.  In 1912, Forbes moved to Hawaii and served as chairman on various federal commissions.  While Senator Warren G. Harding was on vacation in Hawaii the two met by chance and became friends.  After the 1920 U.S. Presidential election, President Harding appointed Forbes director to the newly created Veterans' Bureau, a powerful position in charge of millions of dollars in government expenditures and supplies. Warren Gamaliel Harding (November 2, 1865 – August 2, 1923) was the 29th President of the United States, serving from March 4, 1921, until his death in 1923.  At the time of his death, he was one of the most popular presidents, but the subsequent exposure of scandals that took place under his administration, such as Teapot Dome, eroded his popular regard, as did revelations of an affair by Nan Britton, one of his mistresses.  In historical rankings of the U.S. presidents, Harding is often rated among the worst. Laddie Boy (July 26, 1920 – January 23, 1929) was an Airedale Terrier owned by US President Warren G. Harding.  He was born in Toledo, Ohio.  His father was Champion Tintern Tip Top.  He was presented to US President Warren G. Harding by Charles Quetschke of Caswell Kennels and became a celebrity during the Harding administration.
