Powell Foulk Clayton (August 7, 1833 – August 25, 1914) was an American politician, diplomat, and businessman who served as the 9th governor of Arkansas from 1868 to 1871, as a Republican member of the U.S. Senate for Arkansas from 1871 to 1877 and as U.S. Ambassador to Mexico from 1897 to 1905. During the American Civil War, he served as a senior officer of United States Volunteers and commanded cavalry in the Trans-Mississippi Theater. After the war, he married a woman from Arkansas, purchased a plantation and settled in Jefferson County. He was active in the Arkansas Republican party and became governor after military rule was lifted and the Arkansas state constitution was ratified by Congress. He was viewed as a carpetbagger and implemented martial law in Arkansas for four months due to the rise of the Ku Klux Klan and violence against African-Americans and Republicans. The Arkansas Republican party splintered during Clayton's governorship. Clayton and his followers were known as Minstrels and a more conservative faction led by Joseph Brooks were known as Brindletails. The power struggle between the groups resulted in the impeachment of Clayton in 1871 and the Brooks-Baxter War. Clayton was elected to the U.S. Senate for Arkansas in March 1871. A U.S. Senate Joint Select Committee investigated him for claims made by his political rivals that he issued fraudulent election credentials during his time as governor. He was acquitted of these charges and returned to Arkansas after losing his Senate seat in 1877 when Democrats took control of the Arkansas legislature. He remained active in the Republican National Committee and helped William McKinley receive the Republican nomination for president in 1896. He was rewarded for his support of McKinley with an assignment as Ambassador to Mexico. In 1882, Clayton established a home in the developing resort town of Eureka Springs, Arkansas. He was president of the Eureka Springs Improvement Company and worked to develop commercial and residential properties. In 1883, he became president of the Eureka Springs Railroad which provided rail service to the developing community. He died in Washington, D.C. in 1914 and was interred at Arlington National Cemetery.
