Arthur Barclay (1854-1938) served as Secretary of State of Liberia, Africa, then as its 14th President from 1904-1912. He changed the term of office from two years to four years and was re-elected three times.
Arthur's nephew, Edwin J. Barclay (1883-1955) completed the term of President C. D. B. King. Edwin was the 17th president of Liberia and had the term of office changed from four years to eight years; he was re-elected twice. He was also a poet.
Edwin Barclay and his successor were the first African heads of states to be invited to the U.S. [by President F. D. Roosevelt]. Edwin's visit to the White House marked the first time journalists from African American weekly newspapers were assigned to the White House to cover a diplomatic visit.
The Barclay family had been politically active in Liberia since the end of the 1800s; Ernest J. Barclay (d. 1894), had served as its Associate Justice of the Supreme Court and Secretary of State.
Ernest and Arthur were the sons and Edwin the grandson of former Kentucky slaves who left the U.S. during the Civil War. The family stopped in Barbados, where Edwin's father Ernest and his uncle Arthur were born, two of the many children of Anthony and Sarah Barclay. In 1865, the family moved to Africa. They were among the 300 West Indians migrating to Liberia, most of whom were from the British West Indies.
