Cole was the grandson of a slave, and the adopted son of Reverend James Cole of Waterloo. Prior to his studies at Oxford he was educated at Fourah Bay College in Freetown, Sierra Leone. He enrolled at Oxford as a non-collegiate student with the Delegacy of Unattached Students in 1873, studying classics. Short of money, he paid his way by teaching Responsions, one of the qualifying exams for Oxford degrees, and his classes were reportedly popular. He also taught music lessons: a cartoon of the time depicts him playing a banjo. Cole's popularity at the college is indicated by the fact that when his uncle died and his financial situation worsened, fellow students and the then Master of University College, George Bradley, raised money to help him. Despite his financial problems and the disadvantages of being unattached to a college, he graduated in 1876 with a fourth-class honours degree and in November of that year was accepted as a member of University College, a position he held until April 1880. His presence drew a lot of attention, including press cartoons depicting him with racial stereotypes. His feelings about these reactions are not recorded, and he still took a very visible role in the life of the college, including speaking at the Oxford Union. According to Michèle Mendelssohn, the American abolitionist Col. Thomas Wentworth Higginson saw Cole at Oxford and described him as “a very black youth from Africa” in a B.A. gown. "King Cole" was the name that Higginson heard the undergraduates call him. On leaving Oxford in 1880 he returned to Sierra Leone, but did not find employment, so returned to England to train as a barrister. He was accepted by the Inner Temple in 1883, thus becoming the first black African practising in English courts. He later went to Zanzibar to continue his career in law. He died of smallpox in 1885, at the age of 33. Pamela Roberts, Founder and Director of Black Oxford Untold Stories, brought Christian Cole to the attention of University College Master, Sir Ivor Crewe, and the College's Governing Body with the aim of putting up a plaque to honour Cole's achievements. On 14 October 2017, Roberts and Crewe unveiled a plaque to Cole on University College's exterior wall, in Logic Lane, opposite the College’s Law Library.
Written works
Cole delivered lectures on education in Freetown, which were published in 1880. In 1879, Cole published two pamphlets. One was "What Do Men Say about Negroes?", a response to F. E. Weatherly's book Oxford Days. The other contained his thoughts on the Anglo-Zulu war and was titled Reflections on the Zulu War, By a Negro, BA., of University College, Oxford, and the Inner Temple. In the latter, he wrote: In 2006, a copy of this pamphlet, which includes two poems, was put up for sale. Former students and staff of University College donated more than a thousandpounds to buy it for the college's library, where it now resides.
