Relations between the Republic of Sierra Leone and the United States of America began with Missionary activities in the 19th century through commercial activites. The relations since then have been cordial, giving rise to the establishment of a resident Embassy in Washington DC on Thursday, April 27, 1961 at the level of Charge d'Affaires A.I. Dr. W.H. Fitzjohn served in the capacity of Charge d'Affaires A.I. until June 26, 1961 when Dr. Richard Kelfa-Caulker was appointed as Sierra Leones first Ambassador Extraordinary and Plenipotentiary to the United States of America with residence in Washington DC.
