Since 1893, SIM missionaries have traveled the world to fulfill the Great Commission
As was common in the nineteenth century, malaria overtook all three. Two of the men - Walter Gowans of Toronto, Canada, and Thomas Kent of Buffalo, New York - died of the fever. The third, English-born Rowland Bingham, returned to his home in Canada, ill, but still determined. Bingham made a second attempt to reach the Soudan, but once again came down with the fever and had to return home. Unable to return to Africa himself, Bingham sent out a third team. In 1902, the party successfully established a base 500 miles inland. From this base, the work of SIM began in Africa.
Also in 1893, Charles Reeves and M.E. Gavin left their homes in Australia. A Eurasian Christian from Poona, India, had come to Australia in search of missionaries to work in his home area. Reeves and Gavin answered the challenge and set sail under the name Poona and Indian Village Mission (PIVM).
In 1968, CIGM and PIVM joined to become the International Christian Fellowship (ICF). In 1907 New Zealander George Allan landed in Bolivia to minister to the Quechua Indians.
Allan's Bolivian Indian Mission grew in the years that followed to become the Andes Evangelical Mission (AEM).
In the 1980s, AEM, ICF, and SIM merged to become what was then known as SIM, the Society for International Ministries.
The most recent addition to SIM occurred in 1998 when Africa Evangelical Fellowship (AEF) merged with SIM. AEF officially began its work in Cape Town, South Africa, in 1889 as the South Africa General Mission under the leadership of Andrew Murray, Mrs. Osborne, Spencer Walton, and George Howe. Starting from urban South Africa, missionary efforts spread into many of the other countries and people groups of southern Africa.
Today's SIM missionary family is drawn from more than 50 denominations. In deciding that the mission should be interdenominational, SIM founder Rowland Bingham stated: "He is blind who does not recognize that in other denominations are some of the best saints that God and grace have made."
