April 17, 1708: Ambrose, Archbishop of Moscow from 1768-1771 is born.

April 17, 1937: With Mussolini's troops occupying Ethiopia, Sudan Interior Mission missionaries who had started a small church among the previously devil-worshiping Wallamo tribe are forced to leave the country.

The missionaries returned in July 1943 to find that, despite severe persecution by Italian soldiers, the Christian community had grown from 48 members to 18,000.
