Apostle George F. Richards and Seventy's president Antoine R. Ivins begin seven days of meetings with disaffected LDS Mexicans who demand an ethnic Mexican mission president. These nationalist Mexican Mormons held the first meeting of their "Third Convention" on 26 Apr. 1936. After the failure of this general authority effort at reconciliation, church leaders on 6 May 1937 begin excommunicating dissidents. Third Conventionists foster a successful schismatic movement until 1946, when a visit of LDS president George Albert Smith to Mexico begins the process of reconciliation. The Third Convention is the first schismatic LDS movement based primarily on ethnicity and national pride.
