 Calles's term as president was coming to an end, and ex-President Álvaro Obregón had been elected president and was scheduled to take office on December 1, 1928.Obregon had been more lenient to Catholics during his time in office than Calles, but it was also generally accepted among Mexicans, including the Cristeros, that Calles was his puppet leader.Two weeks after his election, Obregón was assassinated by a Catholic radical, José de León Toral, which gravely damaged the peace process.
