In response, the Knights of Columbus published posters and magazines which presented Cristero soldiers in a positive light. Ku Klux Klan In the mid-1920s, high-ranking members of the anti-Catholic Ku Klux Klan offered Calles $10,000,000 in order to aid him in his war against the Catholic insurgents, but there is no evidence that the Klan's offer was accepted. Aftermath The government often did not abide by the terms of the truce. For example, it executed some 500 Cristero leaders and 5,000 other Cristeros. Catholics continued to oppose Calles's insistence on a state monopoly on education, which suppressed Catholic education and introduced secular education in its place: "We must enter and take possession of the mind of childhood, the mind of youth." Calles's military persecution of Cristeros after the truce would be officially condemned by Mexican President Lázaro Cárdenas and the Mexican Congress in 1935. Between 1935 and 1936, Cárdenas had Calles and many of his close associates arrested and forced them into exile soon afterwards. Freedom of worship was no longer suppressed, but some states refused to repeal Calles's policy. Relations with the Church improved under President Cárdenas. The government's disregard for the Church, however, did not relent until 1940, when President Manuel Ávila Camacho, a practicing Catholic, took office. During Cárdenas presidency, Church buildings in the country continued in the hands of the Mexican government, and the nation's policies regarding the Church still fell into federal jurisdiction. Under Camacho, bans against Church anticlerical laws were no longer enforced anywhere in Mexico. The effects of the war on the Church were profound. Between 1926 and 1934, at least 40 priests were killed. There were 4,500 priests serving the people before the rebellion, but by 1934, there were only 334 licensed by the government to serve 15 million Catholics. The rest had been eliminated by emigration, expulsion, assassination, or not obtaining licenses. In 1935, 17 states had no registered priests. The end of the Cristero War affected emigration to the United States. "In the aftermath of their defeat, many of the Cristeros – by some estimates as much as 5 percent of Mexico's population – fled to the United States. Many of them made their way to Los Angeles, where they were received by John Joseph Cantwell, bishop of what was then the Los Angeles-San Diego diocese." Under Archbishop Cantwell's sponsorship, the Cristero refugees became a substantial community in Los Angeles,
