In Oct. 1945 he became head of the Church in Hungary and spoke out just as strongly against Communist oppression. He wound up back in prison for eight more years, including long periods of solitary confinement and endured other forms of torture. In 1949 he was sentenced to life in a show trial that generated worldwide condemnation.
Two weeks after the trial began in early 1949, Pope Pius XII (having failed to speak out forcefully against the Third Reich) did summon the courage to condemn what was happening to Mindszenty. Pius excommunicated everyone involved in the Mindszenty trial. Then, addressing a huge crowd on St. Peter's Square, he asked, "Do you want a Church that remains silent when she should speak … a Church that does not condemn the suppression of conscience and does not stand up for the just liberty of the people … a Church that locks herself up within the four walls of her temple in unseemly sycophancy …?"
