Father Ratti was a professor at the Padua Seminary from 1882 to 1888. He worked at Ambrosian Library of Milan from 1888 to 1911; and at the Vatican Library from 1911-1914.
Cardinal Ratti was elected pope on February 6, 1922; and he chose the name Pope Pius XI.
Some of his decisions were controversial. He made 18 concordats (treaties) with foreign governments. They included the Lateran Concordat with Italy in 1929; and the Reichskoncordat with Germany in 1933.
