Answer
Pope Pius XI beatified Bernadette Soubirous, a French peasant girl who claimed to have witnessed 18 visions of the Virgin Mary in Lourdes, France, in 1858. The beatification process involves recognizing the virtue and holiness of a person, and it is a step towards possible sainthood. Pope Pius XI declared Bernadette "Blessed" in 1925, and she was later canonized as a saint by Pope Pius XII in 1933.
