It remained open only as a school of philosophy and theology for the Roman clergy. On 17 January 1873 the libraries, astronomical observatory, scientific laboratory, and the Kircher Museum were taken over by the new government. With the extension of the rule of Savoy to the city of Rome, the Jesuits were finally removed. Pius IX protested against this usurpation with the encyclical "Etsi fine luctuosa" of 21 November 1873. The community of Jesuit professors found hospitality at the Palazzo Borromeo-Gabrielli as guests of the German College (moved elsewhere in 1886), now home to students of the Jesuit Bellarmine College. In this new site the school of philosophy and theology, with the official title of the Pontifical Gregorian University of the Roman College, resumed, fostered and protected by Pope Leo XIII.
