How did Leo X expand the Vatican Library?

As a patron of the arts and a central figure of the Renaissance, Pope Leo X significantly increased the holdings of the Vatican Library during his pontificate.1

His efforts to expand the library were part of a broader commitment to making Rome a premier cultural center of Europe. Additionally, Leo X brought the remnants of the Medicean-Laurentian Library—a collection originally gathered by his family in Florence—to Rome after the Medici were overthrown in 1494. These manuscripts remained in his possession in Rome throughout his reign, contributing to the scholarly resources available under his papacy.213
