Answer
The Avignon Papacy, a seven-decade-long period when popes resided in Avignon, France, rather than Rome, concluded under Benedict XII's papacy. While he made significant contributions, such as financial reforms, the construction of the Palais des Papes, and the beatification of Thomas Aquinas, Benedict XII did not reverse the papacy's presence back to Rome, a task that would be undertaken by his successor, Pope Gregory XI.
