In 1398 and 1399, Boniface IX appealed to Christian Europe in favor of the Byzantine emperor Manuel II Palaeologus, threatened at Constantinople by Sultan Bayezid I, but there was little enthusiasm for a new crusade at such a time. Saint Bridget of Sweden was canonized by Pope Boniface IX on 7 October 1391. The universities of Ferrara (1391) and Fermo (1398) owe him their origin, and that of Erfurt (in Germany), its confirmation (1392).
