(called The Happy), an Italian Dominican, was born near Brescia in 1392. His family being noble and rich, allowed him to pursue his studies at Padua, where, in 1413, he assumed the habit of the Dominicans. He devoted himself to preaching, for which he showed a remarkable talent. The pestilence having broken out at Bologna, Conradin went to its relief. This city was at that time at war with the pope. Conradin, failing in bringing the citizens into submission, published an interdict which the pope had pronounced against them. He was then treated as an enemy, thrown into prison and allowed little food, but his life was wonderfully spared, and, a treaty being concluded, he was set at liberty. Conradin performed with ardor all his tasks, and, the pest again raging, he devoted himself to the sick until he himself fell a victim and died, November 1, 1429. See Hoefer, Nouv. Biog.
