How did Saint Dominic become a saint?

Dominic de Guzman founded the Order of Friars Preachers (Dominicans) in 1215, a group who live a simple, austere life, and an order of nuns dedicated to the care of young girls. He was a friend of Saint Amata of Assisi and said to have met St. Francis of Assisi. Dominic is often credited with the invention of the rosary; it actually pre-dates him, but he certainly spread devotion to it, and used it to strengthen his own spiritual life. He is said to have been a miracle worker who brought four people back from the dead.

He died on August 6, 1221, at Bologna, Italy, and was canonized July 13, 1234, by Pope Gregory IX at Rieti, Italy.
