Dominic (1170-1221) is best known for founding the Dominicans, also known as the Order of Preachers or the Black Friars. He was born in Spain, received an extensive education, and joined the Augustinians. While traveling on a diplomatic mission to France as a Bishop's Chaplain he was introduced to the Albigensians, or Cathari, individuals who were considered heretics. The priest dedicated the next period of his life to educate these people on true Christianity and change their beliefs. His missionary model sought to emulate the original twelve disciples, walking everywhere they went, preaching as often as possible, living in charity and faith.
In 1215 Dominic created a new order that traveled to wherever there was need, focused on intellectual studies of doctrine and theology and met their needs by begging.
On his death bed, Dominic exhorted his fellow priests to practice charity, be humble, and continue to live in voluntary poverty. When he was declared a saint in 1234, the pope called him "a man of the gospel in the footsteps of the Redeemer."
Dominic is the patron saint of the Dominican Republic and astronomers.
