The life of Saint Dominic is a synopsis of a 12th-century Spanish priest who founded the Order of Preachers (Dominicans) to combat the Catharism heresy in Southern France, emphasizing the importance of preaching, prayer, poverty, study, and using the Rosary as a primary tool of evangelization. Born into a noble family, Dominic was known for his intelligence, spiritual devotion, and simple lifestyle, which inspired many followers and led to the founding of the order that spread throughout Europe, making it one of the most influential religious orders in the Catholic Church.
