From the website of the Province of St. Martin de Porres:
 

The Order of Friars Preachers, founded by St. Dominic, “is known to have been established, from the beginning, for preaching and the salvation of souls, specifically.” Our brothers, therefore, as the founder prescribed, “should everywhere behave uprightly and religiously, as men intent on procuring their own and other people’s salvation; they should behave as gospel men, following in the footsteps of the Savior, speaking to God or of God, among themselves or with their neighbors.” -from the Fundamental Constitutions.

The Order of Friars Preachers was officially approved by Pope Honorius III in 1216. Dominicans friars were formally established in the United States in 1805 by Fr. Edward Dominic Fenwick, OP. More than two hundred years later, over 850 Dominican friars are preaching the Gospel in the United States. With over 5500 friars in 70 countries throughout the world, Dominican friars continue the legacy of preaching the Gospel of Jesus Christ wherever needed, in season and out of season. Our common life of prayer, community, and study create the foundation for our preaching and service to the Church and the People of God.
