The Militia of the Immaculata (MI) is a worldwide evangelization movement founded by St. Maximilian Kolbe in 1917 that encourages total consecration to the Blessed Virgin Mary as a means of spiritual renewal for individuals and society. The MI movement is open to all Catholics over 7 years old. It employs prayer as the main tool in the spiritual battle with evil. Members of the MI also immerse themselves in apostolic initiatives throughout society, either individually or in groups, to deepen the knowledge of the Gospel and our Catholic Faith and to spread devotion to the Blessed Virgin Mary.
