O Mary, conceived without sin.
Pray for us who have recourse to you.


The Legion Of Mary was founded in Dublin, Ireland on 7th September 1921. It is a lay Catholic organisation whose members are giving service to the church on a voluntary basis in almost every country.

The object of the Legion of Mary is the glory of God through the holiness of its members developed by prayer and active co-operation in Mary’s and the Churches work.

The unit of the Legion of Mary is called a praesidium, which holds a weekly meeting, where prayer is intermingled with reports and discussion. Persons who wish to join the Legion must apply for membership in a Praesidium.


The Legion sees as its priority the spiritual and social welfare of each individual. The members participate in the life of the parish through visitation of families, the sick, both in their homes and in hospitals and through collaboration in every apostolic and missionary undertaking by the parish.

Every legionary is required to carry out a weekly apostolic work in the spirit of faith and in union with Mary.

“For all states of the laity the perfect example of spiritual and apostolic life in the most Blessed Virgin Mary, Queen of Apostles, who while leading the life common to all on earth, one filled with family concerns and labours, was always intimately united with her Son and ion an entirely unique way co-operated in the work of the Saviour……All should devoutly venerate her and commend their life and apostolate to her maternal care”.
