The congregation lists over 90 traditional Catholic churches and chapels both in the U.S. and abroad, as well as at least 13 schools staffed by religious.

The CMRI runs a bookstore (Mary Immaculate Queen Center)[10] and produces various periodicals: The Reign of Mary (quarterly magazine), Adsum (Mater Dei seminary monthly newsletter), and Anima Mariae, the CMRI sisters' newsletter.

The CMRI also produces annual CDs of the Fatima Conference talks, as well as providing a livestream of Daily Mass and devotions from the City of Mary in Rathdrum, Idaho.

[11] Francis Konrad Maria Schuckardt (a Catholic layman from Seattle, Washington) and Robert Denis Chicoine (a former Marine, bricklayer, and newspaper pressman from New Bedford, Massachusetts) attracted their initial followers through international speaking tours as part of The Blue Army of Our Lady of Fatima.

[13] Schuckardt was ordained a priest and consecrated a bishop by Daniel Quitler Brown from 28 October to 1 November 1971 at a motel in Chicago in front of 40 witnesses.

[4] The CMRI owned and operated numerous schools, camps, and properties,[15] including a convent and girls high school in Colbert, Washington about 15 miles (24 km) north of Spokane,[16] and a mansion located at 2314 E South Altamont Blvd in Spokane, Washington that operated as the priory and Schuckardt's main residence.

[16] On June 3, 1984, Schuckardt and a small group of his followers were expelled from the CMRI and left the Spokane area, taking the name Tridentine Latin Rite Church (TLRC).

[19] In 1986, the Congregation held its first General Chapter, which established its rule and constitutions, that were later approved by sedevacantist Bishop Robert McKenna ORCM.
