The name derives from the historical political party of Carlism, Traditionalist Communion [1][2][3][4][5] with the addition of Carlist (Traditionalist-Carlist), a designation occasionally used during the 1930s at the initiative of Don Alfonso Carlos.

[6] The Congress brought together three distinct political parties: Catholic-Monarchist Communion: Linked to the General Zumalacárregui Study Center of Francisco Elías de Tejada, based in Madrid.

The CTC adheres to Carlism's historic motto: “God, Fatherland, Fueros, King.” It preserves Carlist symbols, such as the Cross of Saint Andrew, the Oriamendi March, and the traditional red or white beret.

As a confessional Catholic group, the CTC bases its political action on the Church's Social Doctrine and the principle “Nothing without God.” This perspective applies a Catholic worldview to all aspects of social life, opposing:Divorce, Abortion, Euthanasia, Same-sex marriage, and Secular education in public schools The CTC defines itself as monarchist and legitimist but does not currently recognize any claimant as king.

On the other hand, the opposing faction draws inspiration from economist Daniel Marín Arribas, researcher Felisa Turuleta, and tax advisor Javier de Miguel Marqués.

On December 28, 2012, the CTC was one of the entities organizing "pro-life" rallies in several locations across Spain, including Madrid, Barcelona, Pamplona, Valencia, Valladolid, Santander, Zaragoza, Seville, Granada, and Jaén.
