During the constitutional meeting, it was resolved that these Fraternal Orders would found an International Alliance for the purpose of working together for the mutual advantage of the individual Member Orders and the extension of Catholic Knighthood throughout the world. Furthermore, the IACK holds its members to:

The IACK was approved as a Catholic international organization by the Holy See in 1981. By a decree dated 14 April 1992 the International Alliance of Catholic Knights was given official recognition by the Vatican as an International Catholic Association of the Faithful, in accordance with Canons 298–311 and 321–329 of the Code of Canon Law.


It was agreed that the Supreme Knight or National President of each Member Order would form an International Council which would meet annually (now biennially) and be responsible for the organization and development of the new Alliance and would provide a forum in which the leaders of the Orders could discuss matters of common concern. The Leaders present at this historic gathering are recognized as the Founders of the International Alliance of Catholic Knights.[citation needed]
