A commission was established in 1929 by Pius XI to draw up a schema for an Oriental Catholic canon code,[1][2] the Commissionem Cardinalitiam pro Studiis Praeparatoriis Codificationis Orientalis.

[3] In 1935, the same pope established another commission with the same goal, the Pontificia Commissio ad redigendum Codicem iuris canonici orientalis, to replace the former.

[8] After World War II, a new situation developed as millions of united Christians from Eastern Europe and the Middle East emigrated to the West: United States, Western Europe, Canada, South America, and Australia.

Traditionally, Eastern Christians insisted on legal exemptions, allowing them to keep most of the ancient customs and laws.
