Answer :

The division between the Catholic countries and the Protestant countries was seen in the religious colonies and missionaries  that came to the New World. The colonies settled by English, Dutch, German had more tendency to be Protestant (Anglican, Puritan, Pilgrim, French Hugenout, Baptist). Many of these were located along the eastern seaboard from Maine to Georgia and inward to Southern states such as the Tennessee, Mississippi, Alabama and parts of Louisiana. The Spaniards and Catholic French made their settlements along the St. Lawrence River and in the Canadian areas. Much of the Great Lakes area were Catholic due to the French culture. The Spaniards settled Florida, New Orleans and Mexico area which extended into much of the western US at that time. Catholic missionaries had missions throughout Mexico, California,Arizona, New Mexico and some farther north. South America had a far greater Catholic population because of the Spanish and Portuguese influence. When people began to move out of the original colonies to make new towns then both  the religions were present and new ones developed.
