It began as a conflict between Protestants and Catholics in Central Europe.
there was more catholics and protestants.
Catholics didn't start Protestantism. Protestants started Protestantism and this began with Martin Luther in 1517.
Protestants are called protestants because they PROTESTED against the catholic church because Henry viii was catholic but he wanted a divorce but the catholics would not let him, so he started his own church( church of England) and they were called the protestants, also you can not be protestant and catholic.
It was a very bad thing to happen as the protestants and the catholics started to fight, and the catholics in Derry went to 1 side of the River Foyle and the protestants went to the other
A royal charter to found a colony was granted to the English Catholic nobleman, Cecil Calvert, 2nd Lord Baltimore in 1632. The earliest settlers of the Maryland colony included both Catholics and Protestants, but Catholics held the key positions in colony government.
It wasn't so much between Catholics and protestants as between Irish (who were mostly Catholic) and Englishmen (who were mostly protestant). The Irish objected to the English (and their descendants) living in their country and oppressing them, particularly as English law suppressed the Catholic faith, and the practice thereof. It made life particularly difficult for Irish Catholics for whom the practice of their faith was illegal. One of the unforeseen benefits was, that for the most part, the Catholic faith of the Irish was particularly strong, comparable to the oppressed Catholics in Poland. As the Catholics have gained ascendancy, they have started to lose their faith and become indistinguishable from other modern people.
In those days the Catholic church had spread right across Europe. Virtually all Europeans were Catholics. After Henry VIII's time the Reformation started and Protestants started to appear.
The "name change" was only made by protestants in England who thought they could be Catholics without acknowledging the Pope in Rome, they are the ones who first started referring to Catholics as Roman Catholics so as to allow themselves to be "Anglo" Catholics. There was never any official name change.
In the United States there were more Protestants than Catholics at the start of the Civil War. The great immigration of Roman Catholics to the United States came after the First Vatican Council. The Bishop of Arkansas voted No when the issue of Papal infallibility was raised. He was one of 2 Bishops to vote against the measure. For some reason a number of Catholics wanted to come to a country that had freedom of religion and where the Pope had no political power. I have no idea why.
Protestants didn't "arrive", Catholic and Protestants are both Christians, Protestant is a religion started by Martin Luther(not King just Martin Luther) who was originally a catholic but thought the Catholic ways were un-godly and not of the Bible so he started Protestant which mean Protest because they Protested against the Pope, the religion spread in mainly the north of Europe and also part of France.
The war between Irish Protestants and Catholics was known as 'The Troubles,' and was fought in both Northern Ireland, as well as the Republic of Ireland at different times. The conflict began at the end of the 1960s, and ended with the Belfast Good Friday Agreement in 1998.
