Let us go in order of the history of Christianity.
Christianity started as one church. However, tensions rose and this church split into two separate churches around 1043: the Roman Catholic Church and the Eastern Orthodox Church. A second split came around the 1500s and a new branch was formed: Protestantism (splitting off Catholicism).
These three major forms of Christianity had their own area in Europe. Northern Europe was predominately Protestant. Western Europe was predominately Catholic. Eastern Europe was predominately Orthodox. The same remains today.
