The Catholic Church has a history that spans over two thousand years, and it began with none other than Jesus Christ himself. At least, that is what modern popes believe. But at first, there was just one church, and there was no division between Catholics, Protestants, Eastern Orthodox, and other branches of Christianity. Christians all over the known world were united, and together, they made their spirituality bloom. Their religion took over the lives of villagers, nobles, kings, queens, and even newly-arrived pagan armies that came to conquer Europe.
