It would be different forms of Christianity. French, Spanish, and Portuguese missionaries would spread Catholicism. British, Dutch, Swedish, Danish, and German missionaries would carry different forms of Protestant faith (such as Anglican, Methodist, Moravian, Lutheran, and Reformed).
The most important figures in spreading Christianity throughout Europe were missionaries such as St. Patrick, who evangelized Ireland, and St. Augustine of Canterbury, who played a key role in converting the Anglo-Saxons in England. Additionally, Charlemagne significantly promoted Christianity during his reign in the Carolingian Empire, enforcing its practices and supporting the Church. The efforts of these individuals, along with the establishment of monasteries and the support of various monarchs, helped to solidify Christianity's presence across the continent.
Latin Christianity became the branch of Christianity of the west because it became the Christianity of Italy and, through this, spread in the western part of the Roman Empire. It later spread throughout Western Europe. Pagan or Arian Christian Germanics invaded the empire in the west. However, the Visigoths who took over Spain and the Franks converted to Latin Christianity. The kingdom of the Franks covered Gaul and also parts of central Germany which had never been under the Romans. This helped to spread Christianity there. Charlemagne invaded northern Germany and sent missionaries to covert the pagans in that area. Another element that spread of Latin Christianity was the creation of the monastic orders. Monks became missionaries who worked throughout Western Europe. Pope Gelasius I sent missionaries to Ireland in the 490s. Pope Gregory I sent out to convert the Angles and the Saxons in England and sent missionaries there in the 590s. As for the domination of society, Medieval Europe was deeply religious. The church had a dominant presence through its influence on the populace, its links with kings and aristocrats and the pope being seen as the head of Christendom.
