Christianity and the Catholic Church in the High Middle Ages
This essay examines the central role that Christianity and the Roman Catholic Church played in shaping political relationships, warfare, and notions of authority during the High Middle Ages. Drawing on primary sources—including Urban II's 1095 Council of Clermont speech, William of Tyre's History, Gunther of Paris's account of the sack of Constantinople, and Pope Innocent III's rebuke of Crusader conduct—the paper argues that the Church served both as a unifying force for European Christendom and as an institution vulnerable to human corruption. The essay traces how religious faith motivated military service and political loyalty while also acknowledging how warfare could distort Christian purpose, as illustrated by the theft of holy relics.

What makes this paper effective
- Makes consistent and direct use of primary sources, quoting them accurately and explaining their relevance to the argument rather than simply citing them for decoration.
- Balances two sides of the Church's influence—its unifying, spiritual function and its vulnerability to human corruption—giving the argument genuine analytical tension.
- The concluding paragraph ties the paper's key examples back to a clear thesis about the gap between religious ideal and human practice, leaving a strong final impression.
Key academic technique demonstrated
The paper demonstrates effective use of primary-source evidence to support a historical argument. Rather than summarizing what historians say about the Church, the writer lets figures like Urban II, Innocent III, Gunther of Paris, and William of Tyre speak directly, then interprets each quotation in relation to the central claim. This technique—quote, context, analysis—is the foundation of evidence-based historical writing at the undergraduate level.
Structure breakdown
The essay opens with a thesis framing the Church's dual role in politics and warfare, then moves through three evidentiary body paragraphs: the Church's external call to arms (Urban II and William of Tyre), its internal unifying function, and the corruption of religious purpose during warfare (Gunther of Paris and Innocent III). A brief conclusion restates the core tension between ideal and reality.
The Church as Political and Spiritual Authority
As Urban II made clear in his Speech at the Council of Clermont in 1095, the Church was meant to be a bulwark against the effects of the devil among men. When men tried to force their way into and to the head of the Church through machinations, political intrigue, and corruption, that bulwark was split apart and the faithful Christians of Europe were turned against one another. Christianity and the Roman Catholic Church played a significant role in shaping political relationships, overseeing warfare, and supporting notions of political authority in the High Middle Ages. Indeed, the Church had done so from the time Europe began to climb its way out of the Dark Ages, with the crowning of Charlemagne as Holy Roman Emperor on Christmas Day in 800 AD.
In Urban's Council address, he stated of the Church that it is "our mother, as it were, at whose bosom we were nourished, by whose doctrine we were instructed and strengthened, by whose counsel we were admonished" (160). By imploring Christian foot soldiers, knights, and "men of all ranks" to defend the Christian people and their holy mother Church from the invading Turks, Urban was demonstrating the extent of the relationship between the Church and the Christians of Europe and the call to arms. Europe was Christendom in the High Middle Ages, and an attack upon Christendom by a "vile race" bent on destroying the Church and its Christians warranted such a call to arms (Urban II 163). As head of the Church, spiritual authority of the realm, and supporter of those emperors and leaders whose aims aligned with the Church's, the Pope could exercise this privilege, as he did throughout the course of the Holy Wars.
Christianity as the Bond of European Unity
Internally, Christianity was the bond of faith that united the various peoples of the various European nations. It was this bond—based on shared teachings, beliefs, practices, religious observances, and a common culture—that allowed them to look to Rome for guidance in both spiritual and political matters. Externally, the threat of attack from the Turkish people, with their foreign religion viewed as an antagonist to the Christian faith, also served to unite the people of Europe and rally Christians together.
William of Tyre represents how this external threat moved certain Christian soldiers to put their services to use for the good of the Church and for the Lord: "In 1118, certain pious and God-fearing nobles of knightly rank, devoted to the Lord, professed the wish to live perpetually in poverty, chastity, and obedience" (86). One sees in William's History how the thread of the Faith could link men of various classes and backgrounds during the High Middle Ages and shape their political relationships, their interest in warfare, and their notions of political authority. If today's media is the modern pulpit responsible for shaping modern culture and people's beliefs on authority, politics, and war, the pulpits of the High Middle Ages were the real thing—the original pulpits wherein the faithful followers of the Church of Rome were taught what to think and how to live.
