Before the mid-14th century, life in Europe was built on a complex web of personal obligations. This system, known as feudalism, was the political and military backbone of the era. It wasn't a formal, written constitution but a set of customs that bound society together.

At its heart was the relationship between a lord and a vassal. A powerful lord, like a king or a high-ranking noble, would grant a piece of land, called a fief, to a lesser noble, or vassal. In exchange, the vassal pledged loyalty and military service. This created a pyramid of power. A king granted land to his most powerful dukes, who in turn granted smaller fiefs to counts, who then granted land to knights. Each man owed service to the one above him.

This political structure was supported by an economic system called manorialism. The fiefs granted to lords were typically organized into manors. A manor was the lord's estate, which included his castle or manor house, a village, a church, and the surrounding farmland, pastures, and forests.

Most of the population were peasants or serfs who worked the land. Serfs were not slaves who could be bought and sold, but they were not free either. They were legally tied to the land they worked. They couldn't leave the manor without the lord's permission, and their status was inherited. In exchange for a small plot of land for their own families, they owed the lord labor, a share of their crops, and various fees.

During the Middle Ages, the Catholic Church was the single most powerful institution in Europe. It was a unifying force in a politically fragmented continent. The Church's influence touched every aspect of life, from birth to death.

Local priests oversaw baptisms, marriages, and burials. The church calendar dictated the rhythm of the year with its holy days and festivals. For ordinary people, the Church offered a path to salvation and an explanation for the hardships of daily existence. It provided a sense of community and moral guidance.

But the Church's power was also secular. It was a massive landowner, controlling vast territories and collecting tithes, a tax of ten percent on people's earnings. Popes and bishops held significant political sway, sometimes clashing with kings and emperors over authority. Monasteries were the centers of learning, preserving ancient texts and educating the elite.

While medieval society was overwhelmingly rural and agricultural, towns and cities were slowly growing in importance. This growth was fueled by a revival of trade. Merchants traveled dangerous roads and sea lanes to bring goods like silk and spices from the East, and wool, wine, and timber from across Europe.

This created new centers of wealth and opportunity outside the feudal system. A new class of people emerged: merchants, artisans, and bankers who didn't fit neatly into the lord-vassal-serf structure.

Life in these growing towns was organized around guilds. A guild was an association of craftsmen or merchants who controlled the practice of their craft in a particular town. There were guilds for weavers, bakers, blacksmiths, and nearly every other skilled trade.

Guilds set standards for quality, controlled prices, and limited competition. They also provided a social safety net for their members, helping families in times of sickness or death. To become a master craftsman, a young boy would start as an apprentice, then become a journeyman, and finally, if he was skilled enough (and the guild approved), he could open his own shop.

This was the world of medieval Europe: a society bound by personal loyalties, anchored by faith, and powered by the labor of the vast majority who worked the land. It was a rigid and hierarchical world, but one with its own complex systems of governance, economy, and social support. This established order was about to face a challenge that would shake its very foundations.
