Here are the main ones:
* The Journey Itself: The pilgrims are on a journey to Canterbury, and the journey itself presents challenges and opportunities for conflict. They face bad weather, delays, and the constant need to negotiate with each other.
* The Contest of Storytelling: The pilgrims agree to tell stories to entertain each other during the journey, and this competition creates a number of smaller conflicts. Characters try to outdo each other with the cleverness, wit, and morality of their tales. This contest, however, is not simply about telling the best story, but also a way for the characters to showcase their social standing, beliefs, and personal values.
* Social and Religious Conflicts: The pilgrims represent a cross-section of medieval English society, and their stories reflect the social and religious tensions of the time. There are conflicts between the clergy and the common people, between men and women, and between different social classes.
* Individual Conflicts: Many of the individual stories within *The Canterbury Tales* feature their own conflicts, such as love triangles, revenge plots, and battles of wits. These conflicts often reflect broader themes of morality, justice, and the nature of human behavior.
It's important to note that Chaucer doesn't present these conflicts in a simplistic way. He often uses humor and satire to highlight the complexities of human nature and the challenges of navigating a diverse and often contradictory society. The lack of a singular major conflict is one of the strengths of *The Canterbury Tales*, as it allows for a more nuanced and realistic exploration of the human condition.
