Earls were the most powerful lords, advised the king in the witan council, ensured the king's laws were followed, raised men for the king's army, and protected the people in their lands
Thanes represented less than one percent of the population, were noble warriors who defended the king in return for land, and carried out local duties like guarding tax collectors and organizing fortification repairs
Peasants made up over 70% of the population, worked on their lord's land, farmed their own rented land, and could be asked to fight for their lord in wartime
Slaves made up around 10% of the population, worked on their lord's land or in his house as servants, and had every aspect of their life dictated by their master
The earls competed against one another to be the king's favorite and the one that the king relied on the most so that the king would give them the most rewards and honor
