Final answer:
The most powerful position in medieval society after the king was often held by the Clergy. They had significant influence and power, with people often considering their word as divine will. The church acted as a governing institution carrying out functions of the state.
Step-by-step explanation:
In most medieval societies, the position of power after the king was often held by the Clergy. The clergy were religious leaders such as priests, bishops, and archbishops who carried a significant amount of influence and power. They were responsible for the religious and moral guidance of people, and their word was often considered divine will.
The church in these times acted as a governing institution and carried out many functions of the state including education, law enforcement, and collections of tithes (a tax-like system that collected a portion of people's earnings for the church).
The Knights, Merchants, and Peasants, although essential parts of the society, often did not have as much power and influence as the clergy did. Knights carried out military services, merchants bolstered the economy through trade, and peasants were the workhorse of the society involved in agriculture and services.
