Serfs- They were imprisoned in the lands of the feudal lords, through obligations in the form of services and taxes and fees. They made up the great majority of the feudal population. Hardly, a servant was able to escape from his condition of life. They were the ones who worked hard for everyone, to support the other two orders (clergy and nobles), since members of the clergy and nobles paid no taxes. They had the protection of their feudal lords and knights.
nobles - Order made up of feudal lords, the function of the members of this order was to guarantee the protection of society. They concentrated power over land ownership, as well as exercising control over justice (in the case of feudal lords). They lived in castles, with their families, which were true military fortresses.
Clergy merchants - Although the function of this order was to pray, it exercised political, moral and psychological influence in society. By developing religious activities, they could through mass manipulation control the entire society, from the slaves to the highest positions within feudal society.

Monarchs - to landowners, or fiefs, who held equal or greater power than the monarchs, but were often designated only as a title. They had the protection of the knights.

Not infrequently, the craftsman did not devote all of his available time to craft activities while also being involved in working with the land. In fact, the carriers of this type of ability had a limited radius of action.
