What classes were there in the West before the Renaissance

Are you referring specifically to the classes in the pre-Renaissance Middle Ages?

If it was the Middle Ages, then the power class could be divided into emperors, kings and princes, and the rest were nothing more than monks and commoners. Of course, the relationship between theocracy and royal power is more complicated, and the class of monks can also be regarded as the ruling class.

The following is copied from someone else, I hope it helps:

The Duke, a title given to a tribal chief, is the ruler of a land, who still has political, economic, legal, and rights, and whose actions often determine the fate of many people, who are only nominally subordinate.

The marquis, most of whom are border governors, are appointed by the state as the governors of the border areas to be responsible for the rule of several counties, most of these people are from local families, and they are semi-independent forces, and they can appoint local **.

The earl, who is the magistrate of the place, such as the head of the county, is appointed by the king and becomes semi-independent over time. The appointees of dukes, also known as counts, have great powers, especially when representing dukes, and are often ruled by the defenders of social order, such as the Counts of Anjou, who founded the Anjou dynasty in England, and the Counts of Champagne in France.

The above three types of nobility were high nobles, and each had a large amount of territory and could rule independently or semi-independently.

The viscount, who was originally an attendant or assistant to a high-ranking nobleman, led him to deal with affairs and judicial matters. The high nobility was able to exercise their rights independently in their absence, and later began to build castles to form small ruling centers.

Barons, most of whom are connected to the army, receive land from the king on the condition of military service, and a baron has at least 40 50 knightly titles (a knight's title is the area of land required to support a knight).

Before the term class was created, there was no class in Europe.

The emerging bourgeoisie.

The Renaissance movement of the small and medium-sized landlord class was a way of promoting the ancient Greek and Roman culture of the new bourgeoisie, opposing the outdated teachings preached by the Church, and launching a new cultural movement that promoted the emancipation of people's minds, which reflected the interests of the new bourgeoisie.

The Renaissance was a European intellectual and cultural movement that flourished from the 14th to the 17th centuries.

The clergy, the nobility, the urban plebeians, the peasants.

The era before the Renaissance is known as the Middle Ages.

The Middle Ages (c. 476 AD, 1453 AD) was an era in European history (mainly Western Europe) that lasted from the fall of the Western Roman Empire (476 AD) to the Renaissance and the Age of Discovery (late 13th century to mid-14th century). There is also a theory that the Middle Ages ended with the Renaissance and the Age of Discovery. The term "Middle Ages" was first used by the Italian humanist Biondo in the late 15th century.

Europe during this period did not have a strong regime to rule. The Middle Ages or the early Middle Ages are generally called the "Dark Ages" in Europe and the United States, and it is traditionally considered to be a period of relatively slow development in the history of European civilization. (As for its name, it's also called "medieval ages.")"or"middle times", also known as "dark ages.""）

The Renaissance (Italian: rinascimento, made up of ri-"re-re" and nascere "birth", French: la renaissance) was an intellectual and cultural movement that took place in Europe from the mid-14th century to the early 17th century.

It originated in Florence, Milan and Venice in the late Middle Ages, and later spread to various European countries. The term "Renaissance" can also refer roughly to this period of history, but it is only a generic term for this period, as the changes it has caused are not exactly the same across Europe.
