Guilds
Yes. Thats the Short Answer. There are still Guilds that exist in countries like England, Australia, and certain places in Italy, and germany as well if I'm not mistaken, they have change DRAMATICALLY since the middle ages (as I am led to believe), but are still guilds, and were formed in the middle ages as guilds.
They were called guilds.
The medieval craftsmen united in guilds.
They joined the guilds.
In the Late Middle Ages, the church outsourced the production and performance of Mystery and Miracle Plays to the guilds, who developed Morality Plays.
The upper classes of the Middle Ages usually consisted of the royalty and the nobility. In some places, particularly republican city-states, which were called free towns in some places, and communes in others, there was a patrician class that was not regarded as has important as the nobility and operated under different customs. The merchant class also existed in the entire Middle Ages, gaining importance with the passing of time, ultimately expressing themselves through guilds and leagues of guilds.
The conventional answer is that the middle class developed in the High Middle Ages. It should be understood that the middle class had existed all along, but were not especially important until the High Middle Ages, when their power and numbers became socially important. For example, the earliest guilds were made up of middle class people, and while it is known that some of these existed in the 6th century, the actual date of founding is unknown, so they may have been inherited from Roman times. Guilds of stone cutters and glass makers seem to have originated before the Middle Ages began. Also, there were places where the government was always republican, and the nobility were either absent from the system or had relatively insignificant roles; the Republic of Venice was one such place.

Nearly every craft or trade that required any skill had a guild. There were stonemasons' guilds, silk workers' guilds, carpenters' guilds, jewelers' guilds, merchant guilds of all sorts, and many others. There is a link below to an article on medieval guilds.
