All the monarchs of Europe had court jesters. They had to amuse the king and his guests. It was believed that the jester was an idiot who was allowed to do much of what was not allowed even to the king himself. In fact, the jester was the alter ego of the master. In a simple humorous and often allegorical form, he expressed the will of the lord. He also influenced the policy of monarchs. In Europe, the tradition of hiring jesters ended with the advent of the era of the Enlightenment and the Reformation.
We remember the kings and emperors, but undeservedly forget those who were not afraid of a sharp word, even if pretending to be a fool, to direct the rulers to the right path. Even the wise Khodja Nasreddin, as they say, was a jester of Tamerlane himself. Some of the court jesters were smarter than the kings themselves.
