The first attack on fools' entertainment is religious forces. During the Reformation, many religious thoughts were against recreational activities, such as Calvinism and Puritanism in Britain. They think this kind of entertainment is immoral and that it is this kind of entertainment that leads to the corruption of Catholicism. Like someone? Pope Geneva? Calvin, a religious reformer, under his rule, singing, drinking and playing the piano are immoral, not to mention fooling around on April Fool's Day.

Interestingly, in the Catholic circle, the entertainment activities of fools are also discriminated against, which is a bit complicated. Because during the Reformation, various religious reformers criticized the corruption of Catholicism, saying that Catholicism was influenced by pagan traditions. Therefore, in 1562, the Catholic church held a conference on the reorganization of doctrines to discuss this issue, which was the famous 22nd talent conference. The conclusion of the discussion is that Catholicism should be rectified and religious reformers should not be given an opportunity. Pastors, in particular, should set an example and put an end to all immoral forms of entertainment.

In other words, just to show that you are better than Protestantism? Devotion? More? Orthodox? The Catholic Church began to purify itself. Since then, the whole Catholic world has also begun to oppose the entertainment activities of fools, and April Fool's Day elections, jokes and pranks have all been banned.

In the Enlightenment, one of the themes of the Enlightenment was to criticize the medieval church and superstition, but this did not bring about the revival of fools' entertainment activities. On the contrary, what is a theme of the Enlightenment? Rational? People are required to be self-disciplined and guide their lives with sound rationality. In this way, the fool's banter, satire, prank entertainment, in the Enlightenment and later times, it is very vulgar and obscene. As a result, the entertainment of fools originated from the middle ages actually declined under the simultaneous opposition of the religious reform forces, the Catholic conservative forces and the enlightenment forces.

However, the activities of fools have not disappeared. In fact, the rejection of April Fool's Day by churches, religious reformers and enlighteners is actually the differentiation of entertainment methods between the whole elite and civilians. Due to the constant stigma of April Fool's Day, aristocratic elites and intellectuals gradually feel that this kind of fool's prank is an entertainment activity that the lower class can't get on the table. As gentlemen and decent people, they should pursue a nobler and more civilized way of life, instead of mixing with the people. In the Middle Ages, the carnival for fools, which was attended by civilians, nobles and monks, gradually disappeared.
