The most important work of Tomas Morus is "The Book of Gold and equally useful as a pleasant book about the best system of the state and the hitherto unknown island of Utopia". - 1516r. Morus assumed that monarchs are tyrants, they oppress people with taxes, spoil coins, are wastelands, do not care about the safety of their subjects, conduct wars and violate the law. Wise reforms cannot repair the evil as long as there is private property. Morus also criticized the development of industry and commerce, believing that prosperity should be based on agricultural and craftsmanship, based on the high morale of society. The Utopian island system did not know the private property. The land, houses, and workshops belonged to the state. He also distinguished himself by his six-hour working day.
Free time was to be spent on learning, the result of which was later incorporated into life practice. The communism of the island's inhabitants assumed strict observance of the principles of equality. The inhabitants of Utopia were to dress in the same way, eat together. Morus believed that such a system guaranteed a high moral level of the inhabitants because who knows that he will not run short of anything, this one is greedy, the political system of Utopia is hierarchical, go democratic at the same time. Every year, 30 families elect their officials, those of their bosses, and the prince is at the head of the bosses. The prince has lifelong power, but in case of a tendency to tyranny, he can be removed. There are different religious beliefs on the island, the principle is universal tolerance.
