King Matt the First (Król Maciuś Pierwszy), published in 1923, tells the story of a young boy who inherits a kingdom and attempts to reform it according to rational, child-centered principles. Matt establishes a children's parliament, institutes fair distribution of resources, abolishes various forms of adult tyranny, and tries to make the world match his sense of justice. The reforms initially succeed. But Matt discovers, slowly and then catastrophically, that the efficiency he has imposed has eliminated something he did not know was valuable: the capacity of his subjects to govern themselves, to develop their own solutions to problems no central authority could anticipate. The optimized kingdom is orderly but brittle. When foreign wars and internal betrayal arrive, it shatters, because the capacity for resilience that would have held it together was the very thing displaced by the optimization. Matt ends in exile, reflecting on what his reforms cost.
