Frederick the Great made school compulsory in 1763, for children aged five to thirteen.
In 1763, Frederick the Great of Prussia issued the Generallandschulreglement, a decree authored by Johann Julius Hecker that required all children between the ages of five and thirteen to attend school.1 Prussia was among the first states in the world to introduce tax-funded, compulsory primary education. France and Great Britain would not achieve the same until the 1880s.
The system provided an eight-year course of primary education called Volksschule, covering reading, writing, religious instruction, and a strict education in duty, discipline, and obedience. Frederick also formalized secondary stages: the Realschule and the Gymnasium, which prepared students for university.2
After Prussia's catastrophic defeat by Napoleon at the Battles of Jena and Auerstedt in 1806, reformers overhauled the system. In 1809, Wilhelm von Humboldt was appointed minister of education. His reforms emphasized broad general knowledge over vocational training and insisted on academic freedom, though the system remained centrally administered. In 1810, Prussia introduced state certification requirements for teachers, significantly raising the standard of instruction across the country.3
By the 1830s, the system had achieved compulsory attendance, a prescribed national curriculum for each grade, trained and certified teachers with state salaries, national examinations, and mandatory kindergarten.4
The Prussian model was adopted internationally. Horace Mann, then secretary of the Massachusetts Board of Education, traveled to Prussia in 1843, studied its school system, and returned to advocate for a similar structure in the United States.5 In 1852, Massachusetts became the first U.S. state to pass a compulsory education law. Other states followed over the next several decades.
Critics have argued that the system was designed to produce obedient citizens and competent workers, not independent thinkers. Johann Gottlieb Fichte, a philosopher who influenced the Prussian reforms, wrote that schools must fashion students in such a way that they cannot will otherwise than what the state wishes them to will.6 Supporters counter that the system reduced illiteracy, professionalized teaching, and created the infrastructure on which all modern public education was built. Both claims have evidence behind them.
