1848 After the failure of the European Revolution, German education also stagnated or even regressed. The Ministry of Education was changed to the Ministry of Intellectual Education and Medical Affairs, and several ministers of education distrusted teachers and hated "holistic education". 1849, Frederick William IV angrily accused teachers of taking full responsibility for the revolutionary movement of 1848 Prussian Teacher Training Institute. The government believes that ordinary people can't know everything, and it is necessary to lower the knowledge level of teachers and the standards of primary schools. 1854, the Prussian government issued a decree on normal schools and ethnic schools, stipulating that all primary schools should be managed by the church, with religion as the main teaching content and other subjects reduced to a minimum. In middle schools, the education of basic religious knowledge is emphasized, and students are guided to concentrate on only one subject, preferably a classical subject. Natural subjects are cancelled in the teaching plan of liberal arts middle schools, and Latin and theology are added in practical middle schools. The university dissolved the student union, dismissed professors with liberal ideas, and strictly managed the university. After 1848, nationalism, chauvinism and Prussian national absolutism filled the whole field of education in Germany, which greatly hindered the development of German education.
