[...] under the absolute monarchy of Frederick William III [...] there were stringent laws obliging parents to send their children to the schools. Children must attend the schools between the ages of seven and fourteen, and no excuses were permitted except physical inability or absolute idiocy. Parents of truants were warned, and finally punished by fines, or by civil disabilities, and as a last resort, the child was taken from its parents and educated and reared by the local authorities.
