'While we can’t pin the invention of homework to a certain teacher, we can trace back who was responsible for making homework that way it is to this day: Johann Gottlieb Fichte, a German philosopher known as the founding father of German nationalism.

In 1814, Prussia had a problem stirring nationalism among its citizens. Instead of serving the country after the war, citizens could choose to go back to whatever they were doing without thinking of dedicating their time and sacrifice to the country. There was no sense of pride or nationalism.

And so, Fichte conceived the Volkschule – a mandatory nine-year education similar to primary and lower secondary education provided by the state – and a Realschule – a secondary school available to aristocrats. Those attending the Volkschule were given the homework we know today as a way to demonstrate the state’s power even during personal time.

The system spread across Europe, but not in a totally dominating way. Some countries continued with their own system, which is why countries such as Finland don’t impose homework on their students. However, in 1843, back when the United States still practiced private tutors or informal lessons, Horace Mann reformed public education after travelling to Prussia and saw their education system and adapted it into the American education system. Thus, homework eventually evolved into a global practice.'
