Germany has been one of the biggest powers in the world since the 20th century. Although it has experienced the baptism of two world wars in succession, it has now become the leader of the European continent and plays an important role on the world stage. As we all know, Germany was severely divided more than 100 years ago. However, in 187 1 year, the kingdom of Prussia finally merged with Germany, and Germany is no longer just a geographical term. So why did Prussia unite with Germany instead of other countries? The powerful Austro-Hungarian Empire is different. Due to educational factors, the Kingdom of Prussia has established a comprehensive and effective education system. First of all, Prussia divided education into three levels: primary, intermediate and advanced. Primary school lasts for four years, middle school lasts for six years, and higher education is a university. Entering junior high school and senior high school must pass the entrance examination, thus breaking the old rule based on disciples' right to education.

In addition, Prussia strictly stipulates that only trained qualified teachers can teach, which greatly improves the level of teachers. Prussia has also established many new universities, focusing on cultivating high-quality talents. The University of Berlin was founded in 1809. The school implements the principles of academic freedom, the combination of teaching and science, and the leading position in scientific research, recruiting talents and attracting many academic celebrities to teach. Later, these Prussian universities, represented by Berlin University, finally made indelible scientific contributions to the outbreak of the second industrial revolution in Germany and objectively accelerated the process of Prussia's unification of Germany.

The French call Prussia a country with barracks and schools, and its excellent education system is obvious to all. Science and technology are the primary productive forces, and education is the only way to promote science and technology. The perfect education system has greatly improved Prussia's soft power and laid a solid foundation for the future reunification of Germany. Economically speaking, Prussia led the German states to establish a unified economic system, which laid the economic foundation for the establishment of the German Empire in the future. There are two things worth noting. One is to abolish serfdom, and the other is to establish a customs union. Abolish serfdom, although the reform of serfdom in Prussia was incomplete and top-down.
