Education in Germany
Public universities in Germany are funded by the federal states and do not charge tuition fees. However, all enrolled students do have to pay a semester fee ("Semesterbeitrag"). This fee consists of an administrative fee for the university (only in some of the states), a fee for "Studentenwerk", which is a statutory student affairs organization, a fee for the university's AStA ("Allgemeiner Studentenausschuss", students' government) and "Studentenschaft" (students' union), at many universities a fee for public transportation, and possibly more fees as decided by the university's students' parliament (e.g., for a cooperation with a local theater granting free entry for students). Summed up, the semester fee usually ranges between €150 and €350.
History of European research universities
The situation in Germany, or rather the various German states, was different. The specific German Bildungsbürgertum, which emerged in starting from the mid-18th century with an educational ideal based on idealistic values and classical antiquity had failed in gaining political power and in its aims for nationalist movement. The Bildungsbürger turned to education as means to construct a common national culture and strived for freedom against the nobility in power. Only when Prussia and its absolutist government had been utterly defeated by the Napoleonic armies in 1806, the weakness of the defeated government allowed for the Prussian reforms of the county's institutions. 
"Just as primary instruction makes the teacher possible, so he renders himself dispensable through schooling at the secondary level. The university teacher is thus no longer a teacher and the student is no longer a pupil. Instead the student conducts research on his own behalf and the professor supervises his research and supports him in it." Early 19th-century American educators were also fascinated by German educational trends. The Prussian approach was used for example in the Michigan Constitution of 1835, which fully embraced the overall Prussian system by introducing a range of primary schools, secondary schools, and the University of Michigan itself, all administered by the state and supported with tax-based funding. However, some of the concepts in the Prussian reforms of primordial education, "Bildung" and its close interaction of education, society and nation-building are in conflict with American state-sceptical libertarian thinking.
Freedom was an important concept in the German university model, and the system of professors was based on competition and freedom: although professors served as state functionaries, they had the freedom to choose between several states, and their identity and prestige arose from the specialization of scientific disciplines.
