Frederick William III Rule (1 ene 1797 año – 1 ene 1840 año)
Descripción:
 After military collapses and neutrality in wars, William sanctioned the reforms  proposed by his statesmen but this only made for a more powerful bureaucracy 
The final compromise after the Vienna Congress he sided with Russia, this  allowed Prussia to acquire the Rhine province, Westphalia, and much of Saxony. In contrast to these territorial gains, the last 25 years of Frederick William reign show a downward trend of Prussia’s fortunes, to which his personal limitations largely contributed.
