What were the reasons for the birth of the Decembrist movement?

First of all, the emergence of the Decembrist movement was influenced by the unresolved major socio-political and economic issues. During their overseas campaigns, many Russian military personnel got acquainted with the European order. After the victory, they expected innovations from the authorities. But the emperor’s transformative fervor has dried up. Then it was decided to personally seek changes. The views of the Decembrists were influenced by the ideas of the European enlighteners, as well as the revolutionary shake-ups sweeping across Europe.
