Rooting out corruption.

Corruption.png Corruption measures a country's bureaucratic morality throughout the ranks. A country with high corruption suffers widely from embezzlement and loss of the leader's authority, while a country with no corruption is free to prosper. Unlike inflation, corruption does not directly affect monetary costs, instead affecting other areas of the state (though it may indirectly affect income due to raising the local autonomy floor of provinces).

Effects[edit]

Every point of corruption gives the following:[1]

Foreign spy detection.png −25% Foreign spy detection
Spy network construction.png −50% Spy network construction
All power costs.png +100% All power costs
Minimum autonomy.png 50% Minimum autonomy
National unrest.png −20 National unrest
Mandate.png −1 Imperial mandate

Eliminating corruption enables beneficial Corruption events, while increasing corruption enables increasingly bad events. Corruption also increases the amount of monarch power which can be stored at the same level as the respective power cost increase.
