How you manage to achieve it is up to you.

•Expand your territory by military occupation to gain more power, but do not spread too thin too fast or your empire will crumble even faster.
•Analyze and manipulate diplomatic relations to invade countries while avoiding creating too many powerful enemies.
•Use your country's resources to sustain your research and military campaigns, but if you spend too much your land will be impoverished and you will fall behind your rivals in the balance of power.
•Determine your country's economic policy and reach a high economic growth, which might allow you to outpace your rivals in the power race even without using military force.
