The study of power as it relates to Global History and Geography is the study of how cultures, ideologies, social movements, and religions often affect others beyond their immediate sphere of influence.  The Roman Empire at its height controlled most of the Mediterranean world, extending its influence far beyond its borders.  Islam, which started in modern day Saudi Arabia, quickly spread its influence beyond to control much of the same area the Romans had centuries before.  In the twentieth century, the ideology of fascism quickly spread out of Italy and Germany to influence most of mainland Europe, mainly through military force.

The study of power is often the study of one culture's ideas and values supplanting another's, often through force.  During the Age of Exploration, European countries extended their political, social, and economic power to take over, and in many cases destroy, native cultures around the globe.  This occurred again in the 19th century, when European countries sought to control others for economic gain.

The study of power is often a look at the darker side of human history.  Yet, the power of the world's major religions has often been a positive influence on cultures as they provide codes of conduct and morality to work toward in times of strife.  The power of Christianity in Europe during the Middle Ages helped to keep society running during those dark times.
