A politician, political leader, or political figure (from Classical Greek πόλις, “polis”) is a person who is involved in influencing public policy and decision making. This includes people who hold decision-making positions in government, and people who seek those positions, whether by means of election, inheritance, coup d’état, appointment, conquest, or other means. Politics is not limited to governance through public office. Political offices may also be held in corporations. In civil uprisings, politicians may be called freedom fighters. In media campaigns, politicians are often referred to as activists.
