A politician is a person who actively participates in governance, policymaking, or public administration, typically by holding or seeking elected office in a government body, such as a president, prime minister, senator, or local councilor. They represent the interests of their constituents, craft or influence legislation, and engage in political activities to shape public policy and societal direction. Politicians often belong to political parties, aligning with specific ideologies, and their roles involve debating issues, negotiating compromises, and addressing public concerns through campaigns, speeches, or lawmaking. Their influence varies by system—democratic, authoritarian, or otherwise—but their primary function is to navigate power structures to enact change or maintain stability, often balancing personal ambition, party loyalty, and public welfare.
