define the role of President in our country
Answers
President, in government, the officer in whom the chief executive power of a nation is vested. The president of a republic is the head of state, but the actual power of the president varies from country to country; in the United States, Africa, and Latin America the presidential office is charged with great powers and responsibilities, but the office is relatively weak and largely ceremonial in Europe and in many countries where the prime minister, or premier, functions as the chief executive officer.
In North America the title of president was first used for the chief magistrate of some of the British colonies. These colonial presidents were always associated with a colonial council to which they were elected, and the title of president carried over to the heads of some of the state governments (e.g., Delaware and Pennsylvania) that were organized after the start of the American Revolution in 1776. The title “President of the United States” was originally applied to the officer who presided over sessions of the Continental Congress and of the Congress established under the Articles of Confederation (1781–89). In 1787–88 the framers of the new country’s Constitution created the vastly more powerful office of the presidency of the United States. The president was vested with a variety of duties and powers, including negotiating treaties with foreign governments, signing into law or vetoing legislation passed by Congress, appointing high-ranking members of the executive and all judges of the federal judiciary, and serving as commander in chief of the armed forces.
