A president is the head of the state or the chief executive of a country though the term may also be used to refer to the chief officer of a branch of government or other organizations. Presidents are typically elected by popular vote in a modern republic or a democracy though they may also be chosen by the legislature or by a special electoral college. The president, being the symbolic leader of a nation is considered the representative of the country they preside upon. The United States of America was the first country in modern times to use the term “President” to denote the head of state of a republic when the United States Constitution of 1787 created the office of President of the United States. In the U.S.A, the president is entrusted with two roles. He is the chief executive of the federal government and Commander in Chief of the armed forces. The role of the president is largely ceremonial in parliamentary republics like India, Ireland, Turkey, Germany and Greece.
