The president of Ireland (Irish: Uachtarán na hÉireann) is the head of state of Ireland and the supreme commander of the Irish Defence Forces. The presidency was established by the Constitution of Ireland in 1937. The first president assumed office in 1938, and became recognised internationally as head of state in 1949 after the coming into effect of the Republic of Ireland Act. The president's official residence and principal workplace is Áras an Uachtaráin in Phoenix Park, Dublin.
The presidency is a predominantly ceremonial institution, serving as the representative of the Irish state both at home and abroad. Nevertheless, the office of president is endowed with certain powers which have constitutional importance.
