Heads of state are the symbolic leader of a country. Some of them, like King Charles III of the United Kingdom, carry out largely ceremonial roles these days. Others, like Saudi Arabian King Salman, are absolute monarchs and involved in governing the country’s day-to-day activities and policies. It also means that the Saudi monarch gets to do whatever he wants without much consequence from others.
In the United States, the president is both the head of state and head of government. The head of government works with legislators and meets with other world leaders to negotiate agreements and navigate conflicts, among other responsibilities.
