Congressional system

A Congressional System is a form of government that features a powerful, lawmaking congress as one of its main organs.

A congressional government is different from a parliamentary government as it does not have a Prime Minister. The congress may have a nominal head, but usuaully the powers of Head of State and Head of Government rest with a president who is not a member of the legislative branch. For this reason, the term congressional system is often used interchangably with presidential system.

Nations with congressional governments are the United States, Mexico, and most nations in South America.
