First Republics refer to the initial forms of republican government established in various countries after the decline of monarchies. These governments typically emphasize democratic principles, such as popular sovereignty and the rule of law. The term is often associated with the early republican movements in Europe and the Americas during the late 18th and early 19th centuries. Notable examples of First Republics include the French First Republic, established in 1792, and the United States, which adopted its republican framework in 1789. These republics laid the groundwork for modern democratic systems and influenced subsequent political developments worldwide.
