The Constitution
The term for a detailed written plan of government is a "constitution." A constitution typically outlines the structure of government, delineates the powers and responsibilities of different branches of government, and establishes the rights and freedoms of the citizens. Constitutions can be either written or unwritten, with written constitutions being more common in modern nation-states.
The first formal plan of government in the US was known as the Articles of Confederation. However, this was replaced by the constitution which governs the government.
