Final answer:
The statement that the United States' first Constitution was called the Articles of Confederation is true. They were drafted in 1777, adopted in 1781, and later replaced by the Constitution after the Constitutional Convention met in 1787 to address its weaknesses.
Step-by-step explanation:
Articles of Confederation as America's First Constitution
It is true that the United States' first Constitution was called the Articles of Confederation. These Articles established the first governing document for the nation, providing a structure for a confederation of states. Drafted in 1777 and adopted in 1781, the Articles of Confederation created a government that had little power to enforce laws, lacking a separate executive or judicial branch. The Confederation Congress could not tax or draft troops, and their ability to enforce laws relied mostly on state consent.
The Constitutional Convention was convened in 1787 with the aim of revising the Articles of Confederation due to its weaknesses; however, it resulted in the formation of an entirely new Constitution. This new Constitution significantly strengthened the central government's powers, such as taxing and regulating interstate commerce, compared to the Articles of Confederation.
Therefore, the statement "Our country's first Constitution was called the Articles of Confederation." is true.
