Which historical events occurred right before the US constitution was drafted?

Before the US Constitution was drafted in 1787, several significant events occurred, including the American Revolutionary War (1775-1783), which led to the independence of the thirteen colonies from British rule. Following the war, the Articles of Confederation were adopted in 1781 as the first governing document, but they proved ineffective due to the central government's limited powers. Additionally, the Shays' Rebellion in 1786 highlighted the weaknesses of the Articles and the need for a stronger federal government, prompting the Constitutional Convention in Philadelphia.
