Why was it necessary for congress to assume the role of a national government during the war?

During the war, it was necessary for Congress to assume the role of a national government to effectively coordinate military efforts, manage resources, and unify the states in their fight. The Articles of Confederation had created a weak central government, which hindered decision-making and resource allocation. By stepping into a more central role, Congress could raise funds, recruit troops, and establish alliances, which were crucial for sustaining the war effort. This shift helped to foster a sense of national identity and purpose among the states.
