After the revelutinary war what were some challenges faced by the new government under the articals of confederation

1) No independent judiciary

The Articles of Confederation offered no system of courts in the jurisdiction of the national government. This meant that the entire judiciary branch was dependent on the states. According to Article IV, “Full faith and credit shall be given in each of these States to the records, acts, and judicial proceedings of the courts and magistrates of every other State.” 8 Consequently, states could overturn national actions that they found objectionable. Since Congress had no means to enforce its laws, the states could simply ignore national laws without fear of retribution. Also, since there was no national courts system, individual persons or states could not file complaints against the national government. The states could always ignore anything they disagreed with, but if a citizen had a grievance with the national government there was no system in place to hear the lawsuit.

2) No foreign affairs head

One of the glaring differences between the Articles of Confederation and its successor—the Constitution of the United States—was its lack of a chief executive. Most notably, the lack of a presidential figure or body left America without a representative to conduct foreign affairs. Britain actually complained of such difficulties, protesting that they did not know who to contact in order to initiate diplomacy. Without a single executive to act as the head of foreign affairs, America was at a serious diplomatic disadvantage.

3) Inability to deal with internal and external threats

It seems counterintuitive that a body of government would be tasked with declaring war, but not be allowed to commission an armed force. According to the Articles of Confederation, Congress had the sole power to make peace and war, but did not have the authority to raise an army of its own: “The United States in Congress assembled, shall have the sole and exclusive right and power of determining on peace and war.” 9 Instead, the national government had to rely on state militia. Since it was dependent on state troops, Congress was severely limited in its capabilities to quickly and effectively responding to internal and external threats. Abroad, Congress failed to defend American from the continuing threat of Britain following the Revolutionary War. Shortly after signing of the Treaty of Paris in 1783, Britain began to break the agreement.

The answer is "Soldiers brought back new technology and belief systems." :)
