How did the constitution fix the problems of the articles of confederation? use two of the following principles in a paragraph response: rule of law, checks and balances, separation of powers, republicanism, democracy, or federalism.

Federalists felt that the Articles lacked the necessary provisions for a sufficiently effective government. Fundamentally, a federation was sought to replace the confederation. The key criticism by those who favored a more powerful central state was that the government lacked taxing authority; it had to request funds from the states. Also various federalist factions wanted a government that could impose uniform tariffs, give land grants, and assume responsibility for unpaid state war debts. Another criticism of the Articles was that they did not strike the right balance between large and small states in the legislative decision making process. Due to its one-state, one-vote plank, the larger states were expected to contribute more but had only one vote. In May 1786, Charles Pinckney of South Carolina proposed that Congress revise the Articles of Confederation. Recommended changes included granting Congress power over foreign and domestic commerce, and providing means for Congress to collect money from state treasuries. Unanimous approval was necessary to make the alterations, however, and Congress failed to reach a consensus. The weakness of the Articles in establishing an effective unifying government was underscored by the threat of internal conflict both within and between the states, especially after Shays' Rebellion threatened to topple the state government of Massachusetts.
