What group of people wanted the United States to become an empire so that they would have access to new sources of raw materials and markets for sales?

With the conquest of land in the west, the oppression of the Indians, the forcible appropriation of Texas and other areas of Mexico in 1848, the American policy, influenced by its own sense of mission, the Manifest Destiny, showed imperialist features early on. Before the Civil War, the internal American debate about the admission of slavery had led to considerable delays in the discussion of one's own position on colonies when it expanded to the American continent. This imperialist view was defended by many, but mostly by  conservatives, called "war eagles".

With the victory in the Spanish-American War in 1898, the United States also entered the circle of imperialist world powers. The acquisition of the Philippines and Puerto Rico as well as the occupation of Cuba and the construction of the Panama Canal were also seen in the domestic political debate as the first step towards competing with the European colonial powers.  

After its victory in World War I, the United States received German island groups in the Pacific from the League of Nations as mandate areas. During the Second World War, other Pacific islands came under US rule.

The foreign policy of the USA in South and Central America up to the 1980s, with its interventions and influences, is often cited as an example of neo-imperial power politics.

1) checks and balances- this idea is implemented in the constitution to ensure that no one branch of the federal government gains too much power. for example, the legislative branch(congress) can approve a bill that will then be sent to the executive branch (president). if the president does not like the bill or thinks that it violates the rights of citizens, he/she can veto the bill. vetoing the bill stops the bill from becoming a law. this check on power ensures that congress makes laws that do not violate the rights of citizens.

2) anti-federalists do not want to ratify the constitution unless it includes a bill of rights. the anti-federalists are worried that the constitution gives too much power to the federal government. having a strong central government caused problems when the us was still part of great britain. this is why the anti-federalists are fearful of this type of system.

3) federalists want a new constitution passed because it will fix america's weak political structure. before the us constitution is implemented, the constitution being used is known as the articles of confederation. this constitution has an extremely weak central government, allowing for disunity among the states.

can't do the whole thing, hope this
