Answer 1

Overall how did the United States change from the Election of 1800 through Thomas jefferson’s first term of President. (answer in five sentences or more) plzzzz

Answers

The election of 1800 was fiercely contested and facilitated the rise of the two-party system and bitter partisanship.

Upon entering office, Jefferson focused on reducing the national debt he had inherited from his predecessors. His administration lowered excise taxes while slashing government spending. Additionally, the Jefferson administration reduced the size of the Navy, ultimately bringing the national debt down from $83 to $57 million. Foreign developments, however, including the intensification of piracy along the Barbary Coast, would necessitate the rebuilding of the Navy and its establishment as a permanent part of the US government.

Jefferson dealt with two major challenges to US authority: piracy along the Barbary Coast of North Africa, and British impressment, which resulted in Jefferson instating a mass embargo of European goods, the Embargo Act of 1807.

Jefferson authorized the Louisiana Purchase, which effectively doubled the territory of the United States.

the central factor in Truman's decision to use the atomic bomb was United States rivalry with the Soviet Union not ending the war with Japan Identify two sources listed below that could be used to support the thesis ​

Answers

Answer:

The nuclear bombings carried out by the United States on Hiroshima and Nagasaki in 1945 served to put an end to World War II avoiding an invasion of Japanese territory, thus avoiding a large number of victims on the allied side.

But also, this bombardment demonstrated to the Soviet Union the military power that the United States possessed, as the first tensions that would later unleash the Cold War between both powers were already beginning to emerge. Thus, the nuclear bombardment put a limit to the conflictive will of the Soviets, who began to fear that, in the event of a possible subsequent war against America, it would use this type of bombs against them.

migration from other British colonies, particularly India. The first
shipload of indentured laborers arrived in 1879. Over the next forty
years, 60,000 Indians made landfall in Fiji to work off a girmit, or
