Europe came under the rule of one emperor when Charlemagne was crowned.
The north and south began o use conscription early in the war to ensure that they had enough people in their army fighting in the warfront.
<u>Explanation:</u>
The conscription act passed by the US congress during the civil war demanded that all citizens between the age of 20 and 45 have to join the military to serve in the war. The conscription also mentioned aliens who required the citizenship of US. In order to be exempted from the military service people had to pay $300 which was a high sum at that time.
This meant that only the rich could afford exemption and this led to revolts in many parts of US. The Draft Riots of New York is an example. The confederate states government also passed the conscription draft to enhance the strength of their military force.
The Marshall Plan could be understood as part of an American desire to stop the spread of communism.
After World War II, the US was worried about the growing size/influence of the Soviet Union and their communist system. Their main concern was that this system would spread to European countries and eventually the Soviet Union and their communist ideas would infiltrate the US.
To ensure that this did not happen, the US gave $13 billion worth of economic aid to European countries that were greatly affected by World War II. This included countries like Great Britain and France. This assistance would make sure that these countries did not fall under the control of the Soviet Union.
