Answer and Explanation:
Parliament, outraged by the Boston Tea Party and other blatant acts of destruction of British property, enacted the Coercive Acts, also known as the Intolerable Acts, in 1774. The Coercive Acts closed Boston to merchant shipping, established formal British military rule in Massachusetts, made British officials immune to criminal prosecution in America, and required colonists to quarter British troops. The colonists subsequently called the first Continental Congress to consider a united American resistance to the British. on July 4, 1776, the Second Continental Congress officially adopted the Declaration of Independence. Five years later, in October 1781, British General Charles Lord Cornwallis surrendered to American and French forces at Yorktown, Virginia, bringing to an end the last major battle of the Revolution.
The correct answer is "hostilities between American Indians and the Colorado militia."
The Wounded Knee Massacre, which occurred in 1890, was a confrontation between Native Americans who belonged to the Minincojou and the Hunkpapa Lakotas and the Colorado Militia, led by Colonel James Forsyth.
As a result of this battle, nearly 300 Native Americans and 25 American soldiers died. In 1990, the US Congress passed a resolution expressing a "deep regret" for the massacre.
Previous American policy had centred around Isolationism. They did not want to get involved in foreign affairs and believed they didn’t need to. With the Truman doctrine, they wanted to contain the spread of communism, so they were prepared to fight wars and become involved on global politics to prevent such from happening.
