Widespread talk of liberty gave thousands of slaves high expectations, and many were ready to fight for a democratic revolution that might offer them freedom. In 1775 at least 10 to 15 black soldiers, including some slaves, fought against the British at the battles of Lexington and Bunker Hill. Two of these men, Salem Poor and Peter Salem, earned special distinction for their bravery. By 1776, however, it had become clear that the revolutionary rhetoric of the founding fathers did not include enslaved blacks. The Declaration of Independence promised liberty for all men but failed to put an end to slavery; and although they had proved themselves in battle, the Continental Congress adopted a policy of excluding black soldiers from the army. In spite of these discouragements, many free and enslaved African Americans in New England were willing to take up arms against the British. As soon states found it increasingly difficult to fill their enlistment quotas, they began to turn to this untapped pool of manpower. Eventually every state above the Potomac River recruited slaves for military service, usually in exchange for their freedom. By the end of the war from 5,000 to 8,000 blacks had served the American cause in some capacity, either on the battlefield, behind the lines in noncombatant roles, or on the seas.
The cultivation of maize allowed for the development of Tenochtitlan because it created a staple crop that all citizens can grow. Growing crops is an essential part of any society, as it provides food which individuals/families can live off. Without this staple crop, this group of Aztecs would need to have a more nomadic lifestyle in which they constantly moved to hunt animals.
Tenochtitlan was vulnerable to conquest because it was surrounded by water. Being surrounded by water made it easily accesible to other countries. This is why Spain was able to invade and take over Tenochtitlan during the 16th century.
