Did the following violate or follow the declaration of independence? And also, did the help the market economy or not help? Explain.

The Missouri Compromise
The Louisiana Purchase
The Trail of Tears

Your first question probably wants you to refer to these sentences from the Declaration of Independence.

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, . . ."

Unfortunately, the Native Americans weren't citizens and were considered less than human. Therefore, the Trail of Tears violates the Declaration's principles.

What do you think about the other two?
