Interpretations of the concept that "all men are created equal" have changed since the declaration of independence was written. which historical development best illustrates this change?

"All Men are Created Equal" has changed since the Declaration of Independence  
Think back to when slavery was still happening. Slavery was inhumane, and should have never happened. Slavery showed that NOT all men were created equal, just because of their and skin color. The Civil War was a historical event that showed that people wanted to fight for slavery to end, and eventually, thanks to the South, it did. So, "All Men are Created Equally" has changed because now people actually think that it is true. Racism is starting to go down.
