"The Declaration of Independence, which contains the oft-repeated phrase '…that all men are created equal…' was written by Thomas Jefferson, who owned about 200 slaves at the time and never set any of them free, even upon his death. Jefferson's words certainly had no reference to black people, of whom the majority at that time had no place in American society except as property.

For Americans, equality is a word that has been expanded in its definition since the founding of the country. For Jefferson and many of our Founding Fathers, the phrase '…that all men are created equal…' really meant that 'all free, property-owning males are created equal'. "

The definition has only recently been changed.
