One major difference between Stanton's Declaration of Sentiments and the Declaration of Independence was the rights granted to women.
In the Declaration of Independence, it says that "all men are created equal." In the Declaration of Sentiments, it discusses how all men and women are equal. The Declaration of Sentiments then goes on to discuss all the different abilities that women did not have at this time. This includes the ability to: vote, keep their wages, and own property. All of these grievances (aka sentiments) were the core of the women's suffrage movement of the late 19th and early 20th century.
