The ideas from the Declaration of Independence that support women’s suffrage are primarily found in the phrase “deriving their just Powers from the Consent of the Governed.”
This principle emphasizes that governments derive their authority from the consent of the people, which implies that all individuals, regardless of gender, should have a voice in granting that consent through voting. Therefore, this idea aligns strongly with the arguments for women's suffrage, advocating for the inclusion of women in the democratic process.
While other phrases such as “Life, Liberty and the Pursuit of Happiness” also resonate with the goals of the women's suffrage movement, the strongest support comes from the idea of consent.
