Final answer:
After the Declaration of Independence was written, women's rights activists and civil rights activists, including African Americans, continued to fight for equal rights and freedoms. Labor rights advocates also fought for fair treatment, although environmental campaigners are not directly related to this historical struggle for human equality.
Step-by-step explanation:
Despite the Declaration of Independence stating that "all men are created equal", several groups continued to fight for their rights after it was written. Among these were A) Women's rights activists who sought greater political and economic rights, B) Civil rights activists who aimed to end slavery and achieve real equality for African Americans, and C) Labor rights advocates who fought for worker protections and fair wages. D) Environmental rights campaigners, while also fighting for rights, were not directly related to the contradictions in the Declaration of Independence concerning human equality.
Following the American Revolution, women found themselves capable of managing businesses and farms during the absence of men, but were denied political rights and economic freedoms post-war. African Americans fought valiantly to end slavery and gain equal status, with many joining causes hoping for freedom. Laws like the Civil Rights Act of 1964, and movements for women's suffrage, particularly in the early 20th century, highlight the ongoing struggle for equality and the gradual realization of rights for marginalized groups.
