Final answer:
Congress enhanced equal rights for marginalized groups by enacting laws such as the Nineteenth Amendment, the Civil Rights Act of 1964, and the Education Amendments Act of 1972. These laws addressed voting rights, school integration, employment and housing discrimination, and sex discrimination in education. They also took steps to accommodate individuals with disabilities and furthered LGBTQ rights.
Step-by-step explanation:
How Congress Contributed to the Extension of Equal Rights
Congress played a significant role in advancing equal rights for marginalized groups throughout the 20th century by enacting various laws and amendments. Key legislative actions included the Nineteenth Amendment in 1920, which granted women the right to vote. In the 1960s, Congress passed civil rights legislation that integrated schools, prohibited discrimination in employment and housing, and expanded access to higher education.
Notably, the Civil Rights Act of 1964 outlawed discrimination based on race, color, religion, sex, or national origin. Importantly, the inclusion of 'sex' in the Act, initially perceived as a stalling tactic by a segregationist, ultimately helped pave the way for the prohibition of gender discrimination in employment. Additionally, Title IX of the Education Amendments Act of 1972, co-authored by Patsy Mink, further prohibited sex discrimination in education.
Moreover, the federal government enacted laws to protect the rights of individuals with disabilities, creating the principle of reasonable accommodation in workplaces and educational institutions. Furthermore, advancements in LGBTQ rights in recent decades have led to the decriminalization of same-sex consensual acts and the legalization of same-sex marriage across the United States.
