The primary focus of the feminist movement in the early 20th century was advocating for women's suffrage, or the right to vote. Activists fought tirelessly to achieve legal rights and equal opportunities for women, challenging long-standing social norms. This period saw significant organizing, with movements like the National American Woman Suffrage Association emerging to push for change. Achievements in this era laid the groundwork for modern feminism and continued efforts toward gender equality throughout the 20th century and beyond.
