The main goal of the women's suffrage movement in the early 20th century was to secure the right to vote for women. Advocates aimed to achieve political equality and combat discrimination, arguing that women deserved a voice in government and society. The movement mobilized support through protests, lobbying, and public campaigns, culminating in significant milestones like the passage of the 19th Amendment in the United States in 1920, granting women the right to vote. This victory represented a critical step toward gender equality and inspired further activism for women's rights and social justice.
