The notable achievement that the Suffragette Movement advocated for in the early 20th century was women's right to vote. Activists dedicated their efforts to achieving suffrage, fostering a broader conversation about gender equality and the role of women in society. The movement utilized various strategies, including protests, public speeches, and civil disobedience, to raise awareness and apply pressure on legislators. In the United States, the culmination of these efforts led to the passage of the 19th Amendment in 1920, granting women the right to vote and representing a significant step towards political equality in a patriarchal society.
