How did feminism end?

First wave feminism ended around 1920, because the Nineteenth Amendment was ratified, giving women the vote. First wave feminism had largely focused on getting the vote. Carrie Chapman Catt, one of the leaders of the Suffrage Movement (within first wave feminism), had in fact desired to make the suffrage movement so central to the first wave feminist movement, that she had bribed newspapers and used contacts in the press to get articles about other aspects of the women's movement removed, so that suffrage was the only issue focused on, in order to make it stronger. After suffrage was achieved, no other movements within first wave feminism really had any momentum, support, visibility, or resources, since so much had been thrown behind the Suffrage Movement, so first wave feminism ended, adn gave way to second wave feminism in the 1960s.
