Which constitutional amendment expanded the definition of citizenship to include womens right to vote

The 19th Amendment amendment states that 'the right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex'.

Starting in the 1800s, women organized, petitioned, and picketed to win the right to vote, but it took them decades to accomplish their purpose. The 19th Amendment (1920) to the Constitution of the United States provides men and women with equal voting rights. The amendment states that the right of citizens to vote "shall not be denied or abridged by the United States or by any State on account of sex." Although this equality was implied in the 14th Amendment (1868), most of the states continued to restrict or prohibit women's suffrage.
