Women suffrage means giving women the right to cast their votes. Right to vote was denied to women in the beginning. It was argued that women would not exercise this right independently and would cast their votes by the dictates of their husband, father or other male relatives.But with political awakening among women and its
demand by them, they got the Right to Vote for the first time in England in 1918, in USA in 1920 and in India in 1950. .
Now, in almost all the democratic countries of the world, women have been given the Right to Vote.
