Mahatma Gandhi is FATHER OF NATION. The reason for saying this, is that he was the first Indian who had done something for the foreign people(African). He understand the major problem of our country. Though many people fought for the freedom struggle earlier than him, but still he was the first who fought for the country with involuntary methods and perhaps he was oldest of all the freedom fighters of that period. Thus all the people looked upon him as their guide(like a child before taking a step looks for the guidance of his/her, parents/father). Hence he is known as father of nation.
