His fight for others

I think what differentiates him is that he fought for others, especially the ones who couldn't fight their own battle. It is all thanks to the position of Mars & Rahu in the sign of Libra. And not only are Mars & Rahu in Libra but also in the house of career (10th house).

Mars & Rahu are perhaps the most aggressive and passionate planets and together with Libra, they make a lethal combination. Because even though Libra is a peaceful sign; it has a strong sense of justice. Injustice or discrimination brought out the warrior in him. He fought to abolish slavery for the large part of his political career.

"Do you know he shares the Mars in Libra placement with Mahatama Gandhi? If you have this placement too then I am sure you are fighting somewhere for the rights of others"
