What did Mahatma Gandhi sacrifice to achieve peace?

The truth is nobody, nobody paid heed to Gandhi, neither Hindus or Muslims. Yes, he was let down by all of us; we deserted him whilst the forsaken Mahatma fought alone for peace. It’s a pity that 66 years since independence we have not learned our lessons yet. It’s a pity that we are allowing his sacrifice to go waste. Father, forgive us.

they died because of a disease during the first spanish colonies.

it refers to race, i am pretty sure this was a popular term in nazi germany or something.
