The second biggest was by Chairmen Mao in the 1950's
when China became a Communist nation. nearly 30 million according to
china's own information.
And the 3rd biggest genocide was by
Joseph Stalin who killed some 23 million of his own people including 7

"winner". To site European's vs. unnamed native tribes is classic case
of not understanding the question or history.
