What Gives an Individual Power

What gives an individual power? Other powerful individuals of course. What gave Macbeth power? Lady Macbeth and others giving him praise for his military accomplishments. As for myself, I believe that Macbeth was a great military man, but a absolutely horrible politician. He may have deserved power initially, but he was immoral going about and when he had it, he didn't know how to properly use it.

Still not dead, na-na-na-na-naa.
