Lenin wanted Trotsky to succeed him, because he felt that Stalin was too power hungry and crude. Lenin even wrote that before he died, but Stalin found out about it and suppressed it. Stalin as Secretary General of the Communist Party had placed many people loyal to him in high party office and had allied himself with Grigory Zinoviev and Lev Kamenev (both of whom hated Trotsky). Trotsky found himself isolated and without support to succeed Lenin. Stalin, Zinoviev and Kamenev ruled after Lenin died, but Stalin gradually eliminated them too and took complete control in 1928.
