Stalin's rise to power was a combination of his ability to manipulate situations and the failure of others to prevent him from taking power, especially Leon Trotsky. Trotsky did not take advantage of several opportunities which would have helped him to crush Stalin politically. When he failed to take advantage of these opportunities, Stalin maneuvered himself into a stronger position within the party by allying with Zinoviev and Kamenev. He manipulated them into crushing Trotsky, thus eliminating the strongest opponent in his path to power. Stalin deftly avoided potential political ruin when Lenin formulated his Testament in December 1922. Lenin's Testament described what he thought of the future of the Party and Party leaders, especially Trotsky and Stalin. Lenin warned of a potential split in which Stalin and Trotsky would be the chief factors. When describing Stalin, Lenin felt that he had concentrated "…unlimited authority… in his hands and whether he will always be capable of using that authority with sufficient caution." (Clark 472). The content of Lenin's Testament eventually became more detrimental to Trotsky than Stalin.

Lenin then added a postscript to the Testament on January 4, 1923, characterizing Stalin as a poor choice for Secreta...
