Stalin enhanced his position within the Communist Party by attaching himself to the legacy of Lenin.

On Lenin’s death, Stalin was able to deliver the main oration at his funeral, while Trotsky didn’t even attend.

This was seen as Stalin being committed to continue Lenin’s work while Trotsky was disrespectful of Lenin’s achievements,

While Stalin presented himself as committed to Lenin’s policies, Trotsky completely misjudged the mood and launched attacks on Lenin’s policies.
