After Lenin’s death in 1924 the Bolsheviks (although not out rightly stated) were in need of a new leader. The power struggle occurred from 1923-1929 and eventually Stalin effectively became the leader of the USSR due to many reasons, including the weaknesses of Trotsky.
Trotsky had not been a Bolshevik initially – he converted from the Menshevik party in 1917. Therefore some of the party members doubted him as 100% trustworthy.

He had regarded him as inferior, which may have been true if looking at intelligence, however Trotsky’s arrogance blinded him as his disregard for anyone less intelligent than himself again lost him support, whilst Stalin was gaining it throughout the judgements he put forward and the allies he was creating.
