Trotsky made a huge mistake at the start of the leadership battle when he was given the wrong date for Lenin’s funeral. He blindly accepted the information without checking for himself. As a result, Trotsky missed the funeral and Stalin took the initiative by giving a speech which put him in the perfect position to be seen as Lenin’s natural successor and disciple.
The unity amongst Stalin’s opponents was all but non-existent. The supposed “united opposition” from the left wing of Trotsky, Kamenev and Zinoviev were in no way united. Kamenev and Zinoviev were often together but they were against Trotsky. In 1924they mounted a campaign against Trotsky by trying to tarnish his reputation. They claimed that Trotsky opposed Lenin in the build up to the October Revolution. Were this to be true Trotsky would be all but finished. This division amongst Stalin’s competitors allowed him to just sit back and allow them all to decimate each other.
Then in 1927 after the left wing were united once more they were thrown out of the party by Stalin for going against party policy, called “factionalism”. This was a fatal mistake by them, particularly Trotsky who passed the “factionalism” law that allowed expulsions.
These mistakes by Stalin’s rivals definitely aided his rise to power; however, it would be somewhat unfair to say that Stalin’s rise to power can be attributed only to the short comings of his opponents. Whilst his rivals were making mistakes Stalin also utilised his know-how to stay out of trouble and manipulate the situation is his favour.
Firstly, as mentioned earlier, Trotsky didn’t attend Lenin’s funeral and this may have partly been Trotsky’s fault but it was Stalin’s cunning that made it possible and his quick thinking saw him deliver a speech at the funeral that would be a factor in his rise to power.
Stalin also knew that he was in a very strong position within the party. He had control over party membership and he used this to his advantage. He got rid of anyone who may support Trotsky and, as noted earlier, he would eventually oust Trotsky himself. He was also in a position knowing that pretty much anyone who he brought into the party would vote for him. It would be a kind of a ‘favour for a favour’ deal since Stalin had granted them membership into the party they would, in turn, vote for him to become the next leader.
As mentioned earlier Stalin was smart enough to steer clear of the left wing battle. He may have been lucky that the battle took place but he used it to the best of his abilities and took advantage.
Stalin was also very smart and astute since, as he allowed the left to battle each other, he initially joined Bukharin to form a coalition on the right wing of the party. Stalin eventually deserted Bukharin and shifted to the left knowing that his ‘employees’, the people he had granted membership into the party, would vote his way regardless of which side of the party he represented. Whether it be forming partnerships or watching as others destroyed each with the squabbles, Stalin cleverly took advantage of people and the coalition they had, or were willing to form..
After looking at all the evidence I would disagree with the statement that it was only his opponents’ mistakes that allowed Stalin to become leader of the Bolshevik party. Stalin was also clever and out-smarted his opponents at nearly every turn. He opponents certainly made mistakes along the way but Stalin was smart enough to capitalise on them, such as the left wing falling foul to factionalism. If he had not been clever and manipulative he wouldn’t have been able to take advantage of the situations that arose. Furthermore, unlike the other contenders, Stalin fully utilised his position within the party to his advantage, such as getting new members that would most likely vote his way.
