Trotsky continues to dig his grave by launching attacks on the party bureaucracy.  His criticism was none too popular with the party members and he was isolated by Stalin, who sided with Zinoviev and Kamanev.

One weapon that Stalin was able to use was Lenin’s rule against factionalism, the forming of factions within the party.  He was able to use this whenever disputes over ideology and ideas surfaced.  This limited Trotsky’s ability to organize his supporters.

In 1926, Trotsky joined forces with Zinoviev and Kamanev to form the United Opposition.

They were primarily concerned with NEP, which in their eyes, had to go because of its capitalist elements.

However, opposing them was the Right Opposition, which called for an intensification of NEP.

Trotsky was also concerned with the policy of “Permanent Revolution”.

Permanent Revolution was the need to spread the revolution worldwide, in order to guarantee the success of the Bolshevik Revolution

Stalin opposed this, with “Socialism in One Country”, which essentially says that they must perfect the revolution in Russia before anything else could be done.

The United Opposition was a wary alliance and Stalin was able to exploit their differences and outmaneuver them.

They were not allowed to talk at the Fifteenth Party Conference and from this point forward, they had to work in secret.

Accursed of factionalism, they were expelled from the Politburo.

Trotsky in particular was exiled.
