In years that followed, the movement's guerrillas, Jangalis, fought against foreign invaders. While they were described as "small landowners in Gilan" that advocated armed insurgency, they were strong enough to resist the advances of the Russian Empire, leading the British to become the major military presence in the region instead. After the Russian Revolution in 1917, Marxists within Iran became more organized and began collaborating with the Jangal movement, with many of these new revolutionaries directly influenced by the Bolsheviks. Later, these Marxists would end up forming the communist Tudeh Party. Even so, there were undoubtedly differences since Mirza supported land reforms but not land redistribution.
