When did the Indian National Congress split?

The Indian National Congress split in 1907 permanently due to a rift in the extremists and the moderate factions. They had earlier patched their differences but had split for good in 1907.

The moderates wanted to resort to non-violent means to achieve their goals for Indian independence while the extremists wanted to use radical methods to achieve complete independence from Britain.
