Step 1: Understanding the Congress split.
The Indian National Congress split during the 1907 Surat session due to growing differences between the moderate and extremist factions. The split occurred over ideological differences, with the moderates, led by Gopal Krishna Gokhale, advocating for gradual reform and the extremists, led by Bal Gangadhar Tilak, demanding more direct action. This division weakened the unity of the Congress for some time.
