Extremist Movement in India: Context

The Indian nationalist movement saw a split in the early 20th century between the Moderates and the Extremists within the Indian National Congress. While the Moderates favored gradual reform through constitutional means, the Extremists advocated for more assertive methods, including Swaraj (self-rule), Swadeshi (use of domestic goods), and Boycott.

Partition of Bengal: The Immediate Cause

The Partition of Bengal in 1905, orchestrated by the British Viceroy Lord Curzon, is widely regarded as the immediate trigger for the significant rise and prominence of the Extremist faction. The official reason given was administrative convenience, but it was widely perceived by Indians as a 'divide and rule' tactic aimed at weakening the strong nationalist sentiment in the region and fostering Hindu-Muslim division.

This controversial decision sparked widespread outrage and protests across India, particularly in Bengal. The Extremist leaders, such as Bal Gangadhar Tilak, Lala Lajpat Rai, and Bipin Chandra Pal, effectively utilized this public anger. They championed the Swadeshi and Boycott movements, encouraging Indians to reject British goods and institutions and promote domestic production and national education. This strategy mobilized the masses and intensified the demand for self-rule, marking a crucial phase in the growth of the Extremist movement.

Analysis of Other Options

Let's examine why the other options were not the *immediate cause* for the rise of the Extremist movement:

• Jallianwala Bagh massacre (1919): This tragic event occurred much later, in 1919. While it further fueled anti-British sentiment and strengthened nationalist resolve, the Extremist movement had already emerged and gained significant momentum well before this date, following the Partition of Bengal.
• The passing of the Rowlatt Act (1919): Similar to the Jallianwala Bagh massacre, the Rowlatt Act was passed in 1919. It represented a later phase of British repressive policies and triggered widespread protests (like the one at Jallianwala Bagh), but it did not initiate the rise of the Extremist movement itself.
• Arrest of Bal Gangadhar Tilak (1908): Bal Gangadhar Tilak was a key leader of the Extremist faction. His arrest and subsequent imprisonment in 1908 were significant events that caused widespread protests and solidified his image as a martyr among his supporters. However, this arrest happened *after* the Extremist movement had already gained considerable traction, spurred by the 1905 Partition. The Partition was the initial spark that allowed leaders like Tilak to amplify their calls for assertive action.

Therefore, the Partition of Bengal (1905) stands out as the direct and immediate catalyst that propelled the Extremist movement to the forefront of Indian political discourse.
