Explanation:

When the failure of moderate politics became quite apparent by the end of the 19th century, reaction set in from within the congress circles and this new trend is referred to as the ‘Extremists’ trend. The moderates were criticized for being too cautious and their polities were stereotyped as the politics of mendicancy. This extremism developed in three main regions and under the leadership of three important individuals- Bipin Chandra Pal in Bengal, Bal Gangadhar Tilak in Maharastra and Lala Lajpat Rai in Punjab. In other areas, extremism was less powerful if not totally absent.
