Explain the concept : Left-extremism

Answer: Left-extremism (Naxalism) is a movement that uses violence to bring about change in society and the economy.

It began in 1967 in Naxalbari in West Bengal, as a movement of landless peasants and tribals against landlords and exploitation. Left-extremists do not believe in democracy and use armed struggle against the government. It is active in the forest areas of several states (including Gadchiroli in Maharashtra) and is a serious challenge to Indian democracy. The government tries to tackle it through development schemes and police action.
