We had to have the violent and long-running Naxalism movement that disrupted the State forever, the political uncertainty of 1967-72, which saw many aaya ram gaya ram Chief Ministers and the sheer tyranny of Congress Chief Minister SS Ray (that shut the party out of the State forever) before the CPM could come to power.
Mamata Banerjee found herself as the Chief Opposition after the 1996, 2001 and 2006 Assembly elections (hence her stints at the Centre to bide her time) before she could claim the throne in 2011.
The BJP has just now grabbed the mantle of Chief Opposition of West Bengal in 2021.
The other side of the coin: It’s very difficult to lose power in Bengal too…
From 1947-77, 30 years, the Congress was either the Ruler or Chief Disruptor. It was a tragedy of errors that led to their exit.
The CPM ruled from 1977-2011, a record 34 years.
And even now Mamata has got three straight terms and will see herself as a favourite for 2026 too.
