Keeping pace with the international student movement, the 1960s were ‘street fighting years’ in West Bengal too. The Vietnam War, Che Guevara’s death in Bolivia, the Cultural Revolution in China etc. captured students’ imagination, encouraging them to protest in strength against growing social inequality. Their more urgent call was to rally around international issues—Vietnam and US imperialism dominated. In December 1968, Robert McNamara, then World Bank chairman and former US defence secretary (1961-68), visited Calcutta to consider a loan proposal for a big urban development project. Students came out in force; violent clashes broke out with the police, bringing the city to a halt. McNamara could only tour the city surreptitiously at night. Earlier, in 1966, thousands of students took active part in the food movement; some died in police firing. That year, students of Presidency College started a movement to stop authorities from expelling six students, including Ashim Chatterjee (later a top CPI-ML leader), for political activities. The movement took a radical turn to merge with the brewing Naxalite movement.
