On this day in 1967 between 20,000 and 30,000 people attended the ‘Human Be-In’ in San Francisco’s Golden Gate Park. It was organised to protest California’s ban on LSD, with guest speakers like Timothy Leary and Allen Ginsberg. The event launched the ‘Summer of Love’ in the 1960s, a period which for many defines the culture of 1960s America.
This was an iconic moment in the hippie movement of the 1960s and influenced the movement for years after. It coined the usage of the term ‘-In’ after gatherings,. This was later adopted by the 1968 ‘Yip-In’ and ‘Love-In’ and John Lennon’s 1969 ‘Bed-In’.
