1968 has shaped radical progressive politics perhaps more than any other year. It was a moment when the social movements of women, race and peace, which had been developing throughout the decade, collided with new left thinking and ideas. It was crystalised through mostly student protest on campuses and in cities across the West. As Mark Perryman sets out here, no government fell as a consequence, but space was opened up for a libertarian and non-statist left to flourish. The reverberations of ‘68 continue to ripple through our politics half a century later.
