I’ve often fancied that behind every revolution lurks a gardener. Sixty years after flower-sellers took part in the storming of the Bastille in 1789, a young Indian man from a gardening caste—Jyotirao Phule, whose surname means ‘flower’—began his own lifelong assault on a social order far older and even more rank-conscious than the French ancien regime. His intent was to uproot the Brahminical order, and with it the caste system, which blocked access to education, jobs and a sense of self-worth for people of his background.
