London's Notting Hill Carnival (Europe's largest street festival, drawing around two million visitors over two days) is celebrating its 60th anniversary, having first been organised in 1966 in response to a wave of racist attacks against Caribbean communities in Britain. The festival's Jab Jab parade — in which hundreds of participants don devil horns, coat their skin in motor oil and march at dawn — remains a vivid expression of that defiant spirit, drawing on masquerade traditions from Grenada. Organisers and participants say the event continues to serve both as a cultural celebration and a statement against racism.
