Masked Busho men cross the River Danube before marching through the town of Mohacs during the annual Busho Carnival in southern Hungary, Sunday, March 6, 2011. This end of winter carnival tradition dates back to the 16th century to Hungary's Ottoman occupation when men of the Sokac ethnic group (related to the Croatians) of Mohacs dressed up in sheep fur and wooden masks in a bid to frighten off their Turkish invaders.
