Following the conquest of Kashmir in 1819, a yearly tribute was paid partly in shawls woven from the finest goats fleece and Lahore became a major centre for the shawl trade. Indeed, the Napoleonic generals who helped the Maharajah train his army in modern warfare acted as agents for the export of shawls to Europe. The development in their design, from the simple floral motifs of the Mughal court to overblown, European-influenced patterns is documented in the show.
