Richmond was a Canadian urban community occupying the northern extremity of the peninsular City of Halifax. (Now part of the Halifax Regional Municipality.) It was the epicentre of the Halifax Explosion of 6 December 1917, the worst disaster in Canadian history, in which as many as 2000 people died and thousands more were injured. From the 1770s Richmond was home to Fort Needham, and in 1819 Richmond Grove (lower Duffus Street) was the site of the famous fatal duel between Richard John Uniacke Jr and William Bowie.
