This Wedding March comes from Mendelssohn's incidental music to A Midsummer Night's Dream. It became customary to play this at marriage ceremonies from about the mid 19th Century, and particularly after the daughter (also called Victoria) of Queen Victoria chose the piece for her own wedding in 1858.
