When Did The Black Death Start

The Black Death started in 1348-1349 in England. It seems to have travelled across the south in bubonic form during the summer months of 1348; it hit London in September 1348, and spread into East Anglia all along the coast early during the new year. By spring 1349, it was ravaging Wales and the Midlands, and by late summer, it had made the leap across the Irish Sea and had penetrated the north.  Whether they caught the plague by this action, or whether it found its way north via other means, it was taking its revenge on Scotland by 1350. The Black Death also arrived in Europe by sea in October 1347 when 12 Genoese trading ships docked at the Sicilian port of Messina after a long journey through the Black Sea.
