Colonists from the Province of Maryland established the Port of Baltimore in 1706 to support the tobacco trade with Europe, and established the Town of Baltimore in 1729. The first printing press and newspapers were introduced to Baltimore by Nicholas Hasselbach and William Goddard respectively, in the mid-18th century.
