In 1706, the colony of Maryland's General Assembly created the Port of Baltimore at Locust Point. It was built for tobacco trading. The Town of Baltimore was founded on July 30, 1729. It was named after Cecilius Calvert, the British Lord Baltimore. Calvert was the first Proprietary Governor of the Province of Maryland. Baltimore grew quickly in the 1700s as a granary (place for storing cereals and grains) for the sugar plantations in the Caribbean.
