The Massachusetts Line was the name given to those units within the Continental Army that were assigned to Massachusetts at various times by the Continental Congress during the American Revolutionary War. These, together with similar contingents from the other twelve states, formed the Continental Line. Line regiments were assigned to a particular state, which was then financially responsible for the maintenance (staffing and supplying) of the regiment. The concept of the line was also particularly important in relation to the promotion of commissioned officers. Officers of the Continental Army below the rank of brigadier general were ordinarily ineligible for promotion except in the line of their own state.
