Acts implemented by the English government between 1650 and 1673.
The Navigation Acts established three rules for colonial trade.
* Trade coming and leaving the colonies must be carried by English or colonial-built ships, and operated by English or colonial crews.
* All goods imported to the colonies must go through ports in England.
* Specific goods could only be exported to England. Tobacco was the first, but the list expanded.

The acts caused New England ship-building to flourish, provided tobacco from Chesapeake with a monopoly in England, and provided English military forces to prevent attacks from outside forces. The acts also limited the development of colonial manufacturing, made farmers in Chesapeake accept low prices for their crops, and caused colonists to pay high costs for English goods.
