The first farm animals also included sheep and cattle. These originated in Mesopotamia between 10,000 and 13,000 years ago. Water buffalo and yak were domesticated shortly after in China, India and Tibet.
In October 1651, the English Parliament passed its Navigation Acts of 1651. This acts were designed to tighten up the government's control over trade between England, its colonies and the rest of the world. The mercantilist theory behind the Navigation Acts assumed that world
trade was fixed and the colonies existed for the parent country.
Main features:
1. Only British ships could transport imported and exported goods from the colonies. The only people who were allowed to trade with the colonies had to be British citizens.
2. Commodities such as sugar, tobacco, and cotton wool which
were produced in the colonies could be exported only to British ports.
