Passage: In the early 1680s, King Charles II of England began taking steps to reorganize the colonies of New England.  The charter of the Massachusetts Bay Colony was revoked in 1684 after its leaders refused to act on his demands for reforms in the colony, when Charles sought to streamline the administration of the colonies and bring them more closely under crown control. He died in 1685 but his successor continued the efforts, Roman Catholic James II, culminating in his creation of the Dominion of New England. He appointed former New York governor Sir Edmund Andros as dominion governor in 1686. The dominion was composed of the territories of the Massachusetts Bay Colony, Plymouth Colony, Connecticut Colony, the Province of New Hampshire, and the Colony of Rhode Island and Providence Plantations. In 1688, its jurisdiction was expanded to include New York, East Jersey, and West Jersey.Andros's rule was extremely unpopular in New England. He disregarded local representation, denied the validity of existing land titles in Massachusetts (which had been dependent on the old charter), restricted town meetings, and forced the Church of England into largely Puritan regions.  He also enforced the Navigation Acts which threatened the existence of certain trading practices of New England. The royal troops stationed in Boston were often mistreated by their officers, who were supporters of the governor and often either Anglican or Roman Catholic.

Question: In which location were trading practices threatened?
New England
