<a href='http://americanrevolutionblog.blogspot.com/2009/04/tea-parties-18th-century-v-21st-century.html'>American Revolution Blog</a> points out that the Boston Tea Party in 1773 was organized as a protest against a corporate tax exemption (duties on importing tea to the Americas for the East India Company).  They noted that several wealthy colonists, like John Hancock, had interests in local tea merchants.

The Boston Tea Party Historical Society confirms Hancock’s self-interest in the protests against the East India Company.
