Dorchester is a part of Boston located in Suffolk County, Massachusetts. It is now a large and diverse working class community of Boston, and is still a center of Irish-American immigration more or less.

In the summer of 1614, Captain John Smith of Virginia fame, entered Boston Harbor and landed a boat with eight men on the Dorchester shore. The city was founded in 1630.

The first chocolate factory opened in Dorchester, in 1765. Dorchester was also the site of the Battle of Dorchester Heights in 1776, which eventually resulted in the British evacuating Boston.
