Q:

What does the word "colony" means in the context of a British colony in Berlin?

From the International Herald Tribune (emphasis mine): 

King George and Queen Mary were the guests at breakfast to-day [May 23] of Sir Edward Goschen, the British Ambassador to the Prussian Court. Before breakfast their Majesties received a deputation from the British colony in Berlin, which presented a loyal address. The address was read to their Majesties, who listened to it standing, by Mr. J. W. Louth, the dean of the colony, who also had the honor of reading the colony’s loyal address to King Edward in 1909.

The dictionary definition of colony doesn't seem to apply here, there was no British settlement in Berlin in 1913 (or any other time). What would be the exact definition of the word "colony" in context?

A:

I think colony is used to mean "a group of people from the same place or with the same work or interests who live in a particular city or country or who live together" (the third meaning listed in that page). For example, you could talk of "the American colony in Paris"; that would not mean that Paris is governed from American people.
