The British Empire
The British Empire by far stretched across 33.7 million square miles and was the largest empire in terms of population to ever exist. Interestingly, the British Empire had once recorded an estimated 35.9% GDP, which works out to about 1,111 billion in 1870. This is a great figure, indeed.
This empire is still in existence as it covers a lot to include some Caribbean Islands, Australia, and New Zealand. Long live the queen, perhaps?
