I heard somewhere that biggest empire to this day remains to be the British Empire but it's just no longer done in old traditional way of being an empire. The several and several countries that still have commonwealth and British overseas territorys are still controlled by the British. I can't think of any other nation that is still doing and to this degree? Does the empire live on? http://upload.wikimedia.org/wikipedia/commons/a/a0/Commonwealth_Realms_map.png All pink on the map is Commonwealth or British overseas terriroys to this day!
