The Big Four
General and unofficial term describing the four societies that rule much of the Milky Way Galaxy.
The term was coined during the first Armistice conference and after the Second Intergalactic war.
The term is especially used by the many smaller and independent societies in Free Space and in regions beyond.
Until 5025 the Big Four were enemies and the outbreak of hostilities was always very likely between any of the Big Four. Only the Second Armistice signed by representatives of the Big Four and all independent nations of Free Space kept war from breaking out.
In 5025 the Nul-Nul joined the United Stars and the term Big Four slowly faded away. It was replaced by the term. “The Big Two” after the combined Union/Nul assault on the Shiss and the utter destruction of the Shiss Hegemony.
