National government

National Governments were governing factions which led the nations on Earth for centuries before the dawn of the United Nations Space Command.

Ancient Times
They started out as primitive tribes. Over time they advanced into city states like Sparta, Athens, and Rome. The more successful city states managed to form small countries, nations, then empires. For a long period the greatest empire in western civilization was Rome, whom based their success off of that of the Greeks. After Rome fell to German barbarians in 476 A.D., Europe went though a period of anarchy (also known as the Dark Ages), eventually entering the Middle Ages.

Middle and Modern Times
The dominant power at the time was the Spanish Empire with the discovery of the New World, before being surpassed by the British Empire, which became the largest empire in Earth's history. After the First World War, Britain began to rapidly decline as a superpower and the United States rose to prominence. After World War II the two remaining superpowers, Russia and the United States, plunged themselves into the Cold War with the discovery of nuclear fission and later fusion. In the 1960's the Nuclear Age gave way to the Space Age, with the accomplishments of the superpowers being emulated by Europe, Japan, and eventually the rest of the world. Although the nuclear superpowers signed a treaty to limit their nuclear stockpiles (eventually leading to the the end of the Cold War), third world countries got their hands on nuclear technology which led to terrorism and escalated conflicts between other smaller nations such as Pakistan and India.

United Earth Goverment
The National Governments of Earth engaged in several colonial proxy-wars, one of which was the Interplanetary War in the 2100's. Ultimately, the individual national governments on Earth were subsumed by a centralized Earth government known as the United Earth Government, which controls the United Nations Space Command. However, though the influence of the governments waned, the individual cultures, languages, and other such unique beliefs existed among the people under the UNSC until much later.
