Earth

"Fight for her."

- Bulletin board poster of Earth

Earth is one of the four terrestrial planets in the Solar system and is the home planet of the Human race, as well as many other various life forms. It is the capital planet of the United Nations, the Unified Earth Government, and the United Nations Space Command. Earth was possibly the most populated planet of the Human space territories. For a significant amount of humanity's history, it was to them the only known place in the universe to support life.

Creation
The Earth first formed about 4.6 billion years ago, and gave rise to the first single-celled organisms about 3.9 billion years ago. About 200,000 years ago, the ancestors of modern humans, Homo Sapiens, evolved in Africa. Indigenous to Eastern Africa, they gradually spread across the entire planet. The enigmatic race known as the Forerunners discovered Earth 100,000 years ago near the end of their war with the Flood, and built a machine to generate a slipspace portal to the Ark in Africa. They also indexed the human species as a part of their "Conservation Measure" to preserve life in the galaxy after the activation of the Halo Array. After the array's activation, human life was planted back on Earth.

Civilization and the Modern Age
Eventually, the humans, originally consisting of groups of hunter-gatherers, began to develop into civilizations. These civilizations gradually became more and more complex, with some becoming nation-states and empires.

By the year 1914, much of the world was divided into two factions, the Triple Entente, or Allies: the United Kingdom, France, Russia, and later the United States of America, and the Triple Alliance, or Central Powers: Germany, Austria-Hungary, and other nations of similar ideals. The Central Powers were defeated at the end of World War I in 1918, resulting in a decade of prosperity for the Allies, followed by an economic depression and the rise of Fascism, Nazism, and Communism in many countries. In 1939, another World War erupted, between the Allies (Britain, the Soviet Union, later the United States, and many other nations) and the Axis (Nazi Germany, Fascist Italy, and the Empire of Japan). In 1945, the Allies defeated the Axis. Later that year, the victorious nations, in an attempt to prevent more World Wars, founded the United Nations, an international assembly of peaceful nations, whose goal was to settle international disputes peacefully, and was the predecessor to the UNSC. In 1957, Humanity finally made their way into space with unmanned probes and by 1961, Humans themselves had gone into space. In 1969, Humanity had finally stepped on an extraterrestrial surface-Earth's Moon.

After World War II, Humanity would lack war on that scale, although smaller wars and conflicts erupted, including the Korean War, Vietnam War, Cold War, and the Iraq War. In the early 21st century, terrorism became a potential thorn in the side for the nations on Earth and small wars broke out along with civil unrest in many countries. However, no full wars on the same scale as past World Wars erupted.

Interplanetary colonization and conflicts
After years of overcrowding on Earth and the other planets in the Sol System, dissident factions emerged. The Neo-Communist Koslovics and Fascist Frieden, the two major movements, began to battle one another and the United Nations.

In March-June 2160, Jovian secessionists attacked United Nations Colonial advisers on the moon Io, which led to three months of fighting between the Earth military and Jovian Frieden forces. National Governments began to support their own colonies which sparked proxy wars off-planet, leading to tension and militarization on Earth. In 2162 armed conflict ripped through South America, starting the Rain Forest Wars, as Koslovic, Frieden, and UN forces all clashed over ideological differences, sparking additional conflicts off-planet. In December of 2163, the three factions clashed, this time on Mars. This was the first extraterrestrial use of Marines, who launched lightning raids on Koslovics positions, permanently affecting military doctrine for centuries. In 2164 UN forces began a massive military build-up and began the first true interplanetary war. The UNSC was bolstered by a massive propaganda campaign running on the victories on Mars and over the next six years took back the Sol System and drove the dissident factions to destruction. Now with a massive military with no enemy to fight, overpopulation, famine, and a collapsing economy, the newly unified Earth faced an uncertain future.

It was not until 2291 that this problem was solved when researchers created the Shaw-Fujikawa Translight Engine and gained access to Slipspace. In 2310 the UNSC unveiled their first line of colony ships and the best and brightest from both civilian walks of life and the military set out to form the Inner Colonies. This eased the overpopulation problem upon Earth which became the capital of the Unified Earth Government, while the inner colony of Reach would later became the headquarters of the UNSC.

The Insurrection and the Human-Covenant War
Humanity would enter a period of peaceful stability for the next two hundred years, until civil unrest began to spread in the Outer Colonies, with various groups seeking secession from Earth and the UEG. The scale of the unrest would steadily rise, eventually becoming a major threat by 2517 to the UEG's existence, and in response the UNSC began the SPARTAN-II Program.

All this was suddenly and violently rendered a moot point when a single alien ship made an unprovoked attack on the colony of Harvest, humanity's first encounter with an alien civilization - the Covenant. Over the next twenty seven years, Humanity would wage a brutal war for survival, losing hundreds of colonies, including all of the Outer Colonies in 2536; and on August 31st, 2552, the UNSC's largest military installation, the planet Reach, was discovered and invaded by the Covenant. During the entire course of the conflict, the UNSC followed the Cole Protocol, which declared that no UNSC vessel targeted by the Covenant was to retreat to Earth, as a means of ensuring the security of the planet's location.

Despite the effectiveness of this law, on October 20th, 2552, the Covenant launched their first attack upon Earth, initiating the final confrontation between UNSC forces and the Covenant.

Pre-Battle of Earth
Prior to the Covenant invasion of Earth, there had been a suppressed influx of information by ONI, resulting in people going about their normal lives even up until the attack. The forces stationed at Earth were heavy, with the Second Fleet, Seventh Fleet, the Sixteenth Fleet and the 6th Battle Group along with large amounts of Marines, Army Troopers, and ODSTs present, five SPARTAN-IIs, Admiral Hood and Earth's most prominent means of defense, three hundred Orbital Defense Platforms, each sporting a Mk. V "Super" MAC. Also, there were numerous human colonies on various moons, a large naval shipyard and factories at Mars, and a listening post at Io.

Battle of Earth


"The entire population of Earth was cut in half as the first battle of Earth began..."

- Halo Encyclopedia

On October 20th, 2552, the first Covenant forces entered the Sol system. A Covenant expeditionary force consisting of s and Covenant assault carriers arrived in system, first detected around Io, the third largest moon of Jupiter. After the existence of the Covenant presence was confirmed by probes, the UNSCDF forces went to full alert. The option was taken to wait for the Covenant forces to come to them rather than let Fleet Admiral Harper launch a counter attack. The Covenant began to work on punching a hole through the orbital defenses by taking out the stations in the battle cluster above the Mediterranean Sea via bombs planted by boarding parties. After the Covenant fleet attempted to rush through the newly formed gap the UNSC fleet annihilated them, destroying most of the Covenant battlecruisers but failing to destroy the assault carriers. One of the assault carrier, commanded by the High Prophet of Regret, assaulted the city of Mombasa in Kenya.

On the groundside, the Covenant assault carrier had already deployed its ground forces and had already occupied city. The Covenant ground forces immediately constructed defense emplacements and structures to reinforce their newly-acquired sites against the counter-offensive UNSC forces. The was the first UNSC ship to respond to the Covenant occupation. The ship sent in their complements consisting of SPARTAN-II John-117, Sergeant Avery Johnson and elements of the 7th Orbital Drop Shock Trooper Battalion. The Covenant were subsequently dislodged from Old Mombasa and, following the destruction of a Scarab, from New Mombasa as well. The High Prophet of Regret eventually ordered a general retreat and had his assault carrier to initiate a slipspace jump while still over the city. The In Amber Clad followed in the carrier's wake, at the cost of the city being severely damaged by the rupture.

Prior during the event, a contingency of ODSTs were dropped from the to assist the In Amber Clad 's counter-offensive efforts. The slipspace rupture prevented the assist from taking place, plunging the ODSTs into uncontrolled freefall and scattered across the city. However, one particular squad of ODSTs survived and continued their operation in securing the city's infrastructure AI. During the operation, the squad witnessed the arrival of a larger Covenant fleet after escaping the city.

The Covenant returned in force following the Prophet of Regret's abortive attack and Covenant assault forces succeeded in penetrating the orbital defenses. At Mount Erebus, the sea floor off of the the Yucatan Peninsula, and at the Centennial Orbital Elevator in Havana, Cuba, the Covenant were stymied by three SPARTAN-II's, only to have those SPARTAN-IIs get re-deployed to Onyx. However, UNSC forces were unable to repulse and route Covenant landings in Kenya. After breaking Earth's space defenses, the Covenant bombarded Earth in east Africa.

The arrival in-system of SPARTAN-117 in a Covenant-controlled Forerunner Dreadnought, freshly escaped from the Battle of Installation 05, was unexpected. SPARTAN-117 disembarked from the dreadnought in Earth's atmosphere, later recovered by Marines and taken to Crow's Nest. With the aid of the Arbiter, Commander Miranda Keyes, and Sergeant Avery Johnson, SPARTAN-117 breached the Covenant anti-air defenses near the excavated Artifact, clearing the way for an aerial strike on the artifact. The strike was unable to disable the device or prevent the Prophet of Truth from traveling through the portal. After a brief intervention by the Flood a joint Separatist/UNSC force departed through the portal in pursuit.

Following the victory at the Battle of Earth and the Battle of Installation 00, the Human-Covenant War ended in March 2553.
