This article provides an overview of the history of the United Empire of Earth Navy and its predecessor organisations: the 地球行星聯合國 Navy and 地球聯合國 Navy.
Foundation
The United Nations of Earth Navy (UNEN) was founded on November 8 2380 , when representatives of the armed forces of Earth's constituent nations marched from various points around New York City converging on the UNE Senate building. There, the representatives took an oath that founded the UNE armed forces. This event is commemorated by Pax Humana. The 地球聯合帝國陸軍 is said to be the oldest branch of the armed services, implying they took their oaths first.
Unification Wars
The Unification War was fought between 2380-2384. It began with a mutiny aboard a warship named Stanley. This was the first conflict to involve the UNE armed forces.
Interstellar Police Force
The early UNEN was primarily an interstellar police force, responsible for cracking down on the plethora of criminal organisations that had established bases in remote parts of UNE space, particularly the 克羅肖星系. To combat this threat, the UNEN established a checkpoint around the Sol - Croshaw 跳躍點. The heavy-handed policing of the military led to protests from interstellar hauliers, leading to formation of the civilian 海關局, which took over this role.
First Contact with the Banu
First Contact with the 巴努 occurred in 2438 when a civilian navjumper Vernon Tar came across a fugitive Banu in the 戴維恩星系. While humanity's first contact with aliens was peaceful, the discovery of another technologically advanced sentient race caused the 地球聯合國 to develop their Navy for the potential of meeting a hostile rival.
The 地球行星聯合國 was proclaimed in 2523 as a peaceful restructuring of the 地球聯合國. The Navy was simply relabelled as the United Planets of Earth Navy (UPEN). Ships commissioned under the UPEN carried the prefix UPES, "United Planets of Earth Ship". Vessels serving under the UPEN include the 英仙座-class gunboats UPES Arash and UPES Bunjil as well as the UPES Arrowhead.
Start of the Xi'an-Human Cold War
In 2530, workers from the terraforming company Gaia Planet Services attempted to set up operations in the Th.us'ūng system. They illegally neglected to perform the necessary scans of the system, and unbeknownst to them were attempting to terraform in an inhabited 希安 system. The crew was captured, and following 57 days of negotiations between the 希安帝國 and 地球行星聯合國, released in return for information. This event initiated the Xi'an-Human Cold War, which the UPEN and its successor would be involved in for the next 262 years.
First Tevarin War
In 2541, a jump point to the 塔維因 home system of Elysium was discovered, and the Tevarin encountered. At the time, the Tevarin were an approximately equal race to humanity in terms of technology, and had invented quantum travel and highly advanced 護盾生成器. However, they were also facing issues with overpopulation. As an intensely martial society the Tevarin viewed conquest of the 地球行星聯合國 as a viable solution to their problems, and declared war.
The war would be the first true test of humanity's navy. It culminated in the Battle of Idris IV on October 1, 2544, where under the command of the young Ivar Messer the tide of war was turned against the Tevarin, leading to their eventual defeat in 2546.
