|Recharge station(s)||Zenith, Nadir|
The Chesterton system is located near the Tedibyhr and Ulan Batar systems and consists of a class G9V primary orbited by at least five planets. During the thirty-first century recharge stations were in place at both of the system jump points.
The Chesterton system was colonized during the First Exodus from Terra. Chesterton was the capital of one of the earliest interstellar states to form in the Inner Sphere, and remained an administrative capital within several larger states at various points in time.

Chesterton V - more commonly referred to simply as Chesterton - is the fifth planet in the Chesterton system and has five moons named Angela, Iannius, Moira, Nochus and Willus.
The Chesterton colony was founded by Welsh explorer and wealthy trading fleet magnate Tristam Chesterton - also known as Ian Tristram Chesterton - owner of one of the largest trading fleets of the era and a man generally considered to have been the last of the great Welsh space explorers. Chesterton occupied a strategic location close to several systems that were already being developed and had abundant water with which to support colonization efforts; this helped the system become a natural trade crossroads, and by 2193 Chesterton was the center of the newly-founded Chesterton Trade League, a mutual protection pact that began with the worlds of Chesterton and Demeter and which gained new worlds with every passing year. When the Terran Alliance commissioned the Grand Alliance Survey of Populated Worlds in 2235 it was noted that Chesterton didn't consider itself to be even nominally under the authority of the Terran Alliance. At some point prior to 2243 Chesterton and the remaining worlds of the Chesterton nation - variously referred to as the Chesterton Trade League, Chesterton Trade Federation and Chesterton Trade Worlds - joined their sister nation to become one of three provinces in the Tikonov Union, and later the Tikonov Grand Union. Under the Union and then the Grand Union Chesterton served as the capital world of the Chesterton Province. Despite the existence of the Tikonov Grand Union, the former Chesterton nation continued to exist as an independent or semi-independent nation, using the Chesterton Trade Federation name. It was the Chesterton Trade Federation that fought a war with the Federated Suns over the worlds of Beten Kaitos and Emerson between 2318 and 2321.
By 2357 the Sarna Supremacy had absorbed the Trade Federation, including the former capital world of Chesterton. In July 2357 a large force from the Federated Peacekeeping Forces - the armed forces of the Federated Suns - landed on the former Chesterton world of Bell and claimed it in the name of the Federated Suns, with Prime Minister Reynard Davion also demanding that the Supremacy cede the worlds of Chesterton and Highspire to the Federated Suns. The Supremacy had no choice but to comply; Federated Suns troops went on to capture and hold Chesterton in the face of ineffective counterattacks.
Chesterton would remain a Federated Suns world during the era of the Star League, despite a concerted effort by the Capellan Confederation to seize the planet during the border war fought between the two nations from 2760 to 2762. Capellan forces occupied Chesterton, only to find their control of the world hotly contested by the Syrtis Fusiliers; the Capellans were also rejected by the civilian population of the world.
Given the long history of tensions over its ownership, Chesterton was the site and trigger for numerous conflicts during the brutal Succession Wars.
First Succession WarEdit
In 2795, following the appointment of Sandol Quinn as regent to Ilsa Liao, the Capellan Confederation Armed Forces launched an invasion of the Federated Suns intended to capture the politically-significant Chesterton system. Planned by Quinn, the operation was intended to take advantage of the AFFS' continuing focus on trying to resist the massive Draconis Combine invasion of the Federated Suns, which stood poised to capture New Avalon itself. Quinn's plan involved encircling Chesterton by taking the systems around it, using mercenary units for the initial invasions - predominantly or exclusively former Star League Defense Force commands that had been recruited by the Confederation - and following up with CCAF line regiments to reinforce the assault and then secure the captured worlds. Whilst launching one or two planetary invasions aimed at systems around Chesterton, Quinn also had the CCAF copy tactics used by the Combine so effectively, leapfrogging over border systems to capture a number of systems further inside the Federated Suns to add pressure to the AFFS. Quinn's strategy worked well for several years; by 2797 the CCAF had occupied Ogilvie, as well the Branzoll, Carmacks, Salem, Sekulmun and Victoria, creating Capellan "islands" within the borders of the Federated Suns that forced the AFFS to spread it's already-stretched border forces even more thinly at a critical time.
By 2799 The CCAF had seized every world within jump distance of Chesterton, isolating the system, in what had been a remarkably cleanly-fought campaign for the era. Despite isolating the system, Chesterton remained free; although the CCAF had captured or destroyed all of the local jump-capable ships, it lacked the WarShip resources to blockade the system, and Chesteron was a self-sustaining world. Intelligence gathered by the Maskirovka indicated that the the AFFS forces on Chesterton were well-fortified and remarkably well-stocked, having been heavily reinforced by the survivors of other units engaged in the area that had fallen back to Chesterton. Quinn decided to attempt to secure control of the system via diplomacy, sending emissaries to stress how isolated the system was, and the focus the AFFS retained on driving back the Draconis Combine Mustered Soldiery throughout the Federated Suns, making rescue unlikely, and finally the likely level of slaughter that would be involved if the CCAF was forced to invade the world and breach the planetary defenses.
The AFFS response to Quinn's proposals was emphatic, and blunt. The local senior Commanding Officer, Leftenant General Thomas J. King, informed the emissaries sent by Quinn that he had at his disposal a stockpile of cobalt-jacketed nuclear weapons, and that he was entirely intent on unleashing them as soon as any Capellan units began landing on Chesterton. When the emissaries reacted by questioning King's sanity, his reply was succinct: "I know how much your Chancellor loves surprises." Maskirovka investigations were unable to confirm if King actually had the nuclear weapons at his disposal, but those investigations did confirm that the AFFS forces on Chesterton were fanatical in their intention to hold the world, particularly following the news they had received of the massacre on Kentares IV unleashed by Jinjiro Kurita. In isolating Chesterton and destroying or capturing those vessels that the defenders could have used to escape, Quinn hadn't weakened the AFFS' resolve - he had instead convinced them that they had nothing left to lose, and the defenders were both well-disciplined and heavily dug-in. Faced with the certain knowledge that any campaign to capture the world by force would force his own troops to resort to weapons of mass destruction in turn, Quinn ordered his forces around Chesterton to instead maintain a defensive posture while he attempted to come up with an alternative plan of action.
As the First Succession War had dragged on for two decades with the Confederation's military neared exhaustion, Chancellor Ilsa Liao extended a public peace proposal to First Prince Paul Davion, making the startling offer to renounce her claim to First Lordship of the Star League and back him for the position in return for the Federated Suns ceding all claim to Chesterton and the other Chesterton Commonality worlds to the Confederation. With the title of First Lord all but meaningless by this point and embittered by Confederation having profited from the Federated Suns weakness at the start of the war, the First Prince instead immediately and angrily responded by sending the Third and Fifth Crucis Lancers, among the most rabidly anti-Capellan units in the Armed Forces of the Federated Suns, to strike the Confederation, retaking those Chesterton worlds the Capellans had won in the past decade.  
Unable to acquire Chesterton via diplomatic means, Ilsa sent a top secret strike force consisting of four of the CCAF's best regiments to regain the lost Commonality capital in 2811. Unfortunately a MIIO mole in the Maskirovka leaked word of the plan to the AFFS and instead of surprising the Davion troop, the Capellan units were ambushed shortly after landing. While emboldened by fighting on Chesterton's near sacred soil, the outnumbered Capellan troops suffered extremely heavy losses before they reluctantly withdrew, barely two battalions worth of survivors reaching their DropShips to flee. The debacle on Chesteron would be the last major conflict fought by Confederation before the First Succession War finally drew to a inconclusive close in 2821. 
Third Succession WarEdit
The near constant attempts by the Capellan Confederation to reclaim the world damaged the planet's infrastructure and made it difficult for the citizens to live there. During the 3030's and 3040's however the peaceful climate in the Inner Sphere and the technology boom made possible by the Helm Memory Core allowed Chesterton to rebuild much of its infrastructure and industrial capacity. By 3067 the mining and pharmaceutical industries on the world had recovered, as had the ranches that produced meat animals.
During the Jihad, Chesterton was attacked yet again; invaded on the 20th of May 3071, the attackers this time were a group of cybernetically-augmented Thuggee fanatics, operating under the name "Warrior House Rakshasa". The cybernetic enhancements led to speculation that there was a link between Kali Liao and the Manei Domini, and Chancellor Sun-Tzu Liao later denied authorizing an attack on Chesterton. Warrior House Rakshasa then left Chesterton as unexpectedly as they'd arrived, lifting off on the 17th of June.
The Dark AgeEdit
In December of 3144, Operation CELESTIAL REWARD saw the capture of Chesterton by the Fifth McCarron's Armored Cavalry and Second Tikonov Guards from the Federated Suns. The defending Twelfth Vegan Rangers retreated to Ulan Batar rather than face destruction. The capture of Chesterton and surrounding worlds has resulted in the reformation of the Chesterton Commonality and the reinstatement of the Hargreaves Family as hereditary rulers.
