The '''ecumene'''<!--"Ecumene" is written in lower case throughout all novels in The Forerunner Saga. It does not seem to be a proper noun.--> is the translated name for the [[Forerunner]] empire which existed over 100,000 years ago. It stretched across [[Milky Way|the galaxy]] and consisted of three million habitable worlds at its peak.<ref name= "cryptum">'''[[Halo: Cryptum]]''', ''page 9''</ref> The political center of this empire was known as the [[Maethrillian]], the Capital city, a massive planetoid structure containing multiple cities. Maethrillian itself was located in the [[Orion complex]], which was considered to be the center of the ecumene. This region of space was bordered by the [[Maginot Sphere|Jat-Krula]], often translated as the "Maginot Sphere", a defensive boundary consisting of millions of [[Line installation]]s.<ref name="silent104">'''[[Halo: Silentium]]''', ''pages 104-105''</ref>

==History==
===Early history===
The ecumene was established sometime before [[10,000,000 BCE]], centered in the [[Orion complex]]. At one point the [[Precursor]]s made a decision to pass down the [[Mantle]] to [[human]]s instead of the [[Forerunner]]s. Although the specifics and causes of the events are unclear, the Forerunners [[Forerunner-Precursor war|furiously rebelled]] against the Precursors,<ref>'''Halo: Silentium''', ''String 24''</ref><ref>'''[[Halo: Primordium]]''', ''page 194''</ref> eventually leading to the latter retreating to [[Large Magellanic Cloud|Path Kethona]], outside the galaxy. However, several Forerunners followed with an enormous fleet of warships. A majority of the Precursors were eradicated by the following Forerunners. The Forerunners responsible for the near-genocide were unable to bear the burden of what they had done. Ashamed, many of them exiled themselves on a barren planet located in the [[Tarantula Nebula|Spider]].<ref>'''Halo: Silentium''', ''String 15''</ref> The [[Builder]] and the [[Warrior-Servant]] commanders of the ecumene worked to suppress the truth and realities of the war. Any individual that attempted to learn of the past was silenced or exiled to a [[Cryptum]].<ref>'''Halo: Cryptum''', ''page 362''</ref><ref>'''Halo: Silentium''', ''pages 67-68''</ref>

Now the dominant race in the galaxy, the Forerunners and their ecumene began to expand. This often resulted in several sapient species being forcibly relocated from their homeworlds to allow the ecumene to colonize the world.<ref name="cryp112">'''Halo: Cryptum''', ''page 112''</ref> Over the course of their history, the ecumene experienced a number of civil wars, one of which took place over half a million years before their war against the Flood. To safeguard the Orion complex—the center of the ecumene's governance—during these conflicts, the Forerunners constructed the [[Maginot Sphere]], an immense array of defensive installations spread out in a sphere which completely surrounded the Orion complex.{{Ref/Reuse|silent104}} During these civil wars, the Builders slowly made themselves the political leaders of the ecumene, rising to supremacy and removing the cultures of the Warrior-Servants and the [[Miner]]s.<ref name="silent119">'''Halo: Silentium''', ''page 119''</ref>

The [[Capital]], the center of the ecumene and the seat of the [[Ecumene Council]], was constructed around [[122,990 BCE]].<ref>'''Halo: Cryptum''', ''page 296''</ref> At some point, the ecumene fought a series of bloody civil wars known as the [[Kradal conflicts]] in the galactic center.<ref>'''Halo: Silentium''', ''page 246''</ref><ref name="warlord">'''[[Halo 2: Anniversary]]''', multiplayer map ''[[Warlord]]'' (map description)</ref>

===War with humanity===
[[File:H4-Terminal-HumanShip-Bridge.jpg|thumb|300px|[[Forthencho]] orders his crew to orbitally bombard a Flood infested ecumene world.]]
{{Main|Human-Forerunner wars}}
By [[150,000 BCE]], the ecumene was the largest empire in the [[Milky Way]].<ref>'''[[Halo Encyclopedia (2009 edition)]]''', ''page 26''</ref> The expansion of the ecumene began reaching human space. Looking to escape from the Forerunners' dominion, [[Prehistoric human civilization|the human empire]] expanded throughout the [[Orion Arm]] and eventually built an impressive empire consisting of at least 20,000 worlds in a thousand systems, rivaling the might of the ecumene.<ref>'''Halo: Primordium''', ''page 129''</ref>

When the human empire was at war with the [[Flood]], human fleets under the command of [[Forthencho]], Lord of Admirals were sterilizing planets, home to other species, with Flood infestations. When worlds in the ecumene began to become infected by the Flood, they were immediately targeted for [[orbital bombardment]], killing millions of Forerunners in the process. The Forerunners did not believe that the Flood was a credible threat to the ecumene and began attacking humanity in response, believing that the humans were attacking other worlds to expand.<ref name="terminals">'''[[Halo 4]]''', ''[[Terminal (Halo 4)|Terminals]]''</ref> While the humans were successful at holding their own against the Forerunner military, despite also fending off the Flood, humanity never came closer than 15,000 light-years of the Orion complex.<ref>'''Halo: Primordium''', ''page 311''</ref>

The Forerunners took control of numerous former human colonies in the war, expanding the ecumene. Humanity's homeworld, [[Earth|Erde-Tyrene]], was one of the first planets taken from the human empire, while its neighbouring planet, [[Mars|Edom]], was used as a mining colony.<ref>'''Halo: Primordium''', ''page 237''</ref> The [[San'Shyuum]]'s [[San'Shyuum home system|home system]] also became encompassed by the ecumene, with the ''[[Deep Reverence]]'' orbiting [[Janjur Qom]] to ensure the species' exile on their homeworld for aiding humanity throughout the war.<ref>'''Halo: Cryptum''', ''page 144''</ref> Eventually, after [[Siege of Charum Hakkor|a fifty-year standoff]] at [[Charum Hakkor]], the human empire was defeated by the ecumene's military. As punishment for the human's crimes, the Ecumene Council ordered the species' regression to a [[Erde-Tyrene civilization|pre-technological state]].<ref>'''Halo: Cryptum''', ''page 45''</ref>

===Forerunner-Flood war===
{{Main|Forerunner-Flood war}}
[[File:H4-Terminal-Flood-Fleet.jpg|thumb|300px|A Flood-infested fleet over an ecumene world.]]
After the war with humanity, the possible threat of the [[Flood]] was realized by the ecumene government. This led to a split in the ecumene's politics, with the [[Master Builder]] [[Faber]] and the [[Ecumene Council]] wishing to construct the devastating [[Halo Array]], while the [[Ur-Didact|Didact]] and his [[Promethean]]s favored the [[shield world]]s. Eventually, Faber won the political battle and the Didact was exiled from the ecumene. The construction of the Halo Array began shortly after.{{Ref/Reuse|silent119}} Roughly nine thousand years after their war with the humans, [[Seaward]], a Forerunner isolationist colony on the edge of the ecumene, was attacked by the Flood. This began the galactic war that eventually led to the dissolution of the ecumene. The Flood began to infect thousands of Forerunner worlds, leading to the deaths of billions of Forerunners and other sapient species. The highest levels and tiers of the Forerunner Fleet Command began to realize that Forerunner species' extinction was plausible.<ref name="h3terminals">'''[[Halo 3]]''', ''[[Terminal (Halo 3)|Terminals]]''</ref> While the Halo Array's construction was completed, the Ecumene Council remained reluctant to activate them. During a [[San'Shyuum]] [[Battle of Janjur Qom|rebellion]] on their homeworld, Faber fired [[Installation 07]] on the planet, nearly eradicating the entire species. Faber and the Halo Array were brought back to the [[Capital]] and Faber was stripped of his title and powers. This led to the Ecumene Council undergoing a radical change, with most of its [[Builder]]-aligned members being replaced by younger [[Councilor (Forerunner)|councilors]].<ref name="silent264">'''Halo: Silentium''', ''page 264''</ref>
[[File:HaloFiring.png|thumb|300px|left|The firing of the [[Halo Array]] throughout the ecumene.]]
While the Halo Array was deemed too destructive and were to be decommissioned at the Capital, the Flood led by the defected command and control AI [[Mendicant Bias]] [[Battle of the Capital|invaded]] the Capital system aboard Installation 07.<ref>'''Halo: Cryptum''', ''page 300''</ref> The battle led to the loss of the Capital and the deaths of many political commanders in the ecumene when Installation 07 was fired.<ref>'''Halo: Primordium''', ''page 272''</ref> In the final years of the war, over 500,000 star systems were infected by the Flood. The Flood soon controlled two-thirds of the ecumene; these areas were referred to as [[Burn]]s.<ref name="string20">'''Halo: Silentium''', ''String 20''</ref> Eventually, the Forerunners began relying on the [[Maginot Sphere]], which only protected the ecumene's core worlds in the [[Orion complex]]. This left the rest of the ecumene to fend for themselves.{{Ref/Reuse|silent104}} 

When the Orion complex became overrun by the Flood, ecumene command retreated to the greater Ark along with the remaining Forerunner population. While small pockets of survivors still existed throughout the ecumene, the greater Ark was now the Forerunners' last bastion, housing the rest of the ecumene's military and political commanders.<ref>'''Halo: Silentium''', ''page 245''</ref> The ecumene's leadership decided that the only remaining option was to fire the remaining Halo installations, stopping the Flood before it could expand beyond the galaxy. Soon after this decision, the Flood [[Battle of the greater Ark|attacked the greater Ark]] and destroyed it. With most of the Forerunner leadership and population dead, the few surviving Forerunners led by the [[IsoDidact]] journeyed to [[Installation 00]], the lesser Ark, its location still hidden from the Flood. The IsoDidact had the Halos distributed across the galaxy and activated the rings, killing all sentient life of sufficient biomass in the Milky Way, including any surviving Forerunners within the range of the Halo effect.<ref>'''Halo: Silentium''', ''page 332''</ref>

===Dissolution===
The IsoDidact and numerous [[Lifeworker]]s present on Installation 00 survived the firing of the Halo Array. The lifeforms sheltered on the Ark were eventually returned to their homeworlds and reintroduced them to their native ecosystems, now free of the Flood. After the re-seeding effort was finished, the surviving Forerunners left the galaxy, vowing to exclude themselves from the affairs of other species out of guilt over their failure as galactic custodians.<ref>'''[[Rebirth]]'''</ref>

100,000 years later, between [[2557|July 22]] and [[2557|July 24, 2557]], the Ur-Didact repeatedly contacted [[Catalog]] via a node located on [[Mars]] and asked to take control of the ecumene; Catalog rejected his requests.<ref>[https://forums.halowaypoint.com/yaf_postsm2963929_Catalog-Interaction.aspx#post2963929 '''Halo Waypoint''': ''Catalog Interaction'']</ref>

==Government and politics==
[[File:EcumeneCouncil.png|thumb|300px|The [[Librarian]], [[Ur-Didact|Didact]], and [[Faber]] before the Council, three influential political individuals.]]
{{Quote|The ecumene has become confused. The Council steeps itself in lies and dishonor.|The [[Ur-Didact|Didact]] on the corruption in the ecumene and the Old Council}}
The primary governing body of the ecumene was known as the [[Ecumene Council]]. Based in the [[Capital]], it was led by the [[First Councilor]], composed of five hundred [[Councilor (Forerunner)|councilors]] from various [[rate]]s, and supported by a network of [[ancilla]]s known as the [[Metarchy|Council metarchy]].<ref>'''Halo: Cryptum''', ''page 292''</ref> The ecumene's primary judicial institution, known as the [[Capital Court]], which could be assembled into the [[Supreme Mantle Court]] in times of great crisis.<ref name="crypt264">'''Halo: Cryptum''', ''page 264''</ref> After the [[Master Builder]] [[Faber]] used [[Installation 07]] to [[Battle of Janjur Qom|quell a rebellion]] that resulted in the deaths of a majority of the remaining [[San'Shyuum]], a revolutionary party of younger councilors opposed to the Master Builder took command of the Ecumene Council.{{Ref/Reuse|silent264}} A majority of the Council was replaced by new, mostly younger, councilors that were appointed through brevets.{{Ref/Reuse|crypt264}} This Council became referred to as the "New Council", while the one led by Faber was referred to as the "Old Council".<ref name="s18">'''Halo: Silentium''', ''page 18''</ref>

The [[Juridical]] rate was charged with investigating criminal actions by citizens of the ecumene, as well as preventing crimes from being committed. The head of the Juridical rate was known as the [[Master Juridical]].<ref>'''Halo: Silentium''', ''String 1''</ref> Around [[97,445 BCE]], the Juridical rate was effectively shut down due to the capture of several Juridicals by the [[Flood]]. The Flood used the captured Juridicals to access access the Juridical network and spread the [[logic plague]] to [[Catalog]] and [[ancilla]]s. As a result, Forerunner legal proceedings in the ecumene were put on hold indefinitely.{{Ref/Reuse|string20}}

In the final years of the ecumene, corruption began to encompass even the legal Juridical rate. The [[Builder]] rate, led by Faber, gained control of the Old Council and Faber ruthlessly eliminated all of his opposition in positions of power.<ref>'''Halo: Silentium''', ''page 29''</ref> The corrupt Juridicals ensured the Master Builder's political dominance among the ecumene and allowed him to pursue his own agenda.<ref>'''Halo: Silentium''', ''String 2''</ref> Ultimately, due to Faber's ruthlessness at [[Janjur Qom]], he was temporarily stripped of his power, although his political power was restored during the Flood's [[Battle of the greater Ark|attack on the greater Ark]].<ref>'''Halo: Silentium''', ''String 33''</ref>

==Military==
[[File:H4 - Warrior-Servants.jpg|thumb|300px|A squad of Warrior-Servants during the [[human-Forerunner wars]].]]
A majority of the ecumene's military consisted of the members of the [[Warrior-Servant]] rate, traditionally tasked with defense and warfare in the Forerunner ecumene.<ref name="glossary">'''[[Halo Waypoint]]''', ''[[Halo: Cryptum/Glossary|Halo: Cryptum glossary]]''</ref> Despite this, the Warrior-Servants stood second-lowest in the hierarchy of rates, only higher than the [[Huragok|Engineers]]. The individual with the rank of [[protector of the ecumene]] was considered the commander of the Forerunner military and was historically held by a high-ranked Warrior-Servant. The [[Ur-Didact|Didact]] held this title for twelve thousand years, during the Forerunner conflicts with [[human]]ity and the [[Flood]]. His successor, the [[IsoDidact]], held the title in the final years of the ecumene.<ref>'''Halo: Cryptum''', ''page 233''</ref> The highest and most respected class of Warrior-Servants were known as the [[Promethean]]s.<ref>'''Halo: Cryptum''', ''page 54''</ref> Additionally, the [[Builder]] rate had their own private military under the influence of [[Master Builder]] [[Faber]], known as [[Builder Security]]. Builder Security often had more advanced weaponry and warships than the Warrior-Servants.{{Ref/Reuse|glossary}} After the Didact went into exile for the first time, Builder Security almost entirely supplanted the Warrior-Servants, with most former Warrior-Servants joining their ranks after their own rate was diminished.<ref name="string 3">'''Halo: Silentium''', ''String 3''</ref> The Warrior-Servant rate was partly reconstituted near the end of the Forerunner-Flood war, although their forces were virtually merged with those of Builder Security.<ref>'''Halo: Silentium''', ''page 197''</ref>

[[File:H4-Terminal-Didact.jpg|thumb|250px|left|The [[Ur-Didact|Didact]], [[protector of the ecumene]] for twelve thousand years.]]
In battle, military personnel wore varying types of fighting suits—[[combat skin]]s—the [[war sphinx]] or [[Seeker (vehicle)|Seeker]] combat suit variants being examples of a medium-sized suit.<ref>'''Halo: Cryptum''', ''page 43''</ref> The Warrior-Servants once operated the ecumene's most prominent [[Forerunner fleet|battle fleets]], comprising warships such as {{Class|Fortress|vessel}}s, [[Forerunner dreadnought|dreadnoughts]], [[planet-breaker]]s, and [[Forerunner picket cruiser|picket cruisers]]. Support by [[ancilla]]s and copious amounts of robotic drones — including [[monitor]]s, [[sentinel]]s and [[weapon-ship]]s — was a key component of Forerunner warfare,<ref>'''Halo: Cryptum''', ''page 139''</ref><ref>'''Halo: Silentium''', ''page 214''</ref> along with their weaponized use of the higher dimensions of [[slipstream space]].<ref>'''Halo: Silentium''', ''page 211''</ref> This usage of slipspace culminated in a strategy known as "[[Clench]]", using non-linear causality and probability manipulation to influence the outcomes of interstellar warfare.<ref>''[[Halo: Warfleet – An Illustrated Guide to the Spacecraft of Halo|Halo: Warfleet]]'', Glossary (p. 90)</ref>

During his numerous efforts to combat the [[Flood]] through military force, the Ur-Didact used the [[Composer]], a Forerunner machine capable of digitizing organic consciousnesses, to covert his Prometheans into powerful robotic forms, known as [[Promethean Knight]]s. Although these Knights were an ideal strategy to fight the Flood without risk of biological infection, there were not enough of them to rid the galaxy of the parasite.{{Ref/Reuse|terminals}} To aid in their conflicts against the Flood, Faber and the Didact had created [[Mendicant Bias]], a [[Contender-class artificial intelligence|''Contender''-class]] ancilla to coordinate all of their strategic military movements against the Flood; however, the AI later defected to the parasite's side.<ref>'''Halo: Silentium''', ''pages 186-187''</ref> In the final battles of the war, the ecumene's military became a very loose entity with little organization. The remaining Forerunner military and political commanders were killed during the Flood's [[Battle of the greater Ark|assault]] on the [[greater Ark]], with only the IsoDidact surviving and leading the last of the ecumene.<ref>'''Halo: Silentium''', ''String 36''</ref>

{{Quote|I thought the Forerunners didn't need new planets—that we'd achieved maximum growth?|[[IsoDidact|Bornstellar]], surprised to learn that the ecumene was still expanding}}
The ecumene once encompassed three million fertile worlds in the [[Milky Way|Milky Way Galaxy]].<ref name= "cryptum"/> The core worlds of the ecumene where located in the [[Orion complex]]. The Forerunners primarily divided the ecumene into [[thema]]s, whose borders were marked by galactic magnetic fields,<ref>'''Halo: Silentium''', ''pages 234-235''</ref> as well as segments known as [[margin arc]]s.<ref>'''Halo: Silentium''', ''page 77''</ref> Divisions of the ecumene were overseen by [[regional commandant]]s.<ref>'''Halo: Silentium''', ''page 195''</ref> The territory of the ecumene encompassed not only the worlds of the Forerunners themselves, but also the various subject species that lived under their rule.<ref>'''Halo: Primordium''', ''page 156''</ref> Years prior to the [[human-Forerunner wars|conflicts with humanity]], the ecumene had began expanding towards the galactic center. Wishing to develop in isolation from other species, the Forerunners moved native populations from their home regions to newer, outer systems.{{Ref/Reuse|cryp112}} When the ecumene borders began expanding close to the [[Sol system|Erde-Tyrene system]], the [[prehistoric human civilization|human empire]] moved their civilization from their homeworld to outward along the [[Orion Arm]], likely to flee from Forerunner control.<ref>'''Halo: Cryptum''', ''page 20''</ref> At the height of their power, billions of Forerunner starships plied goods and ferried passengers between the stars, and enforced their vision of peace on the galaxy.<ref>'''[[Halo: Warfleet]]''', ''page 8''</ref>

The population of the ecumene's worlds varied greatly. Some planets, such as [[DM-3-1123 b]] and [[LP 656-38 e]], had populations numbering in the billions.{{Ref/Reuse|h3terminals}} The [[Warrior-Servant]] world [[Nomdagro]] was home to a million inhabitants.<ref>'''Halo: Silentium''', ''page 49''</ref> [[Bornstellar Makes Eternal Lasting]]'s wealthy Builder family personally owned an [[Bornstellar's homeworld|entire planet]] that was also inhabited by a number of subservient Builders.<ref>'''Halo: Cryptum''', ''page 230''</ref>
