Khazad-dûm, popularly known as the ‘Dwarrowdelf ‘or ‘Moria,’ was a subterranean kingdom underneath the Misty Mountains. Khazad-dûm was famous for being the old dominion of Durin Folk Dwarves. It stands as the grandest kingdom that the Dwarves ever constructed.
Inside this heavily arboreal glen, a lengthy sequence of quick waterfalls ran down to the beautiful, oval lake, that seemed to possess an enchanted eminence. "Behold, like jewels placed in the abyss, glinted shining stars, while sunlight pierced the sky from above." Recognizing the stars forming a crest dazzling on top of his head, the great Durin considered it as a fortunate omen, so he gave the lake the name of the 'Mirrormere,' or ‘Kheled-zâram.’ He also named the three mountains towering over the lake: ‘Bundushathûr’ 'Cloudyhead,’ ‘Barazinbar’ 'the Redhorn,’ and ‘Zirakzigil’ 'the Silvertine.' The icy springs near the lake Durin named ‘Kibil-nâla’ (which means the source of the Silverlode), while he called the valley Azanulbizar (Dimrill Dale).
Finally, Durin selected the caves facing east beyond Kheled-zâram being the first early stages of his new bastion. In later days, Durin's people revered all these places foremost, among others. Durin’s descendants built a stone monument carved with runes – Durin's Stone—at the location where he first gazed into Mirrormere. Although at the closing of the Third Age, the monolith had been worn by weather and rendered indecipherable—cracked, faded, and broken—Durin I’s (Khazad-dûm’s founding king) influence, endured for all time. The lengthy reign of Durin I was considered as Khazad-dûm’s golden age. It was fondly regarded to be ‘Durin's Day,’ and that name was also used to refer to the ‘Dwarvish New Year.’
Throughout that time, Dwarrowdelf grew unceasingly in dimension and populace until it developed into the "grandest among the Dwarves mansions," even before Noldor returned to Middle-earth. At that point, Khazad-dûm was then considered "a tale and a name from the verses by the Blue Mountain Dwarves" to the Eldars of Beleriand. Throughout Durin I’s supreme reign, the Dwarves built some of their most magnificent architectural wonders in Khazad-dûm: it’s Second Hall, Durin's Tower, Durin's Bridge, and Endless Stair. The legend of Durin's kingdom went on to intensify long after he died. That is not simply due to the spiritual preeminence he had within the Fathers of the Dwarves being the eldest among them or Dwarrowdelf's ever-increasing size. More importantly, this was due to the realm’s vast riches, which was based upon Mithril: an exceptionally precious metal that was universally valued, but present in no other place apart from distant Númenor lands.
It is not known if they stayed in separate groups or clans inside their new abode or simply melded among the Longbeards. About this period, Orcs then started alarmingly rearming themselves and were vastly numerous, with increasing cruelty, savagery, and recklessness in their assaults. In the ensuing battles, the Orcs outnumbered the Dwarves. Although the Dwarves considered themselves the most formidable warriors among all ‘Speaking Peoples,’ they were pleased to collaborate with Men. A remarkable combination of the horse-mounted archers supplied by Men together Dwarrowdelf’s heavy infantry easily and effectively defeated the Orcs. Thus, the Longbeards eventually dominated the central and northern Hithaeglir, including the eastern lands.
Regardless, the Dwarves of Dwarrowdelf always "considered The Ered Mithrin, the Misty Mountains eastern dales, and the Iron Hills as their land." Ultimately, the Men then helped the Khazad-dûm dwarves "in the organization of the territories that both peoples have secured." The establishment of the great Elven Noldorin kingdom Eregion located west of Dwarrowdelf circa year SA 700, pleasant relations between Elves and the Longbeards were resolutely formed. Several Elves were then concerned in the advancement of Dwarrowdelf's remarkable structures as a result, and it "blossomed more beautifully" all through this time. The close relationship also gave rise to a large westward expansion of the underground dominion of Dwarrowdelf. The inhabitable portions stayed on the eastern side, but passageways were dug through vast distances of rock, ending at a massive stone entrance—the West Gate.
The West Gate stood at the borders near Eregion, and "beckoned out towards their nation and was mainly used by the people." Celebrimbor, ‘Lord of Eregion,’ used ithildin inscription on the gate in honor of the gate’s builder, who was his compatriot Narvi, a great Dwarrowdelf craftsman. The engraving says, ‘Im Narvi hain echant. Celebrimbor o Eregion teithant i thiw hin: "I, Narvi, made them. Celebrimbor of Eregion drew these signs."’ The Elven Lady Galadriel, with her supporters, passed through the West Gate going eastwards across Khazad-dûm/ Dwarrowdelf and found Lothlórien further down the Azanulbizar (Dimrill Dale) valley. Lady Galadriel's regime allowed Nandorin Elves a chance to come back to Lothlórien.
Initially, they had to evacuate the region to flee from Dwarrowdelf 's increasing might. Numerous "brilliant crystal lamps," initially illuminated the entire Khazad-dûm realm, but the halls at the highest levels were similarly lit with shafts and windows hollowed through the mountains. These levels were separated by flights containing fifty or so steps of stone. There were seven levels directly carved from the mountainsides above the ground, and many more underground points—or 'Deeps'—underneath the Great Gates near the opening at the Dimrill Dale. Each level contained a host of arched passageways, pillared halls, and several chambers, often with "dark, smooth, and polished walls seemingly like glass."
Beneath the Gate level is the treasuries, dungeons, and mines. Moreover, lying in the remotest ‘Deep of Khazad-dûm,’ were primeval subways covered in everlasting darkness. These tunnels were thought to have been chewed upon by 'unnamed things' that have inhabited the chasms since the ancient origins of Arda. Only a few (if ever there were) saw these creatures, but there are no existing descriptions of them. A possible exception would be the ‘Watcher in the Water,’ a creature which Gandalf proposed could have arisen from these infernal abuses. A prominent feature in the formidable Khazad-dûm was Durin's Bridge [2], a defensive structure described as "a thin stone bridge, without rail or kerb," that stretched across a chasm of unknown depth and fifty feet in width. The bridge funneled enemy soldiers by allowing them to cross only at a precarious single file, thus slowing their advance and making them easy targets for bowmen.
Another legendary structure is the Endless Stair. It scaled up "from the deepest vault to the greatest summit," where it ended inside Durin's Tower, hewn from the dense stone at the apex of Zirakzigil. Sometime after, Sauron held a profound hatred for Dwarrowdelf and commanded the Orcs to pester Durin's people incessantly. Eventually, and although "the Khazad-dûm halls were too strong and deep and full of people too vast in number and gallant for the dark lord to surmount from without," still "the people started to diminish" as time went by. That was attributed to the deficit of rations that have been previously supplied by Men of the Anduin vales.
Henceforth, the evil being was called Durin's Bane. When the Dwarves left Dwarrowdelf, the once-great kingdom deteriorated and remained empty and dark, except for the presence of a menacing creature lurking in the deep chasms. This was the time the place was renamed Moria or the ‘Black Pit.’ The creature, later known as the ‘Balrog of Morgoth,’ lived alone in Khazad-dum for five hundred years until the place was repopulated, not by its original inhabitants.
The Orcs, menacing creatures taking refuge from the northern parts, started to raid the treasures of the uninhabited city, then opted to inhabit it. The Orcs discovered the Balrog then proceeded to make it their god. Mordor began to send hordes of Cave Trolls and Orcs to colonize Moria, establishing an evil dwelling for the creatures to proliferate. In the Battle of Azanulbizar, a huge number of Orcs were decimated in the area below the east gate of Khazad-dum (circa TA 2799), thus reducing their numbers significantly. However, the Balrog stayed with several Trolls and Orcs with him, keeping Khazad-dûm evil in the meantime. Sometime between circa (TA 2845 - TA 2850), the grey wizard Gandalf ventured into the city in search of King Thrain ll, the one who mysteriously vanished as he journeyed to the Lonely Mountain and its surrounding area.
While inside the mines, the Fellowship traversed through several great halls and passageways until eventually reaching a compartment. There, they found an old dusty book that recounted the last activities of the Dwarves remaining in the realm during the attack of the Orcs. As they were searching the place for the correct path to the exit, Pippin accidentally bumped the armored remains of a Dwarf into a deep well, thus creating a loud noise. Soon, Orcs accompanied by armored cave trolls chased them through the great halls and passages of Moria down to the Endless Stairs and subsequently arrived at the Bridge of Khazad-dûm. As the company crossed the bridge in a single file, the Balrog of Morgoth ascended from the dark pits.
Gandalf valiantly confronted the Balrog, and they dueled in the middle of the bridge, with Gandalf using his sword and staff to block the creature’s lashes of its fiery whip. The two combatants kept at it until they both plunged into the chasm beneath. That act saved the lives of Gandalf's friends, and they mournfully continued out of Khazad-dûm into the vast but comparatively tranquil Dimrill Dale. Meanwhile, the Balrog and Gandalf survived the plummet. Gandalf then chased the fell creature through the Great Stair to Celebdil’s summit, where a climactic battle occurred. Ultimately, Gandalf killed the creature and hurled its carcass down the side of the mountain. Unfortunately, Gandalf succumbed to his battle wounds.
It also showed the Endless Stairs and the Durin’s Bridge (or Bridge of Khazad-dûm) where the company fled from the Orcs, and where the Balrog appeared to attack the company leading to its duel with Gandalf and their eventual plunge into the abyss. The depths of Khazad-dûm are visualized in Frodo's vision sequence at the beginning of the movie ‘The Lord of the Rings: The Two Towers,’ as Gandalf duels with the Balrog as they were falling. It showed the underground caverns where both Gandalf and the Balrog fall and plunge into a subterranean lake.
It must be noted that the opponents fell for a long time, indicating the immense depth of the realm. Khazad-dûm appears again in Peter Jackson's 2012 live-action movie ‘The Hobbit: An Unexpected Journey,’ in a Battle of Azanulbizar flashback sequence, wherein Azog has just killed Thrór and gets defeated by the actions of Thorin Oakenshield.
History
Age of the Trees
“Durin 'the Deathless'” founded the Dwarrowdelf in the remote ancient past, eons before the Moon and Sun were ever created. Durin awoke in Mount Gundabad sometime when the Elves first awakened. Because he was the oldest of the Fathers of the Dwarves, he was duly recognized as the foremost among them. That high status was then passed on to his progenies, the ‘Kings of the Longbeards.’ Durin's flourishing family went down Mount Gundabad and "expanded to the south towards the Vales of Anduin." [1] All this time, "the orcs of Morgoth attacked the whole clan." Legend has it that Durin finally found "a valley of shadows enveloped by two immense limbs belonging to the mountains, and on top of that were three shining white summits."Inside this heavily arboreal glen, a lengthy sequence of quick waterfalls ran down to the beautiful, oval lake, that seemed to possess an enchanted eminence. "Behold, like jewels placed in the abyss, glinted shining stars, while sunlight pierced the sky from above." Recognizing the stars forming a crest dazzling on top of his head, the great Durin considered it as a fortunate omen, so he gave the lake the name of the 'Mirrormere,' or ‘Kheled-zâram.’ He also named the three mountains towering over the lake: ‘Bundushathûr’ 'Cloudyhead,’ ‘Barazinbar’ 'the Redhorn,’ and ‘Zirakzigil’ 'the Silvertine.' The icy springs near the lake Durin named ‘Kibil-nâla’ (which means the source of the Silverlode), while he called the valley Azanulbizar (Dimrill Dale).
Finally, Durin selected the caves facing east beyond Kheled-zâram being the first early stages of his new bastion. In later days, Durin's people revered all these places foremost, among others. Durin’s descendants built a stone monument carved with runes – Durin's Stone—at the location where he first gazed into Mirrormere.

Throughout Durin I’s supreme reign, the Dwarves built some of their most magnificent architectural wonders in Khazad-dûm: it’s Second Hall, Durin's Tower, Durin's Bridge, and Endless Stair. The legend of Durin's kingdom went on to intensify long after he died.

More importantly, this was due to the realm’s vast riches, which was based upon Mithril: an exceptionally precious metal that was universally valued, but present in no other place apart from distant Númenor lands.
First Age
Dwarrowdelf or Khazad-dûm did not play any part during the Beleriand wars and was instrumental in gaining relief from attacking orcs during the First Age, "at the time Morgoth required all his power" somewhere else. The Longbeards continued contact with the other Dwarf clans (numbering six at the time). After the first Men reached Rhovanion, the Dwarrowdelf quickly started bartering with them, trading their masonry skills, and developing metallurgical products for food and other consumables. That significant barter profited both peoples immensely. The ultimate demise of Durin I transpired near the First Age’s closing. Durin was interred in a grand tomb in his beloved Khazad-dûm, forever remembered by generations.Second Age
In the first part of the Second Age, Dwarrowdelf, the Longbeards kingdom, was enhanced in population, skills, and culture by large throngs of refugees coming out of Nogrod and Belegost. These were two great Dwarf cities as well, but they were destroyed in the First Age’s latter part. That coincided with Beleriand’s destruction during the climactic war against Morgoth and the evil ones. The remaining Dwarves in those cities persevered for forty long years beyond the catastrophes, until most of them decided with great difficulty to abandon their homelands and traverse Eriador, on their way to the flourishing and olden Dwarrowdelf (Khazad-dûm). The Dwarves from Nogrod and Belegost are not Longbeards, but Firebeards and Broadbeams.It is not known if they stayed in separate groups or clans inside their new abode or simply melded among the Longbeards. About this period, Orcs then started alarmingly rearming themselves and were vastly numerous, with increasing cruelty, savagery, and recklessness in their assaults. In the ensuing battles, the Orcs outnumbered the Dwarves. Although the Dwarves considered themselves the most formidable warriors among all ‘Speaking Peoples,’ they were pleased to collaborate with Men. A remarkable combination of the horse-mounted archers supplied by Men together Dwarrowdelf’s heavy infantry easily and effectively defeated the Orcs.

The engraving says, ‘Im Narvi hain echant. Celebrimbor o Eregion teithant i thiw hin: "I, Narvi, made them.

That was attributed to the deficit of rations that have been previously supplied by Men of the Anduin vales.
Third Age
As the Third Age began, the Dwarrowdelf Dwarves strove hard to expand their treasure, but the quantities began to decline. The vast bulk of their riches was grounded on the stockpiles of Mithril. This ore they extracted from the deepest mine shafts, and with the passing of the centuries, the Dwarves continued to delve deeper for the prized substance. In TA 1980, they delved too greedily and deeply to obtain Mithril, then to their detriment, they released an unknown terror from the depths underneath their city. The terrible creature brought devastation all over the city, killing almost all the Dwarves, including King Durin VI.Henceforth, the evil being was called Durin's Bane. When the Dwarves left Dwarrowdelf, the once-great kingdom deteriorated and remained empty and dark, except for the presence of a menacing creature lurking in the deep chasms. This was the time the place was renamed Moria or the ‘Black Pit.’ The creature, later known as the ‘Balrog of Morgoth,’ lived alone in Khazad-dum for five hundred years until the place was repopulated, not by its original inhabitants.
The Orcs, menacing creatures taking refuge from the northern parts, started to raid the treasures of the uninhabited city, then opted to inhabit it.

However, the Balrog stayed with several Trolls and Orcs with him, keeping Khazad-dûm evil in the meantime. Sometime between circa (TA 2845 - TA 2850), the grey wizard Gandalf ventured into the city in search of King Thrain ll, the one who mysteriously vanished as he journeyed to the Lonely Mountain and its surrounding area.
Balin's Mission
By TA 2989, the direct progenies (the Longbeards) of the olden Durin Folk inhabiting the Lonely Mountain, kindled an effort to recolonize and regain their ancestral abode - Dwarrowdelf. The mission was headed by Balin ‘Son of Fundin’, a member of Thorin Oakenshield's Company of Dwarves that escorted Bilbo Baggins in his ‘Quest of Erebor.’ He commanded a troop of Dwarves from the Lonely Mountain to Dwarrowdelf, and effectively disemboweled a substantial number of Orcs, seizing most of the halls in the east and repossessing invaluable ancestral treasures like Durin's Axe. Unfortunately, the vastly superior quantity of Orcs overwhelmed their meager company. Sadly, everyone, including Balin himself, died in that TA 2994 battle.Ring of Power
At the time, the Hobbits Sam, Pippin, Merry and Frodo; the Wizard Gandalf; the Elf Legolas; the Dwarf Gimli; and the Men Boromir and Aragorn departed Rivendell on their Quest of the Ring. The group was obligated to journey through Khazad-dûm after their failed attempt to ascend Caradhras (Redhorn) when Wargs chased them. The Fellowship first came upon the west gate, which had many inscriptions only visible when illuminated by the moon. After guessing the Dwelvish riddle to open the west gate, a colossal octopus-like monster arose from the dark waters of the lake and tried to slaughter Frodo. The group killed the monster, but not before it destroyed the entrance, thus trapping them and forcing the group to go deeper into the mines.While inside the mines, the Fellowship traversed through several great halls and passageways until eventually reaching a compartment. There, they found an old dusty book that recounted the last activities of the Dwarves remaining in the realm during the attack of the Orcs. As they were searching the place for the correct path to the exit, Pippin accidentally bumped the armored remains of a Dwarf into a deep well, thus creating a loud noise. Soon, Orcs accompanied by armored cave trolls chased them through the great halls and passages of Moria down to the Endless Stairs and subsequently arrived at the Bridge of Khazad-dûm.

Meanwhile, the Balrog and Gandalf survived the plummet. Gandalf then chased the fell creature through the Great Stair to Celebdil’s summit, where a climactic battle occurred. Ultimately, Gandalf killed the creature and hurled its carcass down the side of the mountain. Unfortunately, Gandalf succumbed to his battle wounds.
Fourth Age
After their banishment from Dwarrowdelf, the Dwarves of Longbeard always had a deep yearning for their ancestral land. Even after the passing of ten centuries and more, they still kept the place close to their hearts and minds. Azanulbizar transformed into "the dark-shadowed vale that we will always remember," just as they felt bound to keep on integrating "the vision of the peaks into several works of stone and metal, and into numerous tales and songs. They remain prominent inside our dreams.." As a consequence of the Balrog’s destruction, the Longbeards, at last, had their long-awaited chance to regain the Dwarrowdelf, and rightfully they did. It is widely held that in some hundred years or so in the Fourth Age, a descendant (and could very well be one of the sons) of Thorin III Stonehelm –Durin VII, was able to lead his kin back to the cherished ancient fatherland. In doing so, they were able to repossess all they could of Dwarrowdelf's wondrous treasures.Etymology
‘Moria’ is a "black chasm"' in the Sindarin tongue. ‘Khazad-dûm’ is "Delving of the Dwarves" in the Dwarvish language.Other names

Khazad-dûm is shown in two film adaptations: First in the 1978 animated movie by Ralph Bakshi ‘The Lord of the Rings,’ and the live-action movie by Peter Jackson in 2001 ‘The Lord of the Rings: The Fellowship of the Ring’ where the interior of the subterranean realm is shown in exquisite detail. The movie showed the west gate with its magical Dwelvish inscriptions, the lake monster attacking Frodo, the great halls, the chambers, and rooms where they found the book documenting the last activities of the Dwarves during the attack of the Orcs.It also showed the Endless Stairs and the Durin’s Bridge (or Bridge of Khazad-dûm) where the company fled from the Orcs, and where the Balrog appeared to attack the company leading to its duel with Gandalf and their eventual plunge into the abyss. The depths of Khazad-dûm are visualized in Frodo's vision sequence at the beginning of the movie ‘The Lord of the Rings: The Two Towers,’ as Gandalf duels with the Balrog as they were falling. It showed the underground caverns where both Gandalf and the Balrog fall and plunge into a subterranean lake.
