Pre-Númenóreans are the descendants of the Edain who joined the migration to the West; their relatives who reached Beleriand became the Haladin while they stayed in regions of Middle-earth that would be later settled by the Númenóreans (hence the name).
When the core of their team was pressed to wander on, some Drúedain accompanied them northwards, passing through the Gap of Calenardhon. Many stayed behind because of the dense forest covering the Minhiriath and the western half of Enedwaith between the Greyflood and the Isen and became herd-tenders. Their descendants were peoples in the forests of the shore-lands south of the Blue Mountains, especially in Minhiriath
Their kin of the White Mountains apparently were later driven off (from the most part) by Men of Darkness during the Dark Years, removed to the southern dales of the Misty Mountains and thence some passed into the empty lands until the Barrow-downs, from whom came the Men of Bree.
At the end of the First Age they had spread from Umbar through the White Mountains to Methedras and Dunland, across Enedwaith and Minhiriath and as far North as Cardolan (up to the line from Sarn Ford to the junction of Gwathló and Mitheithel.
The pre-Númenóreans in the White Mountains (between future Pelargir and the Gulf of Lune had refused to join in the rebellion against the Valar and were frequently terrorized and subjected by scattered fugitives from Angband who apparently took in larger numbers to the hills of Rhudaur and the Mountains of Angmar. They were forest-dwellers, scattered communities without central leadership.
In future Gondor they dwelt far from the coasts and the shores of the Bay of Belfalas were still mainly desolate except perhaps for Agar and Edhellond, a small settlement of Elves at the mouth of the confluence of Morthond and Ringló built near a primitive harbour of Pre-Númenórean fisherfolk who fled into the White Mountains in fear of the Eldar
When the Númenóreans returned to Middle-earth, they failed to recognize the forest-folk of Minhiriath as ‘kinsmen’, and confused them with Men of Shadow because their language was not related to Adûnaic
More and more Númenor became a great naval power and the Guild of Venturers established Vinyalondë (early 9th century) The Pre-Númenóreans were patient until the tree-felling by Aldarion became devastating and slowly, hostility was growing and dark men out of the mountains were thrusting into Enedwaith in support of their kinsmen In S.A. 820 Vinyalondë was overthrown by great seas and plundered by hostile men. Men near the coasts were growing afraid of the Númenóreans, or were openly hostile and Aldarion heard rumours of some lord in Middle-earth who hated them. As Gil-galad warned Tar-Meneldur that this instigator was a servant of the Enemy.
Aldarion's successors continued his works and even fought with the pre-Númenóreans until they attacked and ambushed the Númenóreans when they could. They became their enemies giving no thought to husbandry or replanting. The Númenóreans wrecked the banks, the shorelines, great tracks and roads whom they drove into the forests northwards and southwards from the Gwathló and continued battling and destroying what lied ahead of them, pushing into Minhiriath and Enedwaith, establishing themselves inland as far as the river Glanduin (the southern boundary of Eregion), beyond which pre-Númenóreans and hostile peoples lived, a remnant of the peoples that had dwelt in the vales of the White Mountains in ages past The natives overcame their fear of the Elves and fled from Minhiriath into the dark woods of the great Cape of Eryn Vorn (south of the mouth of Baranduin). Those from Enedwaith took refuge in the eastern mountains (Dunland)
Sauron recruited pre-Númenóreans and in the early second millennium he increased pressure on the West, left his stronghold in Rhûn and relocated in Mordor, welcomed by the natives and used the haters of Númenor as spies and guides for his raiders who caused havoc and burned their settlements.
Eriador was already ruined when the Númenórean fleet sent by king Tar-Minastir catched Mordor's troops in the rear and utterly defeated them, but brought peace in the Westlands had peace. The surviving pre-Númenóreans now apparently crossed the Glanduin back south to Dunland which now seemed safer than wrecked Eregion.
In the south the Númenóreans found a useful natural haven already called Umbar by the natives, and then Pelargir in S.A. 2350 and discovered the Men of the Mountains near Dunharrow who eventually repented when Sauron left from Mordor and the power of Gil-galad had grown great
When the Elendili established the Realms in Exile, many Men turned from evil and became subject to them although the pre-Númenóreans were not friendly to them and never learned to distinguish between King's Men and Faithful, while many remembered Sauron's influence. The King of the Mountains first swore allegiance to Gondor
When Sauron returned, Isildur summoned the Men of the Mountains to fulfill their oath, they would not because they were afraid of Sauron. They hid in the mountains isolated till slowly dwindled in the barren hills and became the Dead Men of Dunharrow.
The indigenous Men of Eriador were absorbed by the civilisation of Arnor  By the time of Valandil this mixed population was diminished and there was not enough people to maintain all the places built by Elendil, until eventualy Arnor was split into smaller realms. However when the Hobbits came to Arnor, Númenóreans, allies and enemies were numerous. The númenorean element was stronger in Arthedain and thinner in Rhûdaur until utterly failed. Eventually Angmar was populated by evil men gathered by the Witch-king.
The indigenous Men were also absorbed in the South Kingdom of Gondor, which pursued an expansionistic policy. Gondor's borders were extended by the Ship-kings, subduing the pre-Númenóreans. Their blood was mixed and in the following generations the Dúnedain's power and wisdom was diminished..
Hill-men who practiced magic and from the 14th century on, fortified the hills of Eriador with dark structures harassed Rhúdaur until an evil lord, allied with Angmar, seized its throne and eventually all of Rhúdaur was occupied by evil Men subject to Angmar. The Dúnedain were either slain or fled west. The Angmar War however caused those populations to perish. Cardolan was also deserted and could not be repopulated. Rhúdaur came to be inhabited only by monsters. After the Great Plague, Minhiriath was deserted except a hunters in Eryn Vorn. Other known Mannish settlements included only the Bree-land and the Lossoth in the far North.
As Gondor expanded East and South, the few remote Dunlendings resisted the Númenórean influence and Enedwaith had no such settlements, other than Tharbad. They remained unaffected, independent and even unfriendly to the Dúnedain, holding their own manners and Dunlendish language. However the Dunlendings also remained hostile to those with Orc-blood. The Dunlendings also dwelled alongside the Stoor Hobbits during their Wandering Days and the latter even formed a related language to theirs.
The Dunlendings suffered from the Great Plague less than other peoples owing to their isolation and were still found in the foothills of the Misty Mountains. By the time of the Ruling Stewards they ceased to be subjects of Gondor and, being surrounded by barbarous folk, they moved to settle the region of Calenardhon as its people dwindled during the Watchful Peace.
In T.A. 1944 Calenardhon passed to the Northern Eotheod who came from Rhovanion and were viewed as usurpers by the wild hillmen and Dunlending herd-folk. Kings Brego and Aldor drove the Dunlendings out of Rohan beyond the Isen until Enedwaith. As the ensuing enmity did not concern the Stewards, the Dunlendings kept hostilities to the Rohirrim and attacked whenever the latter were weak or in trouble.
After the death of King Aldor, and as Isengard became more friendly to them, the Dunlendings passed and settled northern Westfold, the mountain glens around the Ring, and southern eaves of Fangorn, becoming openly hostile. This allowed the two peoples to mingle in some peaceful circumstances; and the dark-haired Landlord Freca was said to have Dunlendish blood When it became clear that the raiders were coming from near Isengard, in T.A. 2710 King Déor led an expedition to the north. He found and defeated a host of Dunlendings, but discovered that Isengard was held by hostile forces.
Freca's son, Wulf, allied with the Corsairs of Umbar who were in turn stirred by Sauron, keeping safe his properties at Adorn. Joining his kin from outside of Rohan with enemies of Gondor that had landed in the mouths of Lefnui and Isen, Rohan was invaded from the East, the Isen and Isengard, finally taking Edoras. Gondor, fighting Corsair fleets, could not help. The usurping Dunlendings were reduced after the Long Winter and finished off by Fréaláf. The Rohirrim now kept a strong force in north Westfold.
Eventually many Dunlendings were found later in the west-march, until again Folcwine, aided by Gondor, reconquered it. But the people remaining between Isen and Adorn were largely of mixed blood, and not loyal to Edoras.
Before the War of the Ring, Saruman found in those peoples an opportunity for creating crossbreeds of Orcs and Men. The Dunlendings allied with him and joined his forces in the Battle of the Hornburg. After the War, under King Éomer, there was relative peace.
