The Great Plague, also known as the Dark Plague was a disastrous pestilence that killed untold numbers of people, possibly up into the hundreds of thousands. The plague was brought by an evil wind from the east. It concided with a Shadow deepening in Mirkwood, and the reappearance of evil things.[1]

The effects of the plague; more intense color shows worse effect (based on interpretation in the Atlas of Middle-earth.

The Great Plague began in the east beyond Mordor and hit Rhûn and Rhovanion, and after it had passed, more than half the folk of the Kingdom of Rhovanion had been killed[2]. The Plague also hit the enemies of Gondor, otherwise they could overwhelm the weakened kingdom easily, but this didn't affect Sauron, who could wait.[1]

It first reached Gondor in T.A. 1636 (just a couple of years after King Minardil had been killed at Pelargir by the Corsairs of Umbar). The Plague was devastating in Gondor; Osgiliath was especially hit hard, suffering the highest casualties outside of Rhovanion. Many fled the city and removed to Ithilien and Anórien, and Minas Anor became the King's seat. The casualties were so high that the fortresses guarding Mordor were abandoned as the troops were recalled.[1] The new king, Telemnar was killed together with his kin, followed by the White Tree of Gondor, as well as many others of the Dúnedain;[3] two centuries after the Kin-strife, this further destroyed the people of Gondor.[1]

From there the plague spread west and then north, making Eriador desolate.[3] Dunland suffered less from the Plague than most due to their self-isolation.[4] However, the Plague regained strength as it went north, and Minhiriath (the southern part of Cardolan) was especially hit hard. The joint garrison (of the North and South Kingdoms) at Tharbad ceases to exist.[5] The last of the Dúnedain of Cardolan died on the Barrow-downs, and evil spirits from Angmar and Rhudaur entered the realm.[6]

While the Shire suffered greatly,[3] the plague lessened passing northward until the northern part of Arthedain was scarcely affected.[6] Arthedain still defended Fornost Erain to the north.

The Plague marked the beginning of the desolation of Eriador,[3] that continued being depopulated from Men for the rest of the Age.[7] The exact date the plague ended is not known but for the next two centuries Gondor, as well as its enemies, did little but try and regain strength. Historians believed that the Plague was caused by Sauron since the Shadow deepened in Mirkwood, foretelling his return in the (now unguarded) Mordor.[1]

[edit] Portrayal in adaptations

2015: The Lord of the Rings Online:

The Great Plague is revealed to be an evil of Sauron, created by his chief poisoner Lhaereth the Stained. Various versions of it were tested in Rhun before a suitable variant was unleashed onto the lands in the west. However, despite the devastation it brought, the Plague was deemed a failure by Sauron for not being deadly enough, and Lhaereth fell out of his favor for many years hence. It is revealed that the Rangers of the North could heal those affected by the Plague with kingsfoil. After the downfall of Sauron, the player works with two Rangers to stop Lhaereth from unleashing a new, improved version of the Great Plague.
