[Lord of the Rings] What happened to Mordor and the Orcs after the end of the War of the Ring?
gpt
Mordor was conquered by Aragorn in his campaign to eee re-claim lands lost to Arnor (he was crowned king of Gondor and Arnor) - just to put it in a timeline context - this makes about as much sense as if Italy started to re-claim Europe bcs of the roman empire.

As for the Orcs without Sauron's unifying presence to guide their action, they scattered unable to organise on a larger scale never to be a significant threat again, with Aragorn's forces killing whatever stronghold of theirs they found on their 're-unification' campaign.
