The Mahûd was shown in Peter Jackson's The Lord of the Rings. The title and description itself was invented for the Lord of the Rings Strategy Battle Game to describe the trainers and riders of the Mûmakil. It has obvious connections with the real world name for elephant riders- Mahout. See the quote below.
- "The Mûmakil are not native of the arid land of Harad, but come from the savannahs even further afield. The Men that live there, a mysterious and fierce race of deadly hunters known in Harad as 'the Mahûd', were the first to tame the Mûmakil. The tribal leaders of the Mahûd can develop such a strong empathy with these animals that they are said to even be able to talk to them. For this reason, the wealthiest Haradrim leaders go to great length to hire the services of a Mahûd Chieftain to command their Mûmak into battle."
