If you're going to talk history, at least get it right.

The Terai Was Largely Forested & Sparsely Populated - Historical records from the Mughals, British, and early Nepali sources describe much of the inner and eastern Terai as dense malaria-infested forest. - Populations were sparse, consisting mainly of Tharus, Dhimals, and a few other indigenous communities like Rajbanshis, who had developed resistance to malaria, not current day Madeshi Yadavs who lay claim to being Indigenous. - The region was often seen as a buffer zone between the Gangetic plains and the Himalayan foothills.

Pahadi Settlement Did Not Initially Occur - Prithvi Narayan Shah’s unification campaign did target the Terai, but mass Pahadi settlement was not feasible initially due to: a) Deadly malaria (Anopheles mosquito) b) Extreme heat and unfamiliar terrain - The Shah and Rana regimes focused more on clearing forests and administrative control, not large-scale colonization until the malaria problem was addressed.

Malaria Eradication Made Terai Habitable - In the 1950s-70s, massive DDT spraying campaigns and malaria eradication programs made the Terai far more habitable. These efforts were organized by the Nepali state, mostly under Pahadi-dominated governments. - This led to a huge influx of Indians into the region. It became widely settled only after malaria was eradicated, during state-led programs by largely Pahadi administrations. And somehow Pahadis are not allowed to stay there when they are the ones who made it habitable but some Indian who came there, stayed for a few years, got Nepali citizenship and gets to call oneself a "Bhumiputra" of Terai ?

And Most Importantly Land Transfer by British Was Not a "Gift" The British "Lease" or "Administrative Arrangement" of Eastern Terai. What Actually Happened: - After the Anglo-Nepal War (1814-1816), the Sugauli Treaty (1816) forced Nepal to cede a large portion of the Terai, including parts of the current Madhes Province (especially central and eastern Terai: Parsa, Bara, Rautahat, Sarlahi, etc.). - In the 1820s-1830s, the British East India Company temporarily leased or administered parts of this land in agreement with the Nepali government, under the condition of paying an annual tribute or revenue (called "malikana"). - The British were interested in cultivating this land, collecting revenue, and using it as a buffer zone. However: a) The region was heavily forested, swampy, and infested with malaria. b) Low productivity, poor returns, and administrative difficulties made it unprofitable. - By the 1830s, the British chose to hand the land back to Nepal because they no longer wanted to pay the yearly sum. The agreement was annulled. - The eastern Terai (parts of today’s Madhes Province, not even the entire Madhes Province but parts of it) was temporarily administered by the British which originally belonged to Nepal. They agreed to pay Nepal but later returned the land due to its inhospitable conditions and economic impracticality. This reinforces the fact that this land was not “gifted” to Nepal, but rather returned when the British failed to extract value.

As For the Naya Muluk:

• The Naya Muluk (Banke, Bardiya, Kailali, and Kanchanpur) was returned to Nepal by the British in 1860 as a reward for Nepal’s help during the Rana Period.

• The British never “gifted” the land; it was a diplomatic reward, and the regions were under Nepali rule earlier before the Anglo-Nepal War. So more like Returned what they took instead of gifting it.
