AHC: Buddhist Crusade?

[Rush Tarquin]

We already had that in Sri Lanka. Buddhist clergy made the most anti-Tamil speeches during the civil war.

I think the OP was looking for an empire using Buddhism to conquer the lower Ganges Valley.

Yeah, so I was envisioning some crack future history TL involving a Burma-Bangladesh War that could fulfil the letter if not the spirit of the challenge.

In Mongolia there was existed understanding of "Buddhist religous war". It called "Шамбалын дайн" or "Shambala War". It was used by lama's during 1930's rebellion of Mongolian lama's.

Or perhaps a popular AH go to, an OP Mad Baron in Mongolia TL.

History has not recorded any religious war led by Buddhist countries. The Buddhism has always spread peacefully. I think that Buddhism do not consider spreading the religion through sword or force as meritorious. The Buddhist kings have fought wars against kings of other faiths but the reasons were more political than religious.
The conflicts in Sri Lanka and Myanmar are more ethnical than religious. In Sri Lanka it is Sinhala ethnicity rather than Buddhist Faith that drives even the Buddhist monks on the path of aggression. In Myanmar it is Burmese nationalism that turns the Buddhists against the Muslims viewed as the Bangladeshi immigrants even if they were Burmese citizens for decades.
