Pipphalivana was the capital of the Moriya republic, a gana- sangha of the Mahajanapada period.
[4][5][5][3] Buddhist texts like the Dīgha Nikāya and Buddhavaṃsa suggest that Pipphalivana was the chief town and capital of the Moriyas.
Some say that Pipphalivana probably lay between Rummindei (Lumbini) in the Terai region of Nepal and Kasia in the modern-day Gorakhpur district.
[3] The town is identified with Nyagrodhavana (banyan grove), a village in Gorakhpur district which contained the famous Embers' stupa and was mentioned by Hiuen Tsang.
[2][4] A tradition explains that the Moriyas took refuge in a pipphalivana (grove of pepper trees) and founded the city Moriyanagara there.
