Q. Which river was designated as the western boundary of Nepal with India by the Treaty of Sugauli in 1816?
Answer: River Kali
Notes: The Treaty of Sugauli, signed in 1816, established the River Kali as the western border of Nepal with India. This treaty followed the Anglo-Nepalese War and has led to ongoing disputes over the Kalapani region. The conflict arises from differing interpretations of the border, with Nepal asserting the river as the boundary while India claims a ridgeline to the east of Kalapani.
