Sino-Nepalese War — Nepal Defeated by Qing China

What happened

Nepal tried to expand into Tibet but China sent a huge army that nearly reached Kathmandu. Nepal had to agree to pay tribute to China and stop attacking Tibet. This set Nepal's northern boundary and its relationship with China for over a century.

Full Verified Record

Nepal invaded Tibet in 1788 and again in 1791, looting Tashilhunpo Monastery. China's Qing Emperor Qianlong sent a 70,000-strong army through Tibet into Nepal. The Chinese forces advanced to within a day's march of Kathmandu before Nepal sued for peace. The 1792 treaty forced Nepal to pay a triennial tribute to Beijing and accept tributary status — a relationship that was formally maintained until 1908. The war established China's military capacity to project power into Nepal and ended Nepal's aggressive expansion northward.

नेपालले १७८८ र १७९१ मा तिब्बतमा आक्रमण गरेपछि चीनले ७०,०००को सेना पठायो। नेपालले शान्ति प्रस्ताव गर्यो र चीनलाई श्रद्धाञ्जलि दिने सन्धिमा हस्ताक्षर गर्यो।

Why it mattered

The war ended Nepal's northward expansion and established China as Nepal's northern security guarantor. The tributary relationship lasted until 1908. It also hardened Nepal's view of its vulnerability between powerful neighbors — the 'yam between two boulders' reality Prithvi Narayan had warned about.
