Gorkha Invasion Dates — 1791–1815: think "1791 = 17 years before Waterloo (1815)" to anchor both start and British intervention ending Gorkha rule.
Chand Dynasty Span — 10th–18th century = 8 centuries; mnemonic "Chand CHA-nd = 8 letters (Hindi cha-aath)" for rough duration of Kumaon's longest dynasty.
British Kumaon-Garhwal Split — After 1815, British got Kumaon; Garhwal split into British Garhwal (east) and Tehri princely state (west). Remember "K-East, T-West" (Kumaon Easier to control, Tehri Western princely).
