The history of Thoubal is deeply intertwined with the legacy of the Kingdom of Kangleipak (Manipur). For centuries, the region was an important agricultural and strategic corridor in the Imphal Valley, inhabited primarily by the Meitei people. Traditional folklore and local texts often reference the rivers and lakes of Thoubal as vital sources of life and commerce for the ancient kingdom.
Thoubal's most defining historical moment occurred during the Anglo-Manipuri War of 1891. Just south of the city lies Khongjom, the site of the war's final and most famous battle. It was here that Major Paona Brajabasi and his fellow Manipuri soldiers made a legendary last stand against the invading British forces. Today, Khongjom Day is observed every April to honor their sacrifice.
During World War II, the broader Imphal Valley, including areas around Thoubal, saw significant troop movements and skirmishes as Allied forces defended India against the Japanese advance. Post-independence, Thoubal evolved from a collection of agrarian villages into a prominent administrative center, officially becoming a district headquarters when the Thoubal district was carved out of the erstwhile Manipur Central District in 1983.
