During the reign of the most powerful Meitei King Pamheiba a.k.a. Garib Nawaz (1709–1748) for the first time, the heartland area of the Tangkhul country was invaded and brought under the suzerainty of Manipur. In 1716, the king’s forces invaded the great Tangkhul village of Hundung and sixty eight prisoners were captured. In 1733, the king sent a military expedition to Ukhrul and conquered. The outcome of the expeditions incurred heavy casualty on the King’s forces; the royal chronicles record the death of seventy Meitei soldiers. The defeat of these two big villages situated in the heart of Tangkhul country was landmark in the establishment of the Meitei political hegemony over the Tangkhul hills which started feeling the brunt of the Meitei power. The Ningek inscription of king Garib Nawaz refers to the Khullakpa of Okhrul (Ukhrul). Ukhrul was the headquarters of the Tangkhul Long (Tangkhul Assembly), as well as the Tangkhul annual fair locally known as "Leh Khangapha" used to be held at Somsai in Ukhrul. Hence the fall of Ukhrul in 1733 in the hands of the Meitei Maharaja herald the fall of the Tangkhuls country.
