The Second Mysore War came to an end with the 1784 Treaty of Mangalore. It was the last occasion when an Indian king dictated terms to the British, and the treaty is a prestigious document in the history of India. The war is also remembered for alleged excesses committed by Hyder Ali and Tipu Sultan in Tanjore. During the period of occupation which lasted six months, Hyder Ali and Tipu Sultan are believed to have impoverished the country, destroying crops and cattle. As late as 1785, the Dutch missionary Christian Friedrich Schwarz describes Tipu's alleged abduction of 12,000 children from the region. The economic output of Tanjore is estimated to have fallen by 90% between 1780 and 1782. The ravages of Hyder and Tipu were followed by alleged expeditions of plunder launched by the Kallars. The economic devastation wrought by these attacks was so severe that Tanjore's economy did not recover until the start of the 19th century; the era is referred to in local folklore as the Hyderakalam.
