Tanjore district was constituted in 1799 when the Thanjavur Maratha ruler Serfoji II ceded most of his kingdom to the British East India Company in return for his restitution on the throne. Tanjore district, which is situated on the Cauvery Delta, is one of the richest rice-growing regions in South India. It was scarcely affected by famines such as the Great Famine of 1876–78.
