The Indian 1000-rupee banknote is an obsolete denomination of the Indian rupee. It was first introduced by the Reserve Bank of India in 1938 under British rule and subsequently demonetized in 1946. Post-independence, the denomination was reintroduced in 1954. In January 1978, all high-denomination banknotes of ₹1000, ₹5000, and ₹10000 were demonetized in order to curb unaccounted cash money.
