History of SBI:- The roots of the State Bank of India lie in the first decade of the 19th century, when the Bank of Calcutta, later renamed the Bank of Bengal, was established on 2 June 1806. The Bank of Bengal was one of three Presidency banks, the other two being the Bank of Bombay (incorporated on 15 April 1840) and the Bank of Madras (incorporated on 1 July 1843). All three Presidency banks were incorporated as joint and were the result of royal charters. These three banks received the exclusive right to issue paper currency till 1861 when, with the Paper Currency Act, the right was taken over by the Government of India. The Presidency banks amalgamated on 27 January 1921, and the re-organized banking entity took as its name Imperial Bank of India. The Imperial Bank of India remained a joint stock company but without Government participation. Seal of Imperial Bank of India 4.

On 1 July 1955, the Imperial Bank of India became the State Bank of India. In 2008, the government of India acquired the Reserve Bank of Indias stake in SBI so as to remove any conflict of interest because the RBI is the countrys banking regulatory authority. In 1959, the government passed the State Bank of India (Subsidiary Banks) Act, which made eight state banks associates of SBI. A process of consolidation began on 13 September 2008, when the State Bank of Saurashtra merged with SBI. SBI has acquired local banks in rescues. The first was the Bank of Behar (est. 1911), which SBI acquired in 1969, together with its 28 branches. The next year SBI acquired National Bank of Lahore (est. 1942), which had 24 branches. Five years later, in 1975, SBI acquired Krishnaram Baldeo Bank, which had been established in 1916 in Gwalior State, under the patronage of Maharaja Madho Rao Scindia. The bank had been the Dukan Pichadi, a small moneylender, owned by the Maharaja. The new banks first manager was Jall N. Broacha, a Parsi. In 1985, SBI acquired the Bank of Cochin in Kerala.
