The twin cities of Kalyan and Dombivli were joined and converted into the Kalyan-Dombivli municipal corporation in 1982 to improve the administration of the twin townships. The headquarter of this city is situated in Kalyan. Kalyan and Dombivli are both cities in the Thane District of Konkan division in Maharashtra state. The city comprises a majority of Hindu residents who speak mostly in Marathi. The weather in this city follows the exact trends as that of Mumbai and is known to experience the notorious Mumbai rains. The twin city of Kalyan-Dombivli had been under the reigns of the Mughal, the Portuguese as well as the British. The celebrated Maratha heroes, held in high esteem by the residents, were the only valiant defense against these foreign invasions. The city of Kalyan used to be surrounded by a fort wall which was constructed during the Mughal age and further improved by the Maratha rulers. It was called the Durgadi Fort. History claims that a small wooden temple dedicated to Durgadevi was behind the mosque inside this fort wall. However, this historical relic was dismantled by the British and the stones were used to build the piers of Thane and Kalyan. The idol in the temple was also stolen. Only the remnants of the north-west gate of this fort still remain to remind the people of the historic past.
The State Bank of India was found on 1 July 1955. The Reserve Bank of Indias stake in SBI, took over by the government of India in 2008 to remove any conflict of interest because the RBI is the banking regulatory authority of India. The government passed the (Subsidiary Banks) Act, State Bank of India in 1959. This made SBI subsidiaries free, that had belonged to princely states before their nationalization. The operational takeover between September 1959 and October 1960, had earned eight associate state banks for SBI. The SBI united with the first Five Year Plan, which prioritized the development of rural India. The government integrated these associate banks into the State Bank of India system to expand its rural outreach. The State Bank of Jaipur and State Bank of Bikaner was merged with the State Bank of India in 1963. The SBI had 59,291 ATMs as of 31st March 2017. The SBI provided an integrated digital banking platform named "YONO" to its customers. The equity shares of SBI are listed on the Bombay Stock Exchange, and NSE.
