[3] The bank was established in 1908 to "carry out the business of banker and bill discounter, and of Dealer in Stocks, Shares, Bonds, Debentures and other Securities to assist in the development of Irish industries".
[11] Several times in 1919 and 1920, during the Irish War of Independence, the Dublin Metropolitan Police (DMP) raided and ordered the closure of 6 Harcourt Street.
[17][18][19] The inquiry was led by Alan Bell, a resident magistrate, as part of his broader, mostly secret, search for Dáil funds.
[27] In the Second Dáil on 18 August 1921, Séamus Dwyer claimed "All the monies invested [in the Sinn Féin Bank] were in jeopardy".
[28] On 19 October 1921, the bank passed a resolution to wind up the company and appointing William O'Brien Hishon liquidator.
[14] The confiscated books were returned to Hishon "in a sack" after the June 1921 truce ended the Anglo-Irish War, and he set about deciphering them.
On 16 April 1923, the Free State Chancery Division ordered the winding up of the Sinn Féin Bank company, appointing Donal O'Connor as liquidator.
[32] In April 1926, Dublin County Council, presented with a demand for £113 for damage caused by the DMP raids in 1919–21, voted 13–1 not to pay.
[34] The republican Dáil had deposited money with the bank and the Irish Free State, as its legal successor, received £1,198 10s.
