Barclays traces its origins to the goldsmith banking business established in the City of London in 1690. James Barclay became a partner in the business in 1736. In 1896, several banks in London and the English provinces, including Goslings Bank, Backhouse's Bank and Gurney's Bank, united as a joint-stock bank under the name Barclays and Co.
According to a 2011 paper, Barclays was the most powerful transnational corporation in terms of ownership and thus corporate control over global financial stability and market competition, with Axa and State Street Corporation taking the 2nd and 3rd positions, respectively.
