In 1907, the Rothschilds subsidized and then established control over many oil companies through the Russian-Asian Bank: the Absheron Oil Company, having seized 40 per cent of its shares; Shikhovo; Melikov; the Russian Oil Society etc.
In 1910-1911, Edmund Rothschild acquired the majority of the shares in the Russian companies Neft (Oil) and G. M. Lianozov & Sons for approximately two million roubles. The shares of these companies were highly quoted on the Paris stock exchange. As a result, before the 1917 October Revolution, the Rothschilds owned over 35 per cent of the total share capital of 15 large enterprises of the Russian oil industry.
The nationalization of the Caspian-Black Sea Company and the Mazut association by a decree of the Baku Commune dated 2 June 1918 had no direct bearing on the Rothschilds because they had sold their Russian oil companies to the Anglo-Dutch Trust Royal Dutch Shell (the main rival of the American syndicate Standard Oil) in 1912, receiving in return 27.5 million roubles, as well as 20 per cent of the shares of the Shell trust in Paris. Already by 1913 British entrepreneurs had begun to take the lead in Russia’s oil business.
