Both the Triple Alliance and the Triple Entente engaged in the negotiation of secret treaties throughout the duration of the war. The majority of these were revealed only after the Russian Revolution when the new Soviet Republic was keen to expose both the duplicity of the Tsarist regime and the nature of the Imperialist Powers. Perhaps the most revealing of the Secret Treaties was the one negotiated between Britain and France, otherwise known as the Sykes Picot agreement. As the map shows this agreement divided the Middle East between the two powers.
