英露協商
The German Empire established their Intelligence Bureau for the East on the eve of World War I, dedicated to promoting and sustaining subversive and nationalist agitations in British India and the Persian and Egyptian satellite states. The bureau was involved in intelligence and subversive missions to Persia and Afghanistan to dismantle the Anglo-Russian Entente. The bureau's operations in Persia were led by Wilhelm Wassmuss. The Germans hoped to free Persia from British and Russian influence and to further create a wedge between Russia and the British, eventually leading to an invasion of British India by locally organized armies.
