Using U.S. State Department archives, Persian sources, and memoirs of British military officers, Majd provides an outline of military, diplomatic, and political events in Persia during 1914-1918. Persia in World War I and Its Conquest by Great Britain describes Persia's failure to gain recourse at Versailles, alleging that Persia was a loser both in war and peace. It is the second book in Majd's World War I triology.

"Mohammad Majd has...diligently mined a much under-utilized source, the U.S. State Department archives, and assembled a great deal of useful and interesting information. The analysis he presents, furthermore, particularly regarding the political context in Iran immediately prior to the outbreak of the war, offers some valuable insights." - Iranian Studies
