Final answer:
Marji discovers that Reza overthrew the emperor of the Qajar Dynasty, contributing to Iran's historical internal strife and foreign interference. This pattern recurred with the CIA and MI-6 orchestrated coup against Prime Minister Mohammad Mossadeq.
Step-by-step explanation:
Marji learns that the emperor overthrown by Reza was the last emperor of the Qajar Dynasty, which ruled Iran from 1785 to 1925. This revelation adds to the conflict by highlighting the historical pattern of foreign intervention and internal power struggles affecting Iran's sovereignty and political stability.
Such patterns continued even after Reza's rule, when the democratic Prime Minister Mohammad Mossadeq, who attempted to nationalize Iran's oil fields, was overthrown through a CIA and MI-6 operation, leading to the reinstatement of the Shah, a ruler more amenable to foreign oil interests.
