In 1911 Farman Farma married his third wife, Massoumeh Khanum. In 1912 the Majlis dispatched Farman Farma as commander-in-chief of an army to repel , the third son of Mozaffar ad-Din Shah Qajar, who had laid a claim to the throne and had gathered forces in Kurdistan and Kermanshah. In this expedition Reza Khan, who would become later the Shah of Iran, served under Farman Farma's command. The expedition was eventually successful, and Farman Farma returned to Tehran in 1915. With his arrival he brought his fourth wife, Batul Khanum. The marriage, like that of his Kurdish wife, was to seal a pact.
