Prime Minister of Thailand Rajanubhab took over this role. In fact, the office most considered the precursor of that of the prime minister was the ancient office of "Samuha Nayok" (สมุหนายก), which was run by an "Akkhra Maha Senabodi" (อัครมหาเสนาบดี) or "chief minister in charge of civilian affairs". The first Prime Minister of Siam was Phraya Manopakorn Nititada, a judge. The title of the office was changed from "Prime Minister "of Siam"" to "Prime Minister "of Thailand"" in 1945 and then permanently with the renaming of Siam to Thailand in 1949. For most of its existence the office has been occupied by Army leaders;
Prime Minister of Afghanistan specified in the previous documents. After the collapse of Mohammad Najibullah's government, a transitional state was created. Thus, the office of Prime Minister once again played an important role in the history of the nation. There was constant friction between the President and the Premier during this period. The State had collapsed and there was not an effective central Government from 1992 until 1996. Thus, the position became "de facto" ceremonial, with little power in what was left of the Government. The title was abolished when the Taliban forces of the Islamic Emirate of Afghanistan took over control in 1996.
