TAQIZADEH (Taqizāda), SAYYED ḤASAN (b. Tabriz, 30 Ramażān 1295/27 September 1878; d. Tehran, 8 Bahman 1348/28 January 1970), distinguished statesman, constitutionalist, and scholar.
(Persian: سیدحسن تقیزاده)
He was an influential Iranian politician and diplomat, of Azeri origin, during the Qajar dynasty under the reign of Mohammad Ali Shah, as well as the Pahlavi dynasty under the reign of Reza Shah and Mohammad Reza Shah. Although in the modern political history Taqizadeh is known as a secular politician, who believed that "outwardly and inwardly, in body and in spirit, Iran must become Europeanized", he came from a traditional Islamic Sayyed-family (descendant of Muhammad). His father, Sayyed Taqi, was a clergyman and when Sayyed Hasan became a mullah, it seemed likely that he would follow in his father's footsteps. From an early age Taqizadeh showed interest in enlightened ideas and the Western concept of constitutionalism. This interest can be traced back to the socio-political sphere in which Taqizadeh became an adult. He grew up in Tabriz, the capital city of East Azerbaijan province, which was the gateway to the modern and progressive ideas coming from Russia and especially Western Europe. In the time of World War I, World War II and after, Taqizadeh was the most influential person in Iran who support intress of German Empire against Russia and Britain.
