Map of administrative subdivisions of Iran in 1911 –Tehran,eyalats, andvelayats
Iran has held its modern territory since theTreaty of Paris in 1857. Prior to 1937, Iran had maintained its feudal administrative divisional structure, dating back to the time the modern state was centralized by theSafavid dynasty in the 16th century, although the boundaries, roles, and rulers changed often. On the eve of thePersian Constitutional Revolution in 1905, Iran was composed ofTehran, being directly ruled by the monarch; foureyalats (Persian:ایالاتelâyât pl.,ایالتelayat sin.), ruled byQajar princes; and variousvelayats (Persian:ولایاتvelâyât pl.,ولایتvelayat sin.). Nomadic tribal confederations, such as theBakhtiari people andQashqai people, were largely independent of the domestic administrative divisions and were autonomous.
With the Constitutional Revolution, and the formation of the firstNational Consultative Assembly, Iran's administrative subdivisions were legally defined in 1907.[2] Any change in the boundaries ofeyalats,velayats, or their respective sub-districts was banned by the Iranian constitution, except with the passage of a new law by the assembly. Per the 1907 law, the following were defined:[2]
.ماده ۱ ــ مملکت محروسه ایران برای تسهیل امور سیاسی بایالات و ولایات منقسم می‌شود
ماده ۲ ــ ایالت قسمتی از مملکت است که دارای حکومت مرکزی و ولایات حاکم‌نشین جزء است و فعلاً منحصر به چهار ایالت است: آذربایجان، کرمان و بلوچستان، فارس، خراسان
ماده ۳ ــ ولایات قسمتی از مملکت است که دارای یک شهر حاکم‌نشین و توابع باشد اعم از اینکه حکومت آن تابع پایتخت یا تابع مرکز ایالتی باشد
Article 1 – Guarded Domain of Iran, for the facilitation of political affairs, will be subdivided intoEyalats andVelayats
Article 2 –Eyalat is a part of the kingdom which includes a central government and subordinate governor-ruledVelayats and at the moment there only are fourEyalat: Azerbaijan, Kerman and Baluchistan, Fars, Khurasan.
Article 3 –Velayat is a part of the kingdom which includes a governor-residence city and subordinate areas, whether its governance is subordinate to the capital [Tehran], or to the capital of anEyalat.
On 22 October 1911, the National Consultative Assembly passed another law, titled "The law of Election of National Consultative Assembly" (Persian:قانون انتخابات مجلس شورای ملی). This law presented a complete list of alleyalats andvelayats of the country, as well as their constituent districts and cities. This list presented the grouping of various towns and districts intoelectoral districts for the purpose of the election. According to this law, in 1911, Iran was made up of 27 administrative subdivisions, the region ofTehran, 4eyalats, and 22velayats.[3] Below is a list:
In 1937, Iran was reorganized to form ten numbered provinces with subordinate governorates: Gilan, Mazandaran, East Azerbaijan, West Azerbaijan, Kermanshah, Khuzestan, Pars, Kerman, Khorasan, and Isfahan.[4]
Iran has had a historical claim toBahrain as its 14th province:Bahrain province, which was under British colonial occupation until 1971. Prior to 1957, Bahrain was placed underPars province.[5] DuringSafavid Iran, Bahrain was subordinate toBushehr governorship andZubarah (located in modern-day country ofQatar) was its capital city. In 1737, underAfsharid dynasty Bahrain was made subject to Pars governorship.[6] This claim was reasserted by the new theocratic Iranian leadership after 1979 with the famous1981 coup attempt that occurred.[7]
From 1960 to 1981, the governorates were gradually raised to provincial status one by one. Since then several new provinces have been created, most recently in 2010 when the newAlborz province was split from Tehran province, and before that in 2004 when the province ofKhorasan was divided into three provinces.[8]
