query: Was Iran part of the Persian empire?
passage: History of Iran
Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 7000 BC.[1] The southwestern and western part of the Iranian Plateau participated in the traditional Ancient Near East with Elam, from the Early Bronze Age, and later with various other peoples, such as the Kassites, Mannaeans, and Gutians. Georg Wilhelm Friedrich Hegel calls the Persians the "first Historical People".[2] The Medes unified Iran as a nation and empire in 625 BC.[3] The Achaemenid Empire (550–330 BC), founded by Cyrus the Great, was the first Persian empire and it ruled from the Balkans to North Africa and also Central Asia, spanning three continents, from their seat of power in Persis (Persepolis). It was the largest empire yet seen and the first world empire.[4] The First Persian Empire was the only civilization in all of history to connect over 40% of the global population, accounting for approximately 49.4 million of the world's 112.4 million people in around 480 BC.[5] They were succeeded by the Seleucid, Parthian, and Sasanian Empires, who successively governed Iran for almost 1,000 years and made Iran once again as a leading power in the world. Persia's arch-rival was the Roman Empire and its successor, the Byzantine Empire.
passage: Ethnic minorities in Iran
Iran (then called Persia) traditionally was governed over the last few centuries in a fairly decentralised way with much regional and local autonomy. In particular, weaker members of the Qajar dynasty often did not rule much beyond the capital Tehran, a fact exploited by the imperial powers Britain and Russia in the 19th century. For example, when British cartographers, diplomats, and telegraph workers traveled along Iran's southern coast in the early 19th century laden with guns and accompanied by powerful ships, some local chieftains quickly calculated that their sworn allegiance to the Shah in Tehran with its accompanying tax burden might be optional. When queried, they proclaimed their own local authority. However during Constitutional Revolution ethnic minorities including Azeris, Bakhtiaris and Armenians fought together for establishment of democracy in Iran while they had the power to become independent.
