Ilam province in the context of "Ancient Persia"

The History of Iran (also known as Persia) is intertwined with Greater Iran, which is a region encompassing all of the areas that have witnessed significant settlement or influence by the Iranian peoples and the Iranian languages – chiefly the Persians and the Persian language. Central to this region is the Iranian plateau, now largely covered by modern Iran. The most pronounced impact of Iranian history can be seen stretching from Anatolia in the west to the Indus Valley in the east, including the Levant, Mesopotamia, the Caucasus, and parts of Central Asia. It also overlaps or mingles with the histories of many other major civilizations, such as India, China, Greece, Rome, and Egypt.

Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to the 5th millennium BC. The Iranian plateau's western regions integrated into the rest of the ancient Near East with the Elamites (in Ilam and Khuzestan), the Kassites (in Kuhdesht), the Gutians (in Luristan), and later with other peoples like the Urartians (in Oshnavieh and Sardasht) near Lake Urmia and the Mannaeans (in Piranshahr, Saqqez and Bukan) in Kurdistan. German philosopher Georg Wilhelm Friedrich Hegel called the Persians the "first Historical People" in his Lectures on the Philosophy of World History. The sustained Iranian empire is understood to have begun with the rise of the Medes during the Iron Age, when Iran was unified as a nation under the Median kingdom in the 7th century BC. By 550 BC, the Medes were sidelined by the conquests of Cyrus the Great, who brought the Persians to power with the establishment of the Achaemenid Empire. Cyrus' ensuing campaigns enabled the Persian realm's expansion across most of West Asia and much of Central Asia, and his successors would eventually conquer parts of Southeast Europe and North Africa to preside over the largest empire the world had yet seen. In the 4th century BC, the Achaemenid Empire was conquered by the Macedonian Empire of Alexander the Great, whose death led to the establishment of the Seleucid Empire over the bulk of former Achaemenid territory. In the following century, Greek rule of the Iranian plateau came to an end with the rise of the Parthian Empire, which also conquered large parts of the Seleucids' Anatolian, Mesopotamian, and Central Asian holdings. While the Parthians were succeeded by the Sasanian Empire in the 2nd century, Iran remained a leading power for the next millennium, although the majority of this period was marked by the Roman–Persian Wars.

Iranian Kurdistan and Eastern Kurdistan (Kurdish: ڕۆژھەڵاتی کوردستان, romanized: Rojhilatê Kurdistanê) are unofficial names for the parts of northwestern Iran with either a majority or sizable population of Kurds. Geographically, it includes the West Azerbaijan province, Kurdistan province, Kermanshah province, Ilam province and parts of Hamadan province and Lorestan province.

In totality, Kurds are about 10% of Iran's total population and nearly all of them are bilingual in their ethnic language and Persian. According to the last census conducted in 2006, the four main Kurdish-inhabited provinces in Iran – West Azerbaijan, Kermanshah province, Kurdistan province and Ilam province – had a total population of 6,730,000. Kurds generally consider northwestern Iran (Eastern Kurdistan) to be one of the four parts of a Greater Kurdistan, which under that conception are joined by parts of southeastern Turkey (Northern Kurdistan), northern Syria (Western Kurdistan), and northern Iraq (Southern Kurdistan).

The Lurs, Lors or Luris (Persian: لر) are an Iranian people living in western and southern Iran. The four Luri branches are the Bakhtiari, Mamasani, Kohgiluyeh and Lur proper, who are principally linked by the Luri language.

Lorestan province is named after the Lurs, but not all Lurs live in Lorestan, nor are all the inhabitants of Lorestan ethnic Lurs. Many Lurs live in other provinces of Iran including Fars, Chaharmahal and Bakhtiari, Kohgiluyeh and Boyer-Ahmad, Khuzestan, Hamadan, Isfahan, Tehran southern Ilam province, and Genaveh county in Bushehr province.

Luri (Northern Luri: لری, Southern Luri: لری) is a Southwestern Iranian language continuum spoken by the Lurs, an Iranian people native to West Asia. The Luri dialects are descended from Middle Persian and are Central Luri, Bakhtiari, and Southern Luri. This language is spoken mainly by the Bakhtiari and the Northern and Southern Lurs (Lorestan, Ilam, Kohgiluyeh and Boyer-Ahmad, Mamasani, Sepidan, Bandar Ganaveh, Bandar Deylam) in Iran.
