The term Indo-Iranian is short for Indic and Iranian. It refers to speakers of the Indo-Iranian languages, i.e., Indo-Aryans, Iranians and the speakers of the Nuristani languages. The historic term for these cultures is Aryan.
Their history becomes sensational with their invention of the horse-drawn chariot.
Asko Parpola and other scholars have proposed a two wave (or multiple wave) model for the migration of Indo-Iranians and Indo-Aryans.
Based on linguistic evidence scholars argue that the Indo-Iranians were the first to exploit the chariot, leading what is sometimes called the first wave of Indo-Iranian expansion. It is assumed that this expansion went into the Caucasus, the Iranian plateau, Afganistan, and, most significantly, India. They also expanded into Mesopotamia and Syria, and introduced the horse and chariot culture to this part of the world.
They left linguistic remains in a Hittite discourse on horse-training written by one "Kikkuli the Mitanni". Other evidence is found in references to the names of Mitanni rulers and the gods they swore by in treaties; these remains are found in the archives of the Mitanni's neighbors. The time period for this is about 1440-1330 BCE.
The standard model for the entry of the Indo-European languages into India is that this first wave went over the Hindu Kush, either into the headwaters of the Indus or the Ganges (and probably, both). The earliest stratum of Vedic Sanskrit, preserved only in the Rigveda, is assigned to roughly 1700-1400 BCE. From the Indus, the Indo-Aryan languages spread with the migrants, who from (c1500 BCE-c500BCE), were able to spread over the northeren and central parts of the subcontinent, sparing the extreme south. The Aryans in these areas established several powereful kingdoms and principalities in the region, from eastern Afghanistan to the doorstep of Bengal. The most powerful of these kingdoms was Magadha, which lasted until the 4th century BCE, when it was conquered by Chandragupta Maurya and annexed into the Mauryan empire.
In eastern Afghanistan and western Pakistan, whatever Indo-Aryan dialects that were spoken there were eventually pushed out by the Iranian languages. Most Indo-Aryan languages, however, were and still are prominent in the Indian subcontinent. Today, Indo-Aryan languages are spoken in India, Pakistan, Bangladesh, Nepal, Sri Lanka and the Maldives.
In Central Asia, the Turkic languages and culture have replaced Iranian, but a substantial minority remains in Uzbekistan and Turkmenistan. The Iranian languages are now confined to Iran, Kurdistan, Afganistan, western Pakistan, Tajikistan, Turkey and the Caucasus.

Parpola (1999) suggests the following identifications:
| date range | archaeological culture | identification suggested by Parpola |
|---|---|---|
| 2800-2000 BCE | late Catacomb and Poltavka cultures | late PIE to Proto-Indo-Iranian |
| 2000-1800 BCE | Srubna and Abashevo cultures | Proto-Iranian |
| 2000-1800 BCE | Petrovka-Sintashta | Proto-Indo-Aryan |
| 1900-1700 BCE | BMAC | "Proto-Dasa" Indo-Aryans establishing themselves in the existing BMAC settlements, defeated by "Proto-Rigvedic" Indo-Aryans around 1700 |
| 1900-1400 BCE | Cemetary H | Indian Dasa |
| 1800-1000 BCE | Alakul-Fedorovo | Indo-Aryan, including "Proto-Sauma-Aryan" practicing the Soma cult |
| 1700-1400 BCE | early Swat culture | Proto-Rigvedic = Proto-Dardic |
| 1700-1500 BCE | late BMAC | "Proto-Sauma-Dasa", assimilation of Proto-Dasa and Proto-Sauma-Aryan |
| 1500-1000 BCE | Early West Iranian Grey Ware | Mitanni-Aryan (offshoot of "Proto-Sauma-Dasa") |
| 1400-800 BCE | late Swat culture and Punjab, Painted Grey Ware | late Rigvedic |
| 1400-1100 BCE | Yaz II-III, Seistan | Proto-Avestan |
| 1100-1000 BCE | Gurgan Buff Ware, Late West Iranian Buff Ware | Proto-Persian, Proto-Median |
| 1000-400 BCE | Iron Age cultures of Xinjang | Proto-Saka |
The Indo-European language spoken by the Indo-Iranians in the late 3rd millennium BC was a Satem language still not removed very far from the Proto-Indo-European language, and in turn only removed by a few centuries from the Vedic Sanskrit of the Rigveda. The main phonological change separating Proto-Indo-Iranian from Proto-Indo-European is the collapse of the ablauting vowels *e, *o, *a into a single vowel, Proto-Indo-Iranian *a (but see Brugmann's law). Grassmann's law and Bartholomae's law were also complete in Proto-Indo-Iranian.
Among the sound changes from Proto-Indo-Iranian to Indo-Aryan is the loss of the voiced sibilant *z, among those to Iranian is the de-aspiration of the PIE voiced aspirates.
