Painted Grey Ware culture in the context of "Iron Age in India"

The Bactria–Margiana Archaeological Complex (BMAC) is the modern archaeological designation for a particular Middle Bronze Age civilisation of southern Central Asia, also known as the Oxus Civilization. The civilisation's urban phase or Integration Era was dated in 2010 by Sandro Salvatori to c. 2400–1950 BC, but a different view is held by Nadezhda A. Dubova and Bertille Lyonnet, c. 2250–1700 BC.

Though it may be called the "Oxus civilization", apparently centred on the upper Amu Darya (Oxus River) in Bactria, most of the BMAC's urban sites are located in Margiana (now Turkmenistan) on the Marghab delta, and in the Kopet Dagh range. There are a few later (c. 1950–1450 BC) sites in northern Bactria, today southern Uzbekistan, but they are mostly graveyards belonging to the BMAC-related Sapalli culture. A single BMAC site, known as Dashli, lies in southern Bactria, current territory of northern Afghanistan. Sites found further east, in southwestern Tajikistan, though contemporary with the main BMAC sites in Margiana, are only graveyards, with no urban developments associated with them.

The Northern Black Polished Ware culture (abbreviated NBPW or NBP) is an urban Iron Age Indian culture of the Indian subcontinent, lasting c. 700–200 BCE (proto NBPW between 1200 and 700 BCE), succeeding the Painted Grey Ware culture and Black and red ware culture. It developed beginning around 700 BCE, in the late Vedic period, and peaked from c. 500–300 BCE, coinciding with the emergence of 16 great states or Mahajanapadas in Northern India, and the subsequent rise of the Mauryan Empire.

Recent archaeological evidences have pushed back NBPW date to 1200 BCE at Nalanda district, in Bihar, where its earliest occurrences have been recorded and carbon dated from the site of Juafardih. Similarly sites at Akra and Ter Kala Dheri from Bannu have provided carbon dating of 900-790 BCE and 1000-400 BCE, and at Ayodhya around 13th century BC or 1000 BCE.

Kosala (IPA: [koːɕɐlɐ]), sometimes referred to as Uttara Kosala (lit. 'Northern Kosala') was one of the Mahajanapadas of ancient India. It emerged as a small state during the Late Vedic period and became (along with Magadha) one of the earliest states to transition from a lineage-based society to a monarchy. By the 6th century BCE, it had consolidated into one of the four great powers of ancient northern India, along with Magadha, Vatsa, and Avanti.

Kosala belonged to the Northern Black Polished Ware culture (c. 700–300 BCE) and was culturally distinct from the Painted Grey Ware culture of the neighboring Kuru-Panchala region, following independent development toward urbanisation and the use of iron. The presence of the lineage of Ikshvaku—described as a raja in the Ṛgveda and an ancient hero in the Atharvaveda—to which Rama, Mahavira, and the Buddha are all thought to have belonged—characterized the Kosalan realm.

The Bactria–Margiana Archaeological Complex (BMAC) is the modern archaeological designation for a particular Middle Bronze Age civilisation of southern Central Asia, also known as the Oxus Civilization. The civilisation's urban phase or Integration Era was dated in 2010 by Sandro Salvatori to c. 2400–1950 BC, but a different view is held by Nadezhda A. Dubova and Bertille Lyonnet, c. 2250–1700 BC.Although commonly referred to as the “Oxus civilization” and formally designated as the “Bactria–Margiana Archaeological Complex” (BMAC), recent studies have questioned the geographic adequacy of these terms. While the traditional labels emphasize the concentration of major urban sites in Margiana and northern Bactria, new archaeological surveys and excavations show that the cultural core of this Bronze Age complex was considerably broader. Significant sites have been documented across northeastern Iran, within the historical region of Greater Khorasan, including newly excavated settlements such as Tepe Chalow, Kalat-e Yavar, and Shahrak-e Firouzeh, along with numerous surveyed locations exhibiting characteristic BMAC material culture.On the basis of this wider distribution—extending from Sabzevar and Nishapur to the Murghab delta and Tajikistan—some scholars (e.g., Biscione & Vahdati) argue that “BMAC” and “Oxus Civilization” are overly restrictive, either overlooking formative areas or limiting the phenomenon to Bactria and Margiana.". Because the full spread of sites corresponds closely to the historical expanse of Greater Khorasan and reflects long-term cultural continuity into the Iron Age and later periods, these authors propose the broader term “Greater Khorasan Civilization” (GKC) for this archaeological complex.

There are a few later (c. 1950–1450 BC) sites in northern Bactria, today southern Uzbekistan, but they are mostly graveyards belonging to the BMAC-related Sapalli culture. A single BMAC site, known as Dashli, lies in southern Bactria, current territory of northern Afghanistan. Sites found further east, in southwestern Tajikistan, though contemporary with the main BMAC sites in Margiana, are only graveyards, with no urban developments associated with them.

The Cemetery H culture was a Bronze Age culture in the Punjab region in the northern part of the Indian subcontinent, from about 1900 BCE until about 1300 BCE. It is regarded as a regional form of the late phase of the Harappan (Indus Valley) civilisation (alongside the Jhukar culture of Sindh and Rangpur culture of Gujarat), but also as a phase of the Indo-Aryan migrations.

Black and red ware (BRW) is a South Asian earthenware, associated with the Neolithic phase, Harappa, Bronze Age India, Iron Age India, the Megalithic and the early historical period. Although it is sometimes called an archaeological culture, the spread in space and time and the differences in style and make are such that the ware must have been made by several cultures.

In the Western Ganges plain (western Uttar Pradesh) it is dated to c. 1450–1200 BCE, and is succeeded by the Painted Grey Ware culture; whereas in the Central and Eastern Ganges plain (eastern Uttar Pradesh, Bihar, and Bengal) and Central India (Madhya Pradesh) the BRW appears during the same period but continues for longer, until c. 700–500 BCE, when it is succeeded by the Northern Black Polished Ware culture.
