Janapada in the context of "History of Punjab"

Anatomically modern humans first arrived on the Indian subcontinent between 73,000 and 55,000 years ago. The earliest known human remains in South Asia date to 30,000 years ago. Sedentariness began in South Asia around 7000 BCE; by 4500 BCE, settled life had spread, and gradually evolved into the Indus Valley Civilisation, one of three early cradles of civilisation in the Old World, which flourished between 2500 BCE and 1900 BCE in present-day Pakistan and north-western India. Early in the second millennium BCE, persistent drought caused the population of the Indus Valley to scatter from large urban centres to villages. Indo-Aryan tribes moved into the Punjab from Central Asia in several waves of migration. The Vedic Period of the Vedic people in northern India (1500–500 BCE) was marked by the composition of their extensive collections of hymns (Vedas). The social structure was loosely stratified via the varna system, incorporated into the highly evolved present-day Jāti system. The pastoral and nomadic Indo-Aryans spread from the Punjab into the Gangetic plain. Around 600 BCE a second urbanization occured resulting in a new interregional culture; then, smaller janapadas (realms) were consolidated into mahajanapadas (great states). This period saw the rise of new ascetic movements and religious concepts, including the rise of Jainism and Buddhism. The latter was synthesized with the preexisting religious cultures of the subcontinent, giving rise to Hinduism.

Chandragupta Maurya overthrew the Nanda Empire and established the first great empire in ancient India, the Maurya Empire. India's Mauryan king Ashoka is widely recognised for the violent Kalinga War and his historical acceptance of Buddhism and his attempts to spread nonviolence and peace across his empire. This period marks the rapid dissemination of Śramaṇic religions.

In the prehistory of the Indian subcontinent, the Iron Age succeeded Bronze Age India and partly corresponds with the megalithic cultures of South India. Other Iron Age archaeological cultures of north India were the Painted Grey Ware culture (1300–300 BCE) and the Northern Black Polished Ware (700–200 BCE). This corresponds to the transition of the Janapadas or principalities of the Vedic period to the sixteen Mahajanapadas or region-states of the early historic period, culminating in the emergence of the Maurya Empire towards the end of the period.

The earliest evidence of iron smelting predates the emergence of the Iron Age proper by several centuries.

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.
