Megasthenes in the context of "Maurya"

The Maurya Empire was a geographically extensive Iron Age historical power in South Asia with its power base in Magadha. Founded by Chandragupta Maurya around c. 320 BCE, it existed in loose-knit fashion until 185 BCE. The primary sources for the written records of the Mauryan times are partial records of the lost history of Megasthenes in Roman texts of several centuries later; and the Edicts of Ashoka. Archaeologically, the period of Mauryan rule in South Asia falls into the era of Northern Black Polished Ware (NBPW).

Through military conquests and diplomatic treaties, Chandragupta Maurya defeated the Nanda dynasty and extended his suzerainty as far westward as Afghanistan below the Hindu Kush and as far south as the northern Deccan; however, beyond the core Magadha area, the prevailing levels of technology and infrastructure limited how deeply his rule could penetrate society. During the rule of Chandragupta's grandson, Ashoka (ca. 268–232 BCE), the empire briefly controlled the major urban hubs and arteries of the subcontinent excepting the deep south. The Mauryan capital (what is today Patna) was located in Magadha; the other core regions were Taxila in the northwest; Ujjain in the Malwa Plateau; Kalinga on the Bay of Bengal coast; and the precious metal-rich lower Deccan Plateau. Outside the core regions, the empire's geographical extent was dependent on the loyalty of military commanders who controlled the armed cities scattered within it.

Madurai is a major city in the Indian state of Tamil Nadu. It is the cultural capital of Tamil Nadu and the administrative headquarters of Madurai district, which is governed by the Madurai Municipal Corporation established on 1 November 1866. As of the 2011 census, it is the third largest metropolis in Tamil Nadu after Chennai and Coimbatore in terms of population and 27th largest urban agglomeration in India. Located on the banks of Vaigai River, Madurai has been a major settlement for two millennia and has a documented history of more than 2500 years. It is often referred to as "Thoongatha Nagaram", meaning "the city that never sleeps".

Madurai is one of the oldest cities in India and South Asia. The third Tamil Sangam, a major congregation of Tamil scholars, is said to have been held in the city. The recorded history of the city goes back to the 3rd century BCE, being mentioned by Megasthenes, the Greek ambassador to the Mauryan Empire, and Kautilya, a minister of the Mauryan emperor Chandragupta Maurya. Signs of human settlements and Roman trade links dating back to 300 BCE are evident from excavations by Archeological Survey of India in Manalur. The city is believed to be of significant antiquity and has been ruled, at different times, by the Pandyan Kingdom, Chola Empire, Madurai Sultanate, Vijayanagar Empire, Madurai Nayaks, Carnatic kingdom, and the British East India Company's British Raj. The city has a number of historical monuments, with the Koodal Azhagar temple, Meenakshi Temple and the Thirumalai Nayakkar Mahal being the most prominent.

Pataliputra (IAST: Pāṭaliputra), adjacent to modern-day Patna, Bihar, was a city in ancient India, originally built by Magadha ruler Ajatashatru in 490 BCE, as a small fort (Pāṭaligrāma) near the Ganges river. Udayin laid the foundation of the city of Pataliputra at the confluence of two rivers, the Son and the Ganges. He shifted his capital from Rajgriha to Pataliputra due to the latter's central location in the empire.

It became the capital of major powers in ancient India, such as the Shishunaga Empire (c. 413–345 BCE), Nanda Empire (c. 460 or 420 – c. 325 BCE), the Maurya Empire (c. 320–180 BCE), the Gupta Empire (c. 320–550 CE), and the Pala Empire (c. 750–1200 CE). During the Maurya period (see below), it became one of the largest cities in the world. As per the Greek diplomat, traveler and historian Megasthenes, during the Mauryan Empire (c. 320–180 BCE) it was among the first cities in the world to have a highly efficient form of local self government.The location of the site was first identified in modern times in 1892 by Laurence Waddell, published as Discovery of the Exact Site of Asoka's Classic Capital. Extensive archaeological excavations have been made in the vicinity of modern Patna. Excavations early in the 20th century around Patna revealed clear evidence of large fortification walls, including reinforcing wooden trusses.
