Title: Pataliputra
Content:  Pataliputra (IAST: ), adjacent to modern-day Patna, was a city in ancient India, originally built by Magadha ruler Ajatashatru in 490 BCE as a small fort 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 Patliputra 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 420–325 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 
Title: Names of Patna
Content:  The name Patliputra (Devanagari: पाटलिपुत्र ) is composed (sandhi) of two words, Patali and Putraka (king). The name Patliputra was given by a king of ancient Indian state of Magadh, Ajatashatru, who created a fort in Pataligrama near the River Ganges in 490 BC and later king Ajatashatru shifted his capital to Patliputra. It is also believed, the city's name Patliputra was derived from Patli, a tree variety that is found in the city.

Content:  The capital is made of unpolished buff sandstone. It is quite massive, with a length of 49 inches (1.23 meters), and a height of 33.5 inches (0.85 meters). It weighs approximately 1,800 lbs (900 kg). During the excavations it was found next to a thick ancient wall and a brick pavement. The Pataliputra capital is generally dated to the early Maurya Empire period, 3rd century BCE. This would correspond to the reign of Chandragupta, his son Bindusara or his grandson Ashoka, who are all known to have welcomed Greek ambassadors at their court (respectively Megasthenes, Deimachus and Dionysius), who may well have come to Pataliputra with presents and craftsmen as suggested by classical sources. The Indo-Greeks again possibly had a very direct presence in Pataliputra about a century later, circa 185 BCE, when they may have captured the city, although briefly, from the Sungas after the fall of the Maurya Empire.

Situated at the confluence of the Ganges, Gandhaka and Son rivers, Pataliputra formed a "water fort, or jaldurga". Its position helped it dominate the riverine trade of the Indo-Gangetic plains during Magadha's early imperial period. It was a great centre of trade and commerce and attracted merchants and intellectuals, such as the famed Chanakya, from all over India. Two important early Buddhist councils are recorded in early Buddhist texts as being held here, the First Buddhist council immediately following the death of the Buddha and the Second Buddhist council in the reign of Ashoka. Jain and Brahmanical sources identify Udayabhadra, son of Ajatashatru, as the king who first established Pataliputra as the capital of Magadha. The Sangam Tamil epic Akanaṉūṟu mentions Nanda kings ruling Pataliputra.

The Archaeological Survey of India, an Indian government agency attached to the Ministry of Culture that is responsible for archaeological research and the conservation and preservation of cultural monument in India, straightforwardly describes it as "a colossal capital in the Hellenistic style". The Pataliputra capital may reflect the influence of the Seleucid Empire or the neighboring Greco-Bactrian kingdom on early India sculptural art. In particular the city of Ai-Khanoum being

When Faxian visited the city in 400 A.D, he found the people to be rich and prosperous; they practised virtue and justice. He found that the nobles and householders of the city had constructed several hospitals in which the poor of all countries, the destitute, the crippled and the diseased can get treatment. They could receive every kind of help gratuitously. Physicians would inspect the diseases, and order them food, drink, and medicines. The city was largely in ruins when visited by Xuanzang.
