First Buddhist Council was held soon after the mahaparinirvana of the Buddha, around 400 BC under the patronage of king Ajatshatru with the monk Mahakasyapa presiding, at Rajgriha, in the Sattapani Cave.

The Fourth (not first) Buddhist Council was held at Kundalvana, Kashmir where the council distinctly divided the Buddhism into 2 sects Mahayana and Hinayana.

Megasthenes gives a detailed description of the personal life of Chandragupta Maurya. He led a very splendid life and his palace was unique in its beauty. He also writes that the king was an autocrat and he was the master of un-limited powers. He kept himself fully aware of the main events of his empire through his spies. During Chandragupta reign, the state regulated trade, levied taxes, and standardized weights and measures.
Trade and commerce also flourished during this time. The state was responsible for providing irrigational facilities, succor, sanitation, and famine relief to its masses. Megasthenes, in his writings, has praised the efficient Mauryan administration.

One means of claiming high status was to identify with a variety of deities. This strategy is best exemplified by the Kushanas (c. first century BCE-first century CE), who ruled over a vast kingdom extending from Central Asia to northwest India.
Colossal statues of Kushana rulers have been found installed in a shrine at Mat near Mathura (Uttar Pradesh).

Similar statues have been found in a shrine in Afghanistan as well. Some historians feel this indicates that the Kushanas considered themselves godlike. Many Kushana rulers also adopted the title devaputra, or “son of god”, possibly inspired by Chinese rulers who called themselves sons of heaven. The Vijayanagara kings claimed to rule on behalf of the god Virupaksha. Rulers also indicated their close links with the gods by using the title “Hindu Suratrana” this meant Hindu Sultan.
