According to the Wiki,” The Mauryan Empire 322 B.C.E. 298 B.C.E. It was arguably the largest empire to rule the Indian subcontinent the area was 5 million km² (Southern Asia and parts of Central Asia).
The Mauryan Empire Currency was Silver Ingots (Panas).
Under Chandragupta and his successors internal and external trade, and agriculture and economic activities, all thrived and expanded across India. Chandragupta created a single and efficient system of finance, administration, and security. The Mauryan empire stands as one of the most significant periods in Indian history”.
A kshatriya clan known as the Maurya’s are referred to in the earliest Buddhist texts, Mahaparinibbana Sutta. However, any conclusions are hard to make without further historical evidence. Chandragupta first emerges in Greek accounts as “Sandrokottos”.
The Himalayan alliance gave Chandragupta a composite and powerful army made up of Yavanas (Greeks), Kambojas, Shakas (Scythians), Kiratas (Himalayans), Parasikas (Persians) and Bahlikas (Bactrians) who took Pataliputra (also called Kusumapura, “The City of Flowers”)
According to the Chanakya Kautilya’s advice, “Chandragupta also married the daughter of Seleucus, Helen to set up a policy of friendship with the Hellenistic kingdoms. This had really pushed up India’s trade with the western world”.
Now Seleucus also appointed Megasthenesas his ambassador to the Mauryan court.
According to Megasthenes, he was an ancient Greek historian, diplomat and Indian ethnographer and explorer in the Hellenistic period.
He described India in his book Indika.
Chandragupta, who live simply, honestly, and do not know writing. But he maintains a diary of his activities and decision for posterity.
Megasthanes describes the routine of Chandragupta. The king woke up before the sunrise and worshipped. His routine after bathing and breakfast was to attend to his durbar and court to dispense justice to his subjects. He received reports from his spies and sent dictates and directions to his subjects. In the noon he inspected his troops and examined the battle fitness of his men. Then in the evening, he went hunting to keep himself battle ready. One of the greatest legacies of Chandragupta was to ensure that his army was well fed and taken care. The treasury looked after all the needs of his army. Soldiers were not burdened with any thought and they were battle ready with short notice.
Chandragupta established a strong centralized state with an administration at Pataliputra which is surrounded by a wooden wall pierced by 64 gates and 570 towers”.
“The Indians all live frugally, especially when in camp. They dislike a great undisciplined multitude, and consequently, they observe good order.
During that time Mauryan India also enjoyed an era of social harmony, religious transformation, and expansion of learning and the sciences they use, Pali
Prakrit, Sanskrit languages.
Theft is of very rare occurrence. Megasthenes says that those who were in the camp of Sandrakottos, wherein lay 400,000 men, found that the thefts reported on any one day did not exceed the value of two hundred drachmae, and this among a people who have no written laws, but are ignorant of writing, and must therefore in all the business of life trust to memory.
They live, nevertheless, happily enough, being simple in their manners and frugal.
They never drink wine. Their beverage is a liquor composed from rice instead of barley, and their food is principally a rice-pottage.”
