Answer:
After the Mauryan Empire fell, no one major power held control over a substantial part of India for five hundred years. Rather, from c. 200 BCE to 300 CE, India saw a fairly rapid turnover of numerous, regional kingdoms. Some of these were located in northern India, along the Ganges River, but others grew up in the south—the Indian Peninsula—for the first time. Also, some kingdoms emerged through foreign conquest. Outsiders in Central Asia and the Middle East saw India as a place of much wealth, and sought to plunder or rule it. Thus, throughout its history, India was repeatedly invaded by conquerors coming through mountain passes in the northwest. Many of these, like King Kanishka of the Kushan Empire (c. 100 CE), established notable kingdoms that extended from India into these neighboring regions from which they came.
Even after 300 CE and up to the fifteenth century, India was never again unified for any length of time by one large empire. For that reason, historians highlight those kingdoms that became substantial regional powers and contributed in other important ways to India’s civilization. The period 300 – 600 CE, for instance, is often referred to as the Gupta Period and Classical Age. The Guptas (c. 320 – 550) were rulers who forged an impressive empire in northern India. As their empire flourished, Indian intellectuals were also setting standards for excellence in the fields of art, architecture, literature, and science, in part because of Gupta patronage. But important kingdoms also developed in south India.
The last period covered in this chapter is early medieval India (c. 600 – 1300 CE). After the Gupta Empire, and during the following seven centuries, the pattern of fragmentation intensified, as numerous regional kingdoms large and small frequently turned over. Confronting such an unstable and fluid political scene, medieval kings granted land to loyal subordinate rulers and high officers of their courts. The resulting political and economic pattern is referred to as Indian feudalism. Also, kings put their greatness on display by waging war and building magnificent Hindu temples in their capital cities. And, during the medieval period, a new political and religious force entered the Indian scene, when Muslim Arab and Turkic traders and conquerors arrived on the subcontinent.
This overview briefly summarizes major periods in India’s political history. But the history of a civilization consists of more than just rulers and states, which is why historians also pay close attention to social, cultural, and economic life every step of the way. This attention is especially important for India. Although the Asian subcontinent sees a long succession of kingdoms and empires and was usually divided up by several at any particular point in its history, peoples over time came to share some things in common. Socially, the peoples of India were largely organized by the caste system. Culturally, the peoples of India shared in the development of Hinduism and Buddhism, two major religious traditions that shaped people’s understanding of the world and their place in it. Finally, throughout the ancient and medieval periods, India flourished as a civilization because of its dynamic economy. The peoples of India shared in that too, and that meant they were linked in networks of trade and exchange not only with other parts of South Asia but also with neighboring regions of the Afro-Eurasian world.
