By 400 CE, the Gupta Empire had become the dominant power in the Indian subcontinent under the reign of Chandragupta II (Vikramaditya). This period is often called the Golden Age of India, marked by political stability, economic prosperity, scientific progress, literary excellence, and flourishing art and architecture.

Gupta Empire (Brown):

The Guptas directly ruled most of northern, central, and eastern India, stretching from present-day Punjab and Uttar Pradesh to Bengal, and south into parts of the Deccan.

Kushan (Gupta Vassal):

The remnants of the once-powerful Kushan Kingdom in the northwest acknowledged Gupta supremacy. Rather than annexing the region, the Guptas allowed local rulers to govern as tributary states, securing the empire's northwestern frontier.

Western Satraps:

The Western Satraps had been defeated and annexed by Chandragupta II around 395–409 CE, bringing Gujarat, Malwa, and the western coast under Gupta influence. This victory opened important maritime trade routes and significantly increased imperial wealth.

Vakataka Dynasty:

The Vakatakas were a powerful Deccan kingdom and close allies of the Guptas through marriage. Chandragupta II's daughter, Prabhavatigupta, became queen of the Vakatakas, strengthening political and military ties between the two dynasties.

Kamapura (Gupta Vassal):

Located in the eastern Himalayan foothills, Kamapura accepted Gupta overlordship while maintaining local autonomy, helping secure the empire's northeastern frontier.

Carnatic (Gupta Vassal):

Several rulers in southern India acknowledged Gupta suzerainty or maintained diplomatic relations. Although not directly administered, these regions remained within the Gupta sphere of influence through tribute and alliances.

By 792 CE, the Tripartite Struggle had entered its middle phase, with the three great powers of early medieval India—the Gurjara-Pratiharas, Palas, and Rashtrakutas—competing for control of the prestigious city of Kannauj. Kannauj was regarded as the political heart of northern India, and possession of the city symbolized imperial supremacy. Rather than being a conflict fought in a single campaign, the struggle consisted of repeated invasions, shifting alliances, and changing fortunes among the three empires.

After earlier campaigns, the Pala ruler Dharmapala had expanded his influence into the Ganges plain. Instead of ruling Kannauj directly, he installed Chakrayudha as a vassal king, ensuring that the city remained under Pala influence while allowing a local ruler to govern. This move greatly increased Pala prestige but also threatened the ambitions of the Gurjara-Pratiharas, who considered Kannauj essential to their own claim over northern India.
