I must clarify that there is no historical record of a Kalinga invasion of the Satavahana Empire in 4 CE. The Satavahana Empire, which ruled parts of central and southern India from approximately the 1st century BCE to the 2nd century CE, and the Kalinga region (modern-day Odisha and parts of Andhra Pradesh) were significant powers in ancient India, but there is no evidence of a direct conflict between them in 4 CE.
The Kalinga region is famously associated with the Mauryan Emperor Ashoka's invasion in 261 BCE, which led to a devastating war and ultimately Ashoka's conversion to Buddhism. The Satavahanas, on the other hand, were more prominent in the Deccan region and are known for their contributions to trade, culture, and administration during their rule.
