Explanations:The question pertains to the historical renaming of regions in India, specifically focusing on the ancient kingdom of Kalinga. Kalinga was an ancient kingdom located in the eastern part of India, corresponding to the modern-day region of Coastal Orissa. The name Kalinga is significant in Indian history, particularly due to the Kalinga War, which took place in the 3rd century BCE.
The Kalinga War was fought between the Mauryan Empire, led by Emperor Ashoka, and the kingdom of Kalinga. This war was one of the most brutal in ancient Indian history, resulting in a large number of casualties and destruction. The aftermath of the war had a profound impact on Emperor Ashoka, leading to his conversion to Buddhism and his subsequent adoption of non-violent principles.
Over time, the region that was once known as Kalinga has undergone several changes in its name and administrative divisions. Today, the region is part of the state of Odisha, and the coastal part of this state is often referred to as Coastal Orissa. This historical context is crucial for understanding the evolution of the region's identity and its significance in Indian history.
It is important to note that the name Kalinga is not associated with other regions such as Punjab or Jammu and Kashmir. These regions have their own historical and cultural contexts that are distinct from the history of Kalinga. Therefore, the correct answer to the question is that Coastal Orissa had its old name as Kalinga.
