Kalhana work Rajatarangini is an important historical chronicle of which region?

Introduction / Context:
Rajatarangini is a famous historical work written in Sanskrit verse by Kalhana, a twelfth century Kashmiri poet historian. It is often asked about in exams because it provides an unusually continuous narrative of the kings of a specific region in early medieval India. This question checks whether you can correctly identify the region whose history is described in Rajatarangini.

Given Data / Assumptions:

• The author named is Kalhana.
• The work mentioned is Rajatarangini, which literally means river of kings.
• The options list Kashmir, the reign of Harsha, Rajasthan, and the reign of Chandragupta.

Concept / Approach:
Rajatarangini focuses on the line of kings who ruled the Kashmir valley. It weaves together legend, earlier records, and Kalhana own observations to create a chronicle of that region. It is not a biography of Harsha of Kanauj, nor is it a record of Rajasthan or the Mauryan period. Recognising the core association between Kalhana and Kashmir helps you select the correct answer.

Step by Step Solution:
Step 1: Recall that Kalhana was a historian and poet from Kashmir in the twelfth century. Step 2: Understand that Rajatarangini is a long poetic chronicle narrating the succession of rulers of Kashmir. Step 3: Recognise that while it sometimes mentions wider Indian events, its primary focus remains on Kashmir dynasties. Step 4: Note that the reign of Harsha of Kanauj and Chandragupta Maurya belongs to different texts and eras. Step 5: Therefore, among the options, Kashmir is the only accurate region linked with this work.

Verification / Alternative check:
Standard references in Indian historiography describe Rajatarangini as a unique regional chronicle for Kashmir. Many exam guides explicitly state that it is a history of Kashmir and often pair this fact with the name of its author. No credible text identifies Rajatarangini as a history of Rajasthan or as a dedicated account of Harsha or Chandragupta Maurya, which confirms that these options are distractors.

Why Other Options Are Wrong:
The reign of Harsha in North India: Information about Harsha is primarily drawn from texts like Harshacharita by Bana and the travel accounts of Xuanzang, not from Rajatarangini.
Rajasthan: While other chronicles and inscriptions deal with Rajput kingdoms, Rajatarangini is not centred on this region.
The reign of Chandragupta Maurya: Early Mauryan history relies on sources like the writings of Megasthenes and later texts, not Kalhana work.

Common Pitfalls:
Some learners mix up different Sanskrit historical works because they all deal with kings and dynasties. It is helpful to create a simple association in memory: Kalhana plus Rajatarangini equals history of Kashmir. Linking each historian with a specific region or ruler helps prevent confusion in objective questions.

Final Answer:
Kalhana Rajatarangini is a historical chronicle of Kashmir.
