Mahapadma Nanda
Explanation
The Nanda dynasty, which succeeded the Shishunaga dynasty, represents the zenith of the Magadhan Empire's expansion before the Mauryas. Mahapadma Nanda, the founder of the dynasty, is historically recognized as the first empire builder of India, transforming Magadha into a trans-regional power.
Detailed Analysis:
- Mahapadma Nanda (Correct): He is described in the Puranas as "Sarvakshatrantaka" (destroyer of all Kshatriyas) and "Ekarat" (sole sovereign). He defeated several contemporary dynasties, including the Kurus, Panchalas, Kasis, Haihayas, Kalingas, Asmakas, Maithilas, and Surasenas. By conquering the Kuru and Surasena territories, he extended the Magadhan control up to the fringes of the north-western part of the Indian subcontinent (modern-day Punjab/Haryana region). Greek accounts later mention that the Nanda army's presence at the Beas river deterred Alexander's further advance.
- Bimbisara and Ajatasattu (Incorrect): These rulers belonged to the Haryanka dynasty. While they significantly strengthened Magadha through the annexation of Anga, Kosala, and the Vajji confederacy, their expansion was primarily concentrated in Eastern and Central India (modern-day Bihar and Eastern Uttar Pradesh). They did not extend control to the North-West.
- Porus (Incorrect): Porus (Puru) was the ruler of the Paurava kingdom located between the Jhelum and Chenab rivers in the North-West. He was a contemporary of Alexander and fought the Battle of Hydaspes. He was a local ruler of the Punjab region, not a ruler of the Nanda dynasty or the Magadhan Empire.
Key Takeaway:
Mahapadma Nanda is credited with establishing the first great empire of North India, extending Magadhan supremacy from Kalinga in the east to the borders of the Punjab in the north-west.
