Rashtrakutas adopted Garuda as a dynastic emblem after the imperial Gupta. Silver coins of the Gupta kings Chandragupta II and his son Kumaragupta I adopted the Western Satrap design (itself derived from the Indo-Greeks) with bust of the ruler and pseudo-Greek inscription on the obverse, and a royal eagle (Garuda, the dynastic symbol of the Guptas) replacing the Chaitya hill with star and crescent on the reverse.

The Rashtrakutas adopted Garuda as the dynasty emblem after the imperial Guptas.

The Rashtrakutas, who ruled a major part of the Indian subcontinent from the 8th to the 10th centuries CE, adopted Garuda as their dynasty emblem after the imperial Guptas. The Garuda is a mythical bird-like creature in Hindu mythology and is considered the mount of Lord Vishnu.

Background:
- The imperial Guptas, who ruled from the 4th to the 6th centuries CE, were one of the most influential dynasties in ancient India. They established a strong central administration and promoted art, architecture, and literature.
- The Guptas used the Garuda as their emblem, symbolizing their association with Lord Vishnu and their divine right to rule.

Reasons for adopting Garuda:
1. Continuity: The Rashtrakutas, like many other dynasties in ancient India, sought to establish their legitimacy by associating themselves with powerful symbols and emblems. By adopting the Garuda as their emblem, they sought to establish a link with the illustrious Gupta dynasty and its association with Lord Vishnu.

2. Religious significance: Garuda is considered a divine bird in Hindu mythology and is closely associated with Lord Vishnu, who is believed to be the preserver of the universe. By adopting Garuda, the Rashtrakutas sought to emphasize their religious piety and establish themselves as protectors of dharma (righteousness) and the Hindu faith.

3. Symbol of power: The Garuda is often depicted as a powerful and majestic creature, capable of carrying Lord Vishnu on its back. By adopting Garuda, the Rashtrakutas aimed to project an image of strength, power, and authority, asserting their dominance over their territories and subjects.

4. Cultural significance: The adoption of Garuda also had cultural significance. The Rashtrakutas were patrons of art, architecture, and literature, and by associating themselves with the Gupta emblem, they sought to align themselves with the rich cultural heritage of ancient India.

In conclusion, the Rashtrakutas adopted Garuda as their dynasty emblem after the imperial Guptas to establish their legitimacy, assert their authority, and align themselves with the religious and cultural traditions of ancient India.
