Correct Option
The correct option is (a) 1 - 3 - 4 - 2.
Explanation
The history of ancient India is marked by the rise of the first pan-Indian empire (Mauryas), followed by a period of political fragmentation and foreign invasions in the northwest (Post-Mauryan period), culminating in the establishment of the classical Gupta Empire.
Chronological Analysis
- 1. Mauryas (c. 321 BCE – 185 BCE): The Mauryan Empire was established by Chandragupta Maurya in the 4th century BCE. It was the earliest of the dynasties listed and disintegrated in the early 2nd century BCE.
- 3. Indo-Greeks (c. 180 BCE – 10 CE): Following the decline of the Mauryas, the Indo-Greeks (Bactrian Greeks) were the first series of foreign rulers to invade and establish control over northwestern India. Menander is a notable ruler from this period.
- 4. Kushanas (c. 30 CE – 375 CE): The Kushanas established their rule significantly later, following the Indo-Greeks, Shakas, and Parthians. Their empire reached its zenith under Emperor Kanishka in the 1st and 2nd centuries CE.
- 2. Guptas (c. 319 CE – 550 CE): The Gupta era began in the 4th century CE with the accession of Chandragupta I, marking the end of the post-Mauryan fragmentation and the beginning of a new imperial age.
Conclusion: The correct chronological order is Mauryas (1) → Indo-Greeks (3) → Kushanas (4) → Guptas (2).
Key Takeaway
The sequence of major powers in ancient India is: Mauryan Empire → Post-Mauryan Foreign Invasions (Indo-Greeks → Shakas → Parthians → Kushanas) → Gupta Empire.
