The most popular theory is that Kālidāsa flourished during the reign of Chandragupta II, and therefore lived around the 4th-5th century CE. Several Western scholars have supported this theory, since the days of William Jones and A. B. Keith. Modern western Indologists and scholars like Stanley Wolpert also support this theory. Many Indian scholars, such as Vasudev Vishnu Mirashi and Ram Gupta, also place Kālidāsa in this period. According to this theory, his career might have extended to the reign of Kumāragupta I (r. 414 – 455 CE), and possibly, to that of Skandagupta (r. 455 – 467 CE).
