Kālidāsa
The most popular theory is that Kalidasa flourished during the reign of Chandragupta II, and therefore lived around 4th-5th century CE. Several Western scholars have supported this theory, since the days of William Jones and A. B. Keith. Many Indian scholars, such as Vasudev Vishnu Mirashi and Ram Gupta, also place Kalidasa in this period. According to this theory, his career might have extended to the reign of Kumaragupta I (r. 414 – 455 CE), and possibly, to that of Skandagupta (r. 455 – 467 CE).
Kannada literature
The Vaishnava Bhakti (devotional) movement involving well-known Haridasas (devotee saints) of that time made an indelible imprint on Kannada literature starting in the 15th century, inspiring a body of work called "Haridasa Sahitya" ("Haridasa literature"). Influenced by the Veerashaivism of the 12th century, this movement touched the lives of millions with its strong current of devotion. The Haridasas conveyed the message of Vedantic philosopher Madhvacharya to the common man through simple Kannada language in the form of "devaranamas" and "kirthanas" (devotional songs in praise of god). The philosophy of Madhvacharya was spread by eminent disciples including Naraharitirtha, Jayatirtha, Vyasatirtha, Sripadaraya, Vadirajatirtha, Purandara Dasa, and Kanaka Dasa. Chaitanya Mahaprabhu, a prominent saint from distant Bengal, visited the region in 1510, further stimulating the devotional movement.
