Gupta empire, 319 - 467 CE, viewed by historians as golden age of India; Many Hindu epics and Puranas claimed to have been 'canonized' or committed to written texts then

I don't know how accurate the extracts I have given below from Gupta empire wiki page are. But I think they are noteworthy as that seems to be how academic historians are viewing them, and so that's what would probably be taught in educational institutions.

Some extracts from https://en.wikipedia.org/wiki/Gupta_Empire :

The Gupta Empire was an ancient Indian empire which existed from the early 4th century CE to late 6th century CE. At its zenith, from approximately 319 to 467 CE, it covered much of the Indian subcontinent.[4] This period is considered as the Golden Age of India by historians.[5][note 1] The ruling dynasty of the empire was founded by the king Sri Gupta; the most notable rulers of the dynasty were Chandragupta I, Samudragupta, and Chandragupta II, also known as Vikramaditya. 

...

The high points of this period are the great cultural developments which took place primarily during the reigns of Samudragupta, Chandragupta II and Kumaragupta I. Many Hindu epics and literary sources, such as Mahabharata and Ramayana, were canonised during this period.[10] The Gupta period produced scholars such as Kalidasa,[11] Aryabhata, Varahamihira, and Vatsyayana who made great advancements in many academic fields.[12][13][14] Science and political administration reached new heights during the Gupta era.[13] The period gave rise to achievements in architecture, sculpture, and painting that "set standards of form and taste [that] determined the whole subsequent course of art, not only in India but far beyond her borders".[15] Strong trade ties also made the region an important cultural centre and established the region as a base that would influence nearby kingdoms and regions in India and Southeast Asia.[16][unreliable source?] The Puranas, earlier long poems on a variety of subjects, are also thought to have been committed to written texts around this period.[15][17] Hinduism was followed by the rulers and the Brahmins flourished in the Gupta empire but the Guptas tolerated people of other faiths as well.[18]

Kalidasa wrote ... with an excellence which, by unanimous consent, justifies the inevitable comparisons with Shakespeare ... When and where Kalidasa lived remains a mystery. He acknowledges no links with the Guptas; he may not even have coincided with them ... but the poet's vivid awareness of the terrain of the entire subcontinent argues strongly for a Guptan provenance.

Many Hindu epics including Mahabharata and Ramayana were canonized during this period! Hmm. I wonder what exactly that means. Perhaps it means that some standard form of these epics emerged and which standard form was written down and passed down to future generations. Well, that's a very interesting claim. But I wonder how accurate the claim is. I mean, what sort of data is there to back such a claim? Is it more conjecture than evidence based?

Similarly the above extracts say that Puranas are thought to have been committed to written form in this period. Hmm. That's another very interesting claim but one wonders how accurate it is.

An interesting point to note is that while the earlier Mauryan empire seems to have promoted Buddhism but was tolerant of Hinduism and other faiths like Jainism, the Gupta empire seems to have promoted Hinduism but was tolerant of other faiths like Buddhism and Jainism.
