The Nagarjunakonda inscriptions are the earliest known substantial South Indian Sanskrit inscriptions, probably from the late 3rd century or early 4th century CE, or both. These inscriptions are related to Buddhism and the Shaivism tradition of Hinduism. A few of these inscriptions from both traditions are verse-style in the classical Sanskrit language, while some such as the pillar inscription is written in prose and a hybridized Sanskrit language. An earlier hybrid Sanskrit inscription found on Amaravati slab is dated to the late 2nd century, while a few later ones include Sanskrit inscriptions along with Prakrit inscriptions related to Hinduism and Buddhism. After the 3rd century CE, Sanskrit inscriptions dominate and many have survived. Between the 4th and 7th centuries CE, south Indian inscriptions are exclusively in the Sanskrit language. In the eastern regions of South Asia, scholars report minor Sanskrit inscriptions from the 2nd century, these being fragments and scattered. The earliest substantial true Sanskrit language inscription of Susuniya (West Bengal) is dated to the 4th century. Elsewhere, such as Dehradun (Uttarakhand), inscriptions in more or less correct classical Sanskrit inscriptions are dated to the 3rd century.
