Why is "Tamil copper-plate inscriptions" trending?

Wikipedia Overview

Tamil copper-plate inscriptions are copper-plate records of grants of villages, plots of cultivable lands or other privileges to private individuals or public institutions by the members of the various South Indian royal dynasties. The study of these inscriptions has been especially important in reconstructing the history of Tamil Nadu. The grants range in date from the 10th century C.E. to the mid-19th century C.E. A large number of them belong to the pandyas, the Cholas. These plates are valuable epigraphically as they give us an insight into the social conditions of medieval South India; they also help us fill chronological gaps in the connected history of the ruling dynasties. For example, the Leyden grant of Parantaka Chola and those of Parakesari Uttama Chola are among the most important, although the most useful part, i.e., the genealogical section, of the latter's plates seems to have been lost
