Why is "Persian language in the Indian subcontinent" trending?

Wikipedia Overview

Before British colonisation, the Persian language was the lingua franca of the Indian subcontinent and a widely used official language in the northern India. The language was brought into South Asia by various Turco-Persianate and Afghan empires and was preserved and patronized by local Indian dynasties from the 11th century, such as the Sayyid dynasty, Tughlaq dynasty, Khilji dynasty, Mughal dynasty, Gujarat sultanate, and Bengal sultanate. Initially it was used by Muslim dynasties of India but later started being used by non-Muslim empires too. For example, the Sikh Empire, Persian held official status in the court and the administration within these empires. It largely replaced Sanskrit as the language of politics, literature, education, and social status in the subcontinent.
