Decolonisation is taking control of the narrative, instead of following the colonial history. But the Mughals or pre-British rulers were not colonisers. They were rulers and were invested in the land here. It is not decolonisation to remove the names of Mughals.  If you were removing the names of the Britishers whom we were an imperial colony of, but we were never the colony of the Mughals or the Ottoman empire. The Mughals emperors lived and worked in India, they were invested in India. They built India. Whatever they did, they did here. They cannot be called colonisers.
