By the late 17th century, the Mughal Empire was as its peak and had expanded to include almost 90 per cent of South Asia, and enforced a uniform customs and tax-administration system.
In the 18th century, Mughals were replaced by the Marathas as the dominant power in much of India, while the other small regional kingdoms who were mostly late Mughal tributaries such as the Nawabs in the north and the Nizams in the south, declared an autonomy.
