I want to know the answer to the following question:
What is the name of the empire for which Delhi served as the political and financial capital from 1649 to 1857?
All the background I'm provided with is that "During the early 1900s, a proposal was made to the British administration to shift the capital of the British Indian Empire (as it was officially called) from Calcutta to Delhi.". Is that enough to answer the question?
Answer: no
