Before lal qila name India today chenge name Bharat

It seems you're asking about the historical name of India's famous Red Fort, which was originally known as "Qila-e-Mubarak" or "Lal Qila" during the Mughal era. After India gained independence in 1947, it was commonly referred to as the "Red Fort." However, the name "Lal Qila" is still used, and its official name hasn't been changed to "Bharat" as of my last knowledge update in September 2021. If there have been any changes since then, I wouldn't have that information.
