Shahjahanabad was founded by the Mughal Emperor Shah Jahan in 1639 as the new capital of the Mughal Empire, shifting the capital from Agra to Delhi. The city was officially named Shahjahanabad and was designed as a walled city, with the Red Fort (Lal Qila) as its centerpiece, serving as the imperial palace and symbol of Mughal authority. The foundation of the city was laid with the involvement of Shah Jahan's daughter, Jahanara, who played a key role in its establishment. Shahjahanabad became a vibrant cultural, political, and commercial hub, reflecting the grandeur and architectural brilliance of the Mughal era
