The move was strategic — Delhi offered better trade connectivity, a central location in the empire, and access to the Yamuna River. Other side, Agra looked over populated, suffering from space constraints for military movements and royal processions.

Construction of the fort began under the supervision of Ustad Ahmad Lahori, the same genius mind and hands behind the Taj Mahal. Completed in 1648, the fort remained the seat of Mughal power for nearly 200 years.

The Red Fort and India’s Independence

The significance of Red Fort in Indian history extends far beyond the Mughal era. During 18th century, Mughal authority collpased, but the fort always had its head high, silently observing the ups and downs.

In 1947, the Red fort of Delhi tied the most emotional connection with the people of India. On August 15, the day India gained independence, Prime Minister Jawaharlal Nehru hoisted the national flag at the Red Fort’s Lahori Gate. This tradition continued every year, starting since 1947, symbolizing the country’s unity and sovereignty. Every five year, a new Prime Minister addresses the nation of the Indpendence Day.
