History has it that Humayun’s chief consort, Begum Bega or Haji Begam, started penning down the Emperor's life in Humayunama after his untimely death in 1556. She wanted the world to know about her dearest husband, and perhaps that's why she further commissioned the construction of a grand mausoleum in his honor. Mirak Mirza Ghiyas, a well-known Persian architect of that time, was invited to India to build the tomb. Nine years after his death, the construction of his tomb and the surrounding garden commenced in the year 1565.
After another seven years, in 1572, Humayun’s Tomb was finally completed. This mausoleum is considered as the first of its kind, with a perfect fusion of Persian and Indian architectures. Its grandeur and splendor were mind boggling, something that couldn’t be found in any other previously constructed Islamic architecture. It was centrally located in the Charbagh, a four-quadrant flower garden that represented the four rivers of the Quran. This was indeed the first time when an Islamic tomb was constructed in a flower garden, which further added to its significance in Indian history.
As per Humayun Tomb's history, in the 18th century, the flower garden surrounding the main building was converted into a vegetable garden due to negligence and lack of maintenance. Furthermore, in 1860, the entire premise was converted into an English-styled park when India was under colonial rule. It was Lord Curzon, the Indian viceroy, who commissioned the renovation of the Tomb's building and the restoration of the original flower bed garden. Later on, in 1993, it was declared as a UNESCO-protected site, thereby establishing its dominance in Indian heritage and history.
