The mosque you see in the picture is located in District Darbhanga just next to a wall of a fort of Maharaja of Darbhanga. It was originally built approx. in 1737 during the era of Ali Vardi Khan as Naib-Nazim of Bihar. It was Ali Vardi Khan who honoured the Zamindars of Tirhut with the title of Raja and awarded a large tract of land as well. In the later era, these Zamindars became the Maharajas of Darbhanga and were inarguably the richest landlords of India during the British Era.
The Maharaja instructed to change the design & built the wall in such a way that the mosque is not disturbed, accordingly the design was made to leave space for the mosque and the mosque remained intact at its original location. The mosque stands to this day adjacent to the wall of the fort, known as JHAGADUA MASJID.
I am surprised at the name as there did not arise any dispute (Jhagda) as such. The munificence of Maharaja can be gauged further that since all the Muslim population got shifted to new places
, the Maharaja granted a piece of land to start a madarsa in front of the mosque so that the mosque is taken care of well and is populated.
Something about the Maharajas of Darbhanga – The chiefs of this family were deeply religious, devoted to Sanskrit traditions and were huge supporters of orthodox Hindu practices in both caste and religion. Shiva and Kali were the main deities of the royal family. People don’t realize but they played the most important role in preservation of old manuscripts and popularization of Sanskrit language. As part of their attempt to reintroduce old Hindu customs such as the study of Vedas and Vedic rites, the Maharaja reintroduced Samavedic study by inviting a few well-versed Samavedins from south India to teach there.
The Raj was considered to be the embodiment & protector of Mithila and Maithili language as well. Maharaja Rameshwar Singh established Sri Bharat Dharma Mahamadal, a neo-conservative Hindi organisation that sought to make Hindu scriptures available to all castes and women. He was instrumental in publishing old Tantric texts in English and other language.
Keeping in view that the Maharajas were deeply religious, we must appreciate how great they were ,being so humane and considerate in their outlook. The palace area in Darbhanga has three tombs of Muslim saints along with a small mosque. There are mazars at GM Road, Denby Road and one in the middle of the road near Darbhanga Tower. A tomb of a Muslim saint is located next to Anandbagh Palace.
Trivia -Surprisingly when the work was in full swing in 1939–40 and the three sides of the fort were constructed, an Agrawal family of Banglagarh objected and filed a suit in the court that owing to the construction of high walls , he will be deprived of the proper sunlight in his courtyard. The litigation took some time and finally the Agrawals won the case and the construction of the fourth (West) side of the wall was stayed by the high court. After a few years the country got independence and soon the Zamindaris got abolished. The fourth side of the wall remained unconstructed and unfinished.
