Gurudwara Bangla Sahib is situated in the heart of New Delhi’s Cannaught Place area. It is loacted on the east side intersection of Ashok Road and Baba Kharag Singh Marg. Originally this place was the Bungalow(haveli) of Mirza Raja Jai Singh, hence the name Bangla Sahib. It’s original name was Jaisinghpura Palace.
Mirza Raja Jai Singh was an important military leader of Mughal emperor Aurangzeb. After the passing away of Guru Har Rai the seventh Sikh Guru, Ram Rai and his masands(masand is derived from Arabic word masnad, meaning delegating authority of the sovereign) instigated Mughal Emperor Aurangzeb to issue a decree summoning Guru Harkrishan to his court. Ram Rai was elder brother of Guru Harkrishan. Guru Harkrishan decided to go to Delhi since he felt that the “sangat”, his followers had been misguided and he saw an oppurtunity in this to clear their misunderstandings. Meanwhile Sikhs of Delhi approached Mirza Raja Jai Singh, a strong devotee of Sikh Gurus to prevent any harm coming to Guru Harkrishan either by Aurangzeb or by the masands of Ram Rai.
Ram Rai when learned that Guru Harkrishan had accepted the summons to appear before Aurangzeb in his court at Delhi, started rejoicing since Guru Harkrishan had taken a vow not to appear before Aurangzeb. If Guru Harkrishan Comes to Delhi and refuses to meet Aurangzeb then definitely he will be arrested and suffer humiliation. Now Ram Rai felt that this act of Guru Harkrishan will surely lower his prestige among his followers and will pave the way for Ram Rai to declare himself as the true successor of Guru Har Rai. Mirza Raja Jai Singh had made elaborate arrangements to receive Guru Harkrishan. Guru Harkrishan was received on the outskirts of Delhi like a royal guest of honor. Guru Harkrishan was accompanied by prominent Sikhs from his darbar and his mother Sulakhni.
