Begum Samru, also known as Zebunnissa, emerged as a formidable leader following her husband's passing. She skillfully led armies and safeguarded her Sardhana Jagir, earning the respect of neighboring rulers. Embracing Christianity, she funded the construction of a stunning church in Sardhana, the Basilica of Our Lady of Graces, which remains a testament to her legacy.
The church was honored with basilica status by Pope John XXIII in 1961.
