No, Maharani is a fictional story.
The series, while inspired by Bihar's political landscape, presents a dramatized and fictional narrative. It follows Rani Bharti, a homemaker suddenly thrust into the role of Chief Minister after her husband, the current CM, resigns. The plot revolves around her navigating the complex world of politics, dealing with corruption, and challenging established power structures. While elements of the story might reflect real-world political scenarios and figures, the core narrative and character arcs are products of creative writing. The primary focus is on entertainment and dramatic storytelling, not historical accuracy.
