At a very young age she was married to Raja Gangadhar Rao, the Maharaja of Jhansi. After the death of her husband, she adopted a son and appointed him as a successor of Jhansi. But on the pretext that adopted son is not entitled to throne the British annexed Jhansi from her. Rani was not ready to give up Jhansi to Britishers which rightfully belonged to her.
In March 1858, the Britishers attacked Jhansi. With her trusted warriors Rani Laxmi Bai fought for about two weeks against the British. However, after this great war, Jhansi fell to the British forces. When the situation was not in control, Rani of Jhansi with some of her warriors departed from Jhansi. But regrouped her warriors and she captured Gwalior, which was under the control of British then. Again a fierce battle took place. Rani Laxmi Bai fought with deathless patriotism and martyrdom. However on the second day of battle,on 18th June of 1858 she lost her life at the very young age of 22.
