After Baber had annexed India he set out to consolidate his positions and he determined to make his kingdom so invulnerable and powerful that no other power would ever dare set eyes upon his adopted country. This quest of his was soon fulfilled, and he succeeded in this enterprise to a very great extent. Gradually he won over all the Rajputs, and the once blood-thirsty Hindus and Muslims settled down to live as one common people. Into this common feeling of brotherhood, the Royal Family too joined in. There was a Rajput Princes called Rajkumari whose father had been killed in the war, but the girl on Baber's express command had been reinstated on her father's throne. The Emperor was very fond of her and treated her as if she was his own daughter. Prince Humayun in his turn, had become attached to her, to regard her as his sister. All this common brotherhood did much to enhance the prosperity of the land, and resulted in the thriving to education and self-respect. This helped to foster numerous learned poets, philosophers and warriors.
But on Humayun ascending his father's throne, there sprung up discontent in certain quarters, and between Humayun and Sher Shah- there followed intensive battles. Under the banner of Moghuls, many a Muslim and Rajput youth flocked, and as an incentive for inspiration Humayun himself rode at the head of his army. New came to Humayun that Bahadur Shah, Wali of Ahmedabad had surrounded the territory of Rajkumari- his Rajput sister. He immediately mustered to her aid, and with a force of 50,000 brave men decided to save her. Many an advisers requested him not to take this step, and many expressed the opinion that he would suffer much a defeat that he would lose his kingdom, if he were to create another front. His reply was befitting and none could have furnished a better one. He said that a lost kingdom may be won back, but the dignity and prestige of a defeated sister could never be retrieved.
This first common feeling of unity amongst the Hindus and Muslims will be shown in the film "HUMAYUN".
If you mediate and ponder over it, you will find that there's a lot in it, but if you choose to forget, it is just a story.
