Assertion: In the Mughals, every dynastic change was accompanied and decided by a fratricidal war.

Reason: In the Mughal empire there was no law laying down which of the emperor’s sons would succeed to the throne. 

Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

In a painting by Abu'l Hasan, Akbar is dressed in white, associated in Sufi traditions with the enlightened soul. He proffers a globe, symbolic of dynastic authority. In the Mughal empire there was no law laying down which of the emperor’s sons would succeed to the throne. This meant that every dynastic change was accompanied and decided by a fratricidal war. Towards the end of Akbar’s reign, Prince Salim revolted against his father, seized power and assumed the title of Jahangir.
