What were some causes of the decline of the mogul empire?

Answer 1

After Emperor Aurangzeb's death in 1707, the empire fell into succession crisis. Barring Muhammad Shah, none of the Mughal emperors could hold on to power for a decade. In the 18th century, the Empire suffered the depredations of invaders like Nadir Shah of Persia and Ahmed Shah Abdali of Afghanistan, who repeatedly sacked Delhi, the Mughal capital. Most of the empire's territories in India passed to the Marathas, Nawabs, and Nizams by c. 1750. The Mughal Emperors lost effective power in favor of the British after the Battle of Buxar in 1764.[13] In 1804, the ineffective Shah Alam II formally accepted the protection of the British East India Company. The company had already begun to refer to the weakened emperor as "King of Delhi", rather than "Emperor of India". The once glorious and mighty Mughal army was disbanded in 1805 by the British; only the guards of the Red Fort were spared to serve with the King of Delhi, which avoided the uncomfortable implication that British sovereignty was outranked by the Indian monarch. Nonetheless, for a few decades afterward the British East India Company continued to rule the areas under its control as the nominal servants of the emperor and in his name. After the Revolt of 1857, even these courtesies were disposed. The rebels declared their allegiance to Shah Alam's descendant, Bahadur Shah II which led to a protracted Siege of Delhi, after which the victorious British abolished the institution altogether with transfer of authority to the British crown. The last Mughal emperor was deposed and exiled to Burma, where he died in 1862.
