Jahandar shah followed him to the throne as he was supported by the most powerful noble Zulfiqar khan. Zulfiqar khan controlled the administration and adopted a policy of tolerance towards chief of Mewar and Marathas. However against the Sikhs he continued the old policy of aggression. Soon the other nobles poisoned the emperor’s ears against Zulfiqar khan. He began secretly plotting against Zulfiqar khan. Finally Jahandar khan was killed by the next successor Farrukh Siyar.
Farrukh Siyar was undependable and worthless successor. The Sayyid brothers were instrumental in helping him win. They got important posts in the administration. The emperor wanted to rule personally but the Sayyid brothers believed that the he should be a puppet and they should handle administration to reverse the decay of the Empire. This led to conflicts between the emperor and the Sayyid brothers and finally the emperor was killed. In his place three successor princes were nominated. Two died quickly and the last Muhammad shah took the throne.
Under the Sayyid brothers the Mughal ties with Rajputs, Marathas and Jats were strengthened. But corruption had increased. The Sayyid's couldn’t rule properly due to continuous quarrels with other nobles. The death of the emperor had created public revulsion against them. The other nobles called the anti Islamic and anti Mughal due to their tolerant policy. The emperor too wanted to rule freely. Hence soon rebellion started against the Sayyid’s and they were killed.
Muhammad shah reigned for 30 years. An emperor who had sound knowledge of administration was needed to save the Empire but Muhammad shah wasn’t that. He led a life of luxury and pleasure. This disgusted his nobles and they left to carve semi independent states. The corruption too had increased under his reign. One such Wazir Nizam ul Mulk founded the south state of Hyderabad.
It was in this period the afghan king nadir shah descended in the north. He was attracted by the vast wealth. He invaded the North West frontier but met with no resistance. The nobles of Mughal court quarreled and wouldn’t unite even when the enemy was insight. This led to their heavy defeat. A bloodbath was seen in Delhi and Nadir Shah captured the Mughal treasury, Kohinoor diamond and the peacock throne. The Mughal emperor had been taken prisoner and released after he gave up all provinces west of Indus. After nadir shah the Mughals saw repeated attacks from Ahmed Shah Abdali. Abdali was nadir shahs ablest general and became the ruler of Afghanistan. He defeated the Marathas in 1761 at Panipat. The Mughal Empire had shrunk to just kingdom of Delhi but the Mughal never participated in the affairs of the state. Shah Alam II who ascended throne in 1759 spent the initial years wandering away from his kingdom as he was in mortal fear from his Wazir. He joined Shuja ud dawla and Mir Qasim in battle of Buxar against the English East India Company but was defeated. He remained as a pensioner in the Allahabad fort till 1772 and returned to Delhi under protective arm of the Marathas. When Delhi was captured by Marathas in 1803 till 1857 the Mughals were only political front of the British.
In fact after 1759 Mughals remained only because they symbolized political unity of the country in the minds of the people.
