who shifted capital of magadh from rajagrih to patliputra
Magadha Accounts differ slightly as to the cause of King Ajatashatru's war with the Licchavi, an area north of the river Ganges. It appears that Ajatashatru sent a minister to the area who worked for three years to undermine the unity of the Licchavis. To launch his attack across the Ganges River, Ajatashatru built a fort at the town of Pataliputra. Torn by disagreements the Licchavis fought with Ajatashatru. It took fifteen years for Ajatashatru to defeat them. Jain texts tell how Ajatashatru used two new weapons: a catapult, and a covered chariot with swinging mace that has been compared to a modern tank. Pataliputra began to grow as a centre of commerce and became the capital of Magadha after Ajatashatru's death.
History of Delhi The third and greatest Mughal emperor, Akbar, moved the capital to Agra, resulting in a decline in the fortunes of Delhi. In the mid-17th century, the Mughal Emperor Shah Jahan (1628–1658) built the city that sometimes bears his name Shahjahanabad, the seventh city of Delhi that is more commonly known as the old city or old Delhi. This city contains a number of significant architectural features, including the Red Fort (Lal Qila) and the Jama Masjid. The old city served as the capital of the later Mughal Empire from 1638 onwards, when Shah Jahan transferred the capital back from Agra. Aurangzeb (1658–1707) crowned himself as emperor in Delhi in 1658 at the Shalimar garden ('Aizzabad-Bagh) with a second coronation in 1659. After 1680, the Mughal Empire's influence declined rapidly as the Hindu Maratha Empire rose to prominence.[24]
