Jahangir and Jahan
Jahangir
Akbar's son, Emperor Jahangir, readopted Islam as the state religion and continued the policy of religious toleration. His court included large numbers of Indian Hindus, Persian Shi'a and Sufis and members of local heterodox Islamic sects.
Jahangir also began building the magnificent monuments and gardens by which the Mughals are chiefly remembered today, importing hundreds of Persian architects to build palaces and create magnificent gardens.
Jahangir's approach was typified by the development of Urdu as the official language of Empire. Urdu uses an Arabic script, but Persian vocabulary and Hindi grammatical structure.
Jahan
The architectural achievements of the Mughals peaked between 1592 and 1666, during the reign of Jahangir's successor Jahan.

Jahan commissioned the Taj Mahal. The Taj Mahal marks the apex of the Mughal Empire; it symbolises stability, power and confidence.
The building is a mausoleum built by Jahan for his wife Mumtaz and it has come to symbolise the love between two people.
Jahan's selection of white marble and the overall concept and design of the mausoleum give the building great power and majesty.
Jahan brought together fresh ideas in the creation of the Taj. Many of the skilled craftsmen involved in the construction were drawn from the empire. Many also came from other parts of the Islamic world - calligraphers from Shiraz, finial makers from Samrkand, and stone and flower cutters from Bukhara.
By Jahan's period the capital had moved to the Red Fort in Delhi, putting the Fort at the heart of Mughal power. As if to confirm it, Jahan had these lines inscribed there: "If there is Paradise on earth, it is here, it is here."
Paradise it may have been, but it was a pricey paradise. The money Jahan spent on buildings and on various military projects emptied his treasury and he was forced to raise taxes, which aggravated the people of the empire.
