At his death in 1605, his son Jahangir comes to power. Historians consider Jahangir to be relatively tolerant like Akbar, and to continue the interest in the sciences and the arts that you saw in the Mughal court under Akbar, but he's a little bit more controversial. As we talked about in the Sikhism video, he famously tortures and executes Guru Arjan. Some would say it was because Guru Arjan was siding with Jahangir's son who was trying to rebel. Others would say that it was because Guru Arjan was getting a following in Punjab and that Jahangir was insecure of his own hold on power and decided to execute Guru Arjan, but he is succeeded by his son Shah Jahan, who becomes decisively less tolerant. His reign, however, is known as the golden age of Mughal architecture with the crowning achievement, arguably, the Taj Mahal, which is a mausoleum that he commissions in the 1630s to house the body of his dead wife. As you can see here, it's housed in Agra, and Agra and Delhi, at various points during the Mughal Empire, are the capital.
