Question: Who was Akbar's predecessor to the Mughal throne? Passage:Gauda was once the "capital of the ancient bhukti or political division of Bengal known as Pundravardhana which lay on the eastern extremity of the Gupta Empire." During the rule of the Sena Dynasty, in the 11th-12th century, Gauda was rebuilt and extended as Lakshmanawati (later Lakhnauti), and it became the hub of the Sena empire. Gauda was conquered by Muhammad bin Bakhtiyar Khalji in 1205. During the Turko-Afghan period, "the city of Lakhnauti or Gauda continued to function initially as their capital but was abandoned in 1342 by the Ilyas Shahi sultans in favour of Pandua because of major disturbances along the river course of the Ganga." "Pandua then lay on the banks of the Mahananda, which was the major waterway of the sultanate at the time. However, when the Mahananda too began to veer away from the site of Pandua in the mid-15th century, Gauda was rebuilt and restored to the status of capital city by the Hussain Shahi sultans"... With the ascent of Akbar to the Mughal throne at Delhi... the Mughals annexed the ancient region of Gauda in 1576 and created the Diwani of Bengal. The centre of regional power shifted across the Ganga to Rajmahal. Following the demise of the independent sultanate, the regional importance of the Gauda or Malda region declined irreversibly and the city of Gauda was eventually abandoned.
