Short answers, pulled from the story.
Emperor Akbar established the Agra Subah as a core province of the Mughal Empire during his reign in the sixteenth century. This administrative decision transformed Agra into one of the empire's most critical territories for decades.
To the north, the province bordered Delhi and Awadh provinces directly while eastern borders met Allahabad territory. Southern and western edges touched Malwa and Ajmer lands to define the physical limits of the Agra Subah throughout its existence.
Abul Fazl-i-Allami recorded thirteen sarkars within the province during Akbar's reign including Kalpi, Kannauj, Kol, Gwalior, Erach, Payanwan, Narwar, Mandlaer, Alwar, Tijara, Narnaul, and Sahar. Sarkar Agra served as the capital district among these administrative units.
Wazir Khan also governed the province before being transferred to Lahore between 1628 and 1631. Qasim Khan held the position of subahdar during the mid-seventeenth century under Shah Jahan alongside other officials like Raja Bethal Das.
The Agra Subah eventually lost prominence following the rise of the Maratha Empire which shifted the balance of power across India. Rapid expansion by Maratha forces caused core territories like Agra to become eclipsed by newer political entities emerging in the eighteenth century.
