Step 1: Identify the historical context of the Slave Dynasty.
The Slave Dynasty, also known as the Mamluk Dynasty, was the first dynasty to rule the Delhi Sultanate in India.
It ruled from 1206 to 1290.
Step 2: Recall the founder.
The founder of the Slave Dynasty was Qutb-ud-din Aibak.
He was a former slave of Muhammad Ghori (Mu'izz ad-Din Muhammad Ghori).
After Ghori's assassination in 1206, Aibak declared himself Sultan of Delhi and established the dynasty.
Step 3: Evaluate other options.
- (1) Muhammad Bin Tughlaq: A prominent ruler of the Tughlaq Dynasty (1320-1414), which succeeded the Khalji Dynasty and preceded the Sayyid Dynasty.
He ruled from 1325 to 1351.
- (3) Khizr Khan (Kizar Khan): The founder of the Sayyid Dynasty (1414-1451), which ruled the Delhi Sultanate after the Tughlaqs.
- (4) Ibrahim Lodi: The last ruler of the Lodi Dynasty (1451-1526).
He was defeated and killed by Babur in the First Battle of Panipat in 1526, which marked the beginning of the Mughal Empire in India.
Step 4: Confirm the founder.
Qutb-ud-din Aibak was the founder of the Slave Dynasty.
This matches option (2).
