[UPSC CSE Pre 2023]

Detailed Solution & Historical Context

Concept

The 16th century saw a power struggle between regional Indian sultanates and rising European maritime powers. Bahadur Shah of Gujarat used territorial concessions as a diplomatic tool to seek help against the Mughal threat.

Authentic Source Evidence

In 1534, Bahadur Shah signed the Treaty of Bassein with the Portuguese. Under this agreement, he gave up Diu, Vasai, and the islands that currently make up Mumbai to the Portuguese authorities. Later, in 1559, Daman was also acquired by the Portuguese from the Gujarat Shah.

Analytical Breakdown

Logic 1: Bahadur Shah was facing a dual threat from the Mughal Emperor Humayun and internal rivals. Surrendering Diu was a strategic, albeit costly, move to secure Portuguese military support.

Logic 2: Other rulers like Mahmud Begarha were famous for expanding the Gujarat Sultanate and resisting early Portuguese incursions (like the Battle of Diu in 1509), rather than surrendering territory.

Conceptual Deep Dive & Logic

"What was the long-term impact of the Treaty of Bassein?"

It established a permanent Portuguese foothold in Western India, shifting the control of maritime trade routes from local sultanates to European naval powers.

Examiner's Mindset & Pro-Tip

"The surrender of Diu illustrates how local Indian rulers sometimes invited foreign powers into domestic conflicts, inadvertently paving the way for colonial expansion."
