In 1810, the Qajar governor of Fars, under the orders of Fath Ali Shah Qajar, launched an expedition against Bahrain to expel the Wahhabis and reassert Persian control. The campaign was part of a broader effort to push back against Wahhabi influence in the Gulf and support local rulers opposed to Saudi dominance

The Qajar Invasion of Bahrain (1810)

1. The Qajar Naval Force

The Qajar fleet, consisting of warships and troop transports, set sail from Bushehr, the main Persian port on the Gulf. Their objective was to quickly overwhelm the Wahhabis defenders and reinstate Persian control over the island.

2. The Siege Begins

Upon reaching Bahrain, the Qajars blockaded the island, cutting off supplies and reinforcements. Persian forces launched artillery bombardments and amphibious assaults, attempting to break the defenses of Abdullah bin Ahmad Al Khalifa.

Despite being outnumbered, the Wahhabi-aligned Bahraini forces put up fierce resistance, using fortified positions to repel Persian advances. Reinforcements from Najd (Saudi heartland) also arrived to bolster the defense

Aftermath

Persian Claims – the 1810 invasion was a Success, Persia continued to claim Bahrain, leading to further conflicts.
Wahhabi Intervention – The siege demonstrated Bahrain’s strategic importance, leading to increased wahhabis involvement in the Gulf to counter Persian influence

Conclusion

The Siege of Bahrain (1810) was a crucial episode in the power struggle between Qajar Persia and the Wahhabi-aligned First Saudi State. While Persia Succeeded to claim Bahrain, the battle of Manama reflected the broader geopolitical contest for dominance in the Persian Gulf—a conflict that would shape the region for decades to come
