Battle of Diu: Obscure Turning Points

Introduction

The Battle of Diu, fought on February 3, 1509, was a significant naval conflict between the Portuguese Empire and a coalition of forces including the Sultanate of Gujarat, the Mamluk Sultanate of Egypt, the Zamorin of Calicut, and the Republic of Venice. This battle occurred near the port of Diu, located on the western coast of India.

Background of the Battle

• (1) One of the pivotal moments in world history was the 16th century, the era of exploration and colonization, when previously separate cultures and civilizations became aware of one another and were connected by new sea routes. For some civilizations, such as the indigenous peoples of the Americas, this contact would be disastrous, while for others, such as Spain and the Netherlands, it became the stepping stone to vast wealth and far-flung colonial empires.
• (2) Most of the earliest European voyages of exploration were motivated by the desire to find a new seaborne path to India, Southeast Asia, and China, fabled lands of limitless riches—the source of rare spices, silk, and other prized luxury items.
• (3) The reason for this search for a sea route was that all the land routes were controlled by Muslim powers that reaped most of the profits from the trade that passed through their territories.
• (4) Islam had grown rapidly, and its dominion stretched from the Balkans deep into Africa and east to northern India. Fueling this expansion was the Islamic states’ stranglehold on the lucrative Eastern trade routes.
• (5) By contrast, Christianity was confined to Western Europe, hemmed into the south and east by Islamic states. In technological terms, too, Europe seemed to be stagnating during the Middle Ages, while such Muslim cities as Baghdad became centers of innovation and learning.
• (6) Seafaring in the East at this time was similar to that practiced in the classical world, with a long, narrow galley propelled by hundreds of oars. Such vessels had an extremely limited range, rarely ventured out of sight of land, and could operate only in calm or enclosed waters.
• (7) But here was one area of technology in which Western Europe had advanced: seafaring on the open seas. At the close of the 15th century, Europe had begun to produce deep-bellied, square-rigged ships capable of braving and even crossing the great oceans. This type of ship could also be armed by cutting holes along the sides and adding rows of cannons.
• (8) Although many countries concentrated their efforts on sailing west, the seafarers of Portugal focused on an eastern route. They journeyed south around the tip of Africa, then explored the coastline back north toward the Arabian Peninsula.

The Battle

• (1) By 1500, Portuguese mariners eventually found themselves in India. The Arabic merchants who controlled the trade were not pleased to encounter the Portuguese in their territory; seeing opportunity, however, the Portuguese seized several ports and raided Arabic shipping.
• (2) The king of Portugal then dispatched a fleet of 21 ships under the command of Dom Francisco de Almeida, with orders that show a remarkably practical understanding of geopolitics and economics: “Nothing would serve us better than to have a fortress at the mouth of the Red Sea … because from there we could cut off the spices… and all those in India from now on could only trade through us.”
• (3) Correctly perceiving Almeida’s expedition as a threat to their monopoly, an unlikely coalition of Mamluks of Egypt, Ottoman Turks, and ships from the local Indian rulers banded their naval forces together to oppose him. The Venetian Republic also felt threatened by the Portuguese and offered assistance.
• (4) Almeida caught up with the combined fleet at the Indian port of Diu in 1509 and sailed boldly in to attack them. Almeida had 1,200 men on 19 oceangoing ships, 12 of which were of a carrack design and 7 of a caravel type.
• (5) The combined fleet opposing him numbered more than 200 vessels: 80 to 100 war galleys and the rest dhows and other small coastal craft.
• (6) The battle was a wild melee, with the sturdy Portuguese ships firing broadsides from their rows of cannons while the swarms of galleys and other boats attempted to ram or run alongside and board. The battle was a disaster for the combined fleet, which was nearly entirely wiped out.
• (7) Over the next several decades, there would be at least three more major naval battles between Portuguese ships and Muslim fleets along the northwestern coast of India, but all would end the same way.

Outcomes of the battle

• (1) Diu marked the moment when Europe finally broke free of the crippling Islamic monopoly on trade with the East and began its steady rise to world dominance. The economic shift resulting from the battle also set into motion the slow decline and eventual disintegration of the once-mighty Ottoman Empire.
• (2) What the Battle of Diu fundamentally determined was that the ultimate victor in the rivalry to control the rich trade with the East would be a Christian European power, not a Muslim one, an outcome that can truly be said to have profoundly shaped the rest of world history.

Conclusion

The Battle of Diu concluded with a decisive Portuguese victory, which had profound and far-reaching consequences for global trade and geopolitics. The Battle of Diu stands as a turning point in the shift from traditional overland trade routes, such as the Silk Road, to maritime routes dominated by European powers. It set the stage for the age of European imperialism and the global reconfiguration of trade networks, which would shape the course of world history for centuries to come.
