The Myth of the Sword and the Faith: Unmasking the Realpolitik of Futuhat and the Illusion of Holy War

When the modern world discusses the history of Islamic territorial expansion (Futuhat), two equally misleading narratives dominate the stage. On one side, Western critics arrogantly accuse Islam of being a bloodthirsty religion spread by the edge of the sword. On the other side, Islamic fundamentalists romanticize past military conquests as a theological “holy war” that must be resurrected today to restore religious supremacy.

Both factions are completely blind to one fundamental reality: The Geopolitics of the 7th Century.

Evaluating the military maneuvers of the early Islamic Caliphate through the lens of post-World War II Human Rights and the UN Charter is a fatal academic flaw. Let us remove those modern lenses and view the past as it truly was: a bloody arena governed solely by the Right of Conquest—a world of “eat or be eaten.”

At that time, the Arabian Peninsula was sandwiched between two tyrannical and aggressive superpowers: the Eastern Roman (Byzantine) Empire and the Persian (Sassanid) Empire. For a nascent state emerging in Medina, remaining passive within its borders without projecting military strength was an open invitation to be crushed and colonized. The territorial expansion during the era of the Rashidun and Umayyad caliphates was, at its geopolitical core, a pre-emptive strike—an absolute necessity to secure state sovereignty from the looming threats of northern superpowers.

But the critical question arises: Why couldn’t Dawah (Islamic preaching) be conducted peacefully across those borders without the need for invasion?

This is where modern historical blindness becomes apparent. In the 7th century, you could not peacefully spread any ideology across national borders. Byzantium and Persia were not modern democracies. They were fascist regimes with a “State Religion” violently enforced upon their subjects. There was no freedom of expression, let alone freedom of religion.

If Muslim emissaries had arrived bearing pamphlets or preaching in the public squares of Damascus or Persia, they would not have been greeted with theological debate. They would have been arrested, branded as political subversives, and executed on the spot.

Therefore, military conquest became an absolute necessity. The goal of Futuhat was not to hold a sword to the throats of peasants to force the Shahada (declaration of faith). The sword was swung to decapitate the “head of state”—to demolish the tyrannical political institutions that built walls against religious freedom. Only after the regime was overthrown and the territory fell under Islamic political authority did that wall crumble. Only then were the people free to hear the message and choose their faith without the threat of execution by their own kings. Islam conquered the political territory, not the hearts of the people by force.

The most brutal evidence destroying the “spread by the sword” myth lies in the economic reality of the era. Non-Muslim inhabitants (Dhimmi) in conquered territories were required to pay a protection tax called Jizyah. If the Caliphate had forced millions of Persians and Syrians to convert to Islam overnight, the state treasury would have instantly gone bankrupt as the source of Jizyah vanished. The mass conversion of the Middle East into a Muslim-majority region did not happen overnight; it took centuries of organic assimilation, intermarriage, and social class shifts.

Furthermore, if military conquest was an absolute theological requirement for spreading the faith, why did Islam reach Nusantara (the Indonesian archipelago) and become the majority religion without a single Arab armada bombarding the coasts of Java or Sumatra?

The answer is that the Hindu-Buddhist kingdoms in Nusantara, such as Majapahit and Srivijaya, were highly pragmatic maritime thalassocracies. They welcomed foreign merchants with open arms. In Nusantara, the “fascist wall” did not exist. Because access to information and social interaction was not blocked by local ruling regimes, the sword of Islam never needed to be drawn from its scabbard.

Military conquest in early Islamic history was not a theological prerequisite, but a medieval geopolitical tool pragmatically used to dismantle authoritarianism. Today, when national borders are regulated by international law and the “fascist walls” have been replaced by the internet, romanticizing military invasion as a part of Dawah is a regression of intellect that endangers the very essence of the religion itself.
