610-945 CE
From 610 to 945 CE, the Arabs erupted from the desert with a revelation that reshaped the world, carrying the Quran in one hand and a sword in the other. Within a century of Muhammad's death, their empire stretched from Spain to Central Asia — the fastest conquest in history, fueled by faith, commerce, and the unification of tribes who had never before marched together.
The Arabs were Semitic peoples of the Arabian Peninsula — desert nomads and oasis merchants who had lived for centuries on the margins of the great empires. Romans and Persians hired them as auxiliaries and traded with their caravans, but neither thought them capable of challenging civilized power. They were wrong. In 610 CE, a merchant named Muhammad received the first of the revelations that would become the Quran, and within decades his followers had overthrown the Persian Empire entirely and stripped Byzantium of its richest provinces. The Arabs who emerged from this transformation were no longer marginal; they were masters of a civilization stretching from the Atlantic to the Indus.
What made this explosion possible was Islam itself — not merely as spiritual motivation but as political technology. The new faith provided a framework for uniting fractious tribes, a legal system for governing diverse populations, and a sense of divine mission that made impossible victories seem inevitable. Arab identity fused with Islamic identity so completely that for centuries the two were nearly synonymous, even as Persians, Berbers, and Turks converted and brought their own contributions to the civilization Arabs had founded.
The Arabian Peninsula was a land of extremes: vast deserts where nothing lived, scattered oases where date palms grew, and coastal strips where fishing villages clung to existence. The Bedouin who wandered the interior lived by herding camels and goats, raiding rival tribes, and guiding caravans through landscapes only they could navigate. The settled Arabs of Mecca and Medina were merchants who grew wealthy on trade routes connecting the Mediterranean to the Indian Ocean — frankincense and spices flowing north, manufactured goods returning south.
This harsh environment shaped Arab character. Hospitality was sacred because survival in the desert depended on strangers sharing water and shelter. Poetry was treasured because it preserved tribal memory and reputation. Warfare was endemic because scarce resources meant constant competition. Islam channeled these traits into new directions: hospitality became charity mandated by faith; poetry celebrated the Prophet and his companions; warfare became jihad, struggle in God's cause. The Arabs carried their desert values into the conquered lands, adapting them to rule cities they had never imagined.
Arab armies conquered with speed that still astonishes historians. Within ten years of Muhammad's death, they had destroyed the Sasanian Empire and driven Byzantium from Syria, Palestine, and Egypt. Within a century, they ruled from Spain to Sindh. Their military advantages were multiple: light cavalry perfectly adapted to desert and steppe warfare, religious motivation that made martyrdom desirable, and the exhaustion of their enemies — Persia and Byzantium had fought each other to mutual ruin in the decades before Islam emerged.
Yet the Arabs were always a minority in their own empire. They conquered as warriors and ruled as aristocrats, but the populations they governed — Persians, Syrians, Egyptians, Berbers — vastly outnumbered them. The caliphate solved this through a system that was extractive but not oppressive: conquered peoples paid taxes and accepted subordinate status, but kept their religions, languages, and local customs. Conversion to Islam brought equality (at least in theory), and over generations, most of the empire's population became Muslim. The Arab monopoly on power slowly dissolved, but the civilization they had created continued to flourish.
Islam was the organizing principle of Arab civilization. Five daily prayers structured time; the pilgrimage to Mecca connected scattered communities; Ramadan's fast unified the faithful in shared discipline. The Quran and the Prophet's example (sunna) provided guidance for every aspect of life, from commerce to marriage to warfare. Scholars elaborated these sources into comprehensive legal systems — the sharia — that governed the empire more effectively than any bureaucracy could.
The obligation of zakat — alms-giving — created a system of wealth redistribution that supported the poor, funded public works, and bound the community together through shared responsibility. Every Muslim with means contributed; every Muslim in need could receive. This was not charity in the voluntary sense but religious duty, enforced by social pressure and, in the caliphate, by state collection. The result was a society where extreme poverty was rarer than in contemporary Christendom, where widows and orphans had guaranteed support, and where wealth carried explicit obligations to the community that generated it.
The Arab caliphate sat at the center of the medieval world's trade networks. Baghdad, founded in 762 as the Abbasid capital, became the largest city on earth — perhaps a million inhabitants at its peak — where Persian administrators, Turkish soldiers, Indian mathematicians, and Greek philosophical texts translated into Arabic combined to create an intellectual golden age. Arab merchants sailed to China, traded in sub-Saharan Africa, and maintained commercial connections across Eurasia. The Arabic language became the Latin of the Islamic world: the tongue of scholarship, law, and high culture from Morocco to Malaysia.
By 945, when the Buyid dynasty seized control of Baghdad and reduced the caliph to a figurehead, the Arab moment of political dominance had passed. Persians, Turks, and Berbers would rule subsequent Islamic empires, though all claimed legitimacy through connection to Arab origins and the Prophet's legacy. But what the Arabs had created endured: a civilization defined by Islam, connected by Arabic, and stretching across the Old World. The caliphate's political unity shattered, but its cultural unity persisted for centuries — and in modified form, persists still.
In Glory of Civilizations, the Arabs represent a commercial civilization powered by faith. The bonus Market reflects how Arab conquest created vast trade networks where merchants moved freely across three continents. The coin payment for provinces followed by income from religious communities captures the zakat system — wealth flowing outward to support the faithful, then returning multiplied through the economic activity that shared prosperity generated.
Gaining coins whenever any player trades reflects Arab commercial dominance: their markets, their currency, their merchant networks profited from every transaction in the medieval world. Beginning with Theocracy and Islam represents the fusion of political and religious authority that defined the caliphate from its founding — no separation between mosque and state, no distinction between God's law and the ruler's.
Yes. The ability triggers when "any player trades" — including yourself. You gain 1 coin for each market the trading player has, and when you trade, you are that player.
Yes. You gain 1 coin for each of their markets, including any virtual markets they have from alliance abilities or other effects.
Nothing negative — you simply don't pay the coins you don't have. Then you gain 2 coins for each of your religious communities, and afterward you collect taxes normally. The payment is not a penalty; failing to pay doesn't harm you.
Yes. You already chose Theocracy and Islam as a free action before taking any regular actions. Your Reform action then lets you change one of these if you wish — you're not locked into your starting choices.
Yes. Your +1 Market counts as a real market for all purposes, including tax collection during the achievement phase.
