Q:
“Do we have a period in history without conflicts and wars before 1400 yrs? Share, if not then why and who was always on the wrong side, followers of which faith were on the wrong side?”

A:

🔴 Part 1: Has There Ever Been a Period Without War?
The short answer: No — not a single extended era of true global peace exists in the human record.
Although many have sought to understand why wars occur and find peaceful solutions, wars have continued to plague humankind into the twenty-first century. Even when weapons capable of destroying all life on earth were invented, wars did not cease. No matter how many dead or injured return, or how many people say there should never be another war, another war has always erupted. 
The earliest conflicts were likely small-scale, involving tribal groups competing for resources, laying the groundwork for more organized forms of warfare as populations grew and societies became more complex.  The Battle of Hamoukar (~3500 BCE) is among the earliest archaeological evidence of organized warfare between city-states.

🔴 Part 2: A Survey of Perpetual Conflict Before Islam (Pre-610 CE)
⚔️ Mesopotamia & Ancient Near East
The Assyrian Empire (934–609 BCE) is historically notorious for systematic campaigns of mass displacement, torture, and terror as deliberate state policy to subdue conquered peoples — cruelty documented even in their own royal inscriptions. The Babylonians, Egyptians, Hittites, and others engaged in centuries of conquest and counter-conquest.
⚔️ The Greco-Macedonian World
Alexander the Great’s wars of conquest began with the Achaemenid Empire and extended from Greece to the Indus Valley, spanning Anatolia, Syria, Phoenicia, Egypt, Mesopotamia, Greater Iran, Afghanistan, and India. 
This was empire-building through pure military force across millions of square miles, displacing entire civilizations under Hellenistic domination.
⚔️ Rome vs. Persia — 700 Years of Continuous War
This is perhaps the most dramatic example:
The Roman-Persian Wars spanned 700 years, encompassing the late Roman Republic, the Roman Empire, and the Byzantine Empire in the west, and the Parthian and Sassanid Empires in the east. In spite of years of conflict and dozens of campaigns, nothing of long-term significance resulted — the border between the empires remained roughly the same for most of the period. 
Their involvement was driven by economic greed and the desire to represent the single most dominant military and political power in the ancient world. 
Seven centuries of bloodshed — for nothing. No justice, no liberation, no moral framework — just imperial rivalry and ambition.
The Parthians had done nothing to justify Crassus’ invasion.  Rome simply wanted more.
By the time Islam appeared:
It was at this juncture that Islam appeared outside Arabia as the “rightly guided caliphs” led the new Muslim armies out of Arabia at the very moment that Persia, having been defeated, and Byzantium, victorious but exhausted, could hardly defend themselves. 
Neither empire was given any chance to recover, as within a few years they were struck by the onslaught of the Arabs, newly united by Islam. 

🔴 Part 3: Who Was “On the Wrong Side”?
This is where the question requires intellectual honesty and a layered answer — because it cannot be reduced to a single faith identity across all eras.
📌 The Framework from an Islamic Lens
The Qur’an does not frame human history as “believers vs. disbelievers” in simple tribal terms. It frames it as ’adl (justice) vs. zulm (oppression) — and empires, regardless of their religious label, fell based on this moral criterion.
Allah says (Surah Al-An’am 6:131):
“This is because your Lord would not destroy the cities unjustly while their people are unaware.”
And (Surah Al-Isra 17:16):
“When We decide to destroy a city, We command those given to luxury [to reform], but they persist in sin, and so the word [of doom] is justified against them, and We destroy them utterly.”
So the Sunnatullah (Divine Law in history) is clear: nations are destroyed not for their ethnicity or nominal faith label, but for their moral corruption, oppression, and arrogance.
📌 Who Drove the Pre-Islamic Wars?
Looking at the historical record before 1400 years ago (i.e., before ~622 CE): Power Dominant Religion Pattern Roman/Byzantine Empire Paganism → Christianity Imperial conquest, gladiatorial slavery, massacre of Prophets’ followers Sassanid Persian Empire Zoroastrianism 700 years of aggressive wars, persecution of Christians and minorities Assyrian Empire Polytheism Systematic terror and mass deportation Macedonian/Greek Empire Polytheism/Philosophy Military conquest across three continents Pre-Islamic Arabia Polytheism/Tribalism Perpetual tribal warfare, infanticide, slavery

Key observation: The overwhelming pattern of systemic, organized injustice in the pre-Islamic world came overwhelmingly from:
1. Polytheistic imperial systems — Rome, Greece, Assyria, Persia (Zoroastrian) — rooted in no divine moral accountability structure.
2. Corrupted monotheism — The Christianity of the Byzantine Empire by the 4th–6th centuries had become deeply entangled with imperial politics, persecuting Jews, heretics, and dissidents; launching religious wars; and institutionalizing class oppression. This was far removed from the teachings of ’Isa (عليه السلام).
However — a critical Islamic clarification: The Qur’an is careful. It does not condemn “Christians” or “Zoroastrians” as peoples. It condemns systems of power built on arrogance and oppression, regardless of the banner they carry. The Qur’an even praises the Byzantine victory (Surah Ar-Rum 30:2–4) as something the believers hoped for — because at that moment, the People of the Book (even in their corrupt state) were seen as preferable to the fire-worshipping Sassanids.
📌 The Deeper Islamic Answer
The Qur’an’s diagnosis of pre-Islamic humanity is not primarily about which faith — it is about ghaflah (heedlessness) and kibr (arrogance):
“Corruption has appeared on land and sea because of what people’s hands have earned.” (Ar-Rum 30:41)
Before Islam, there was no civilization with a comprehensive, divinely revealed system simultaneously governing justice, law, economics, warfare ethics, women’s rights, and international relations. What existed were fragments — some wisdom in Zoroastrianism, some in Greek philosophy, some in remnant monotheism — but no complete Deen organizing society on tawheed.
That is the Islamic answer to why there was perpetual conflict: the absence of a divinely anchored moral-legal civilization that could unite humanity across tribal, ethnic, and national lines.

🔴 Conclusion: The Islamic Perspective on History
From a Qur’anic framework, history before Islam can be summarized in three layers:

1. Universal human weakness (nafs ammara bis-soo’) — all humans without revelation tend toward greed, tribalism, and power.
2. Corrupt or absent revelation — the teachings of Musa and ’Isa (عليهم السلام) had been distorted or lost in their original purity, leaving civilizations without a living divine standard.
3. The structural role of Islam — when the Prophet ﷺ came, he didn’t just bring theology. He brought a civilization-restructuring system — abolishing tribal warfare, regulating warfare with rules of engagement (no killing civilians, no cutting trees, no mutilation), replacing blood feuds with law, and grounding justice in divine authority rather than imperial will.
   The Sahaba witnessed two superpowers destroying each other and tens of millions of people dying in 700 years of pointless war — then Islam came and, within a generation, brought those very same peoples into one Ummah of justice and faith.
   As Allah (سبحانه وتعالى) says:
   “And We have not sent you [O Muhammad] except as a mercy for all the worlds.” (Al-Anbiya 21:107)
