In 1452 Pope Nicholas V issued a bull called Dum Diversas. It authorised the King of Portugal to invade, capture and subdue "all Saracens and pagans whatsoever", to take their lands and goods, and to reduce their persons to perpetual slavery.
Read the list of targets again. Saracens come first.
This was the moment Europe's machine left home. For centuries it had been refined on minorities inside Europe: heretics, Jews, the Irish. Now a single document gave it permission to operate everywhere on earth, with a theological warrant. If Christianity was the only truth, non-Christian peoples had no real claim to land, sovereignty or freedom. Their lands were, in effect, vacant. Their persons were available.
In 1493, after Columbus, another bull drew a line through the Atlantic and divided the non-Christian world between Spain and Portugal. Continents neither had seen, and tens of millions of people, were allocated by one man in Rome.
Theology and money were fused from the start. The bulls were requested by the crowns that wanted legal cover for the slave trade, the spice trade and the gold. Ideology supplied the justification. Economics supplied the motive. The machine turned both into action.
We like to think this is medieval history. It is not.
The Doctrine of Discovery was built into the law of the United States, Canada, Australia and New Zealand. In 1823 the US Supreme Court relied on it to rule that "discovery" gave European nations title to indigenous land. That ruling has never been overturned. The Vatican only repudiated the Doctrine in 2023, and even then said the bulls had been "manipulated", as if documents that explicitly authorised enslavement had been neutral tools misused.
And the assumption behind it has never left. When a European politician says Muslims must accept European values, the premise goes unspoken: those values are a higher stage of human development, and whoever does not share them is deficient. Nobody argues this. It is simply assumed, the way air is assumed.
Here is what that means for Muslims in Europe.
When our parents and grandparents arrived in the twentieth century, the machine did not need to be recalibrated for them. It did not need to learn who they were. The classification had been issued five centuries earlier, secularised since then from the language of Christendom into the language of civilisation and modernity, but never withdrawn.
We were classified before we were born, by a document most Europeans have never heard of.
I breathe that air. So do my children. It is not history. It is atmosphere.
And you cannot argue with the air. You can only learn to see it.
