What was the Vatican's 2023 rescission of the Doctrine of Discovery?

On March 30, 2023 the Vatican's Dicastery for Culture and Education and Dicastery for Promoting Integral Human Development issued a joint statement formally repudiating the 15th-century papal bulls that had justified European colonisation and dispossession of Indigenous peoples. The principal documents repudiated were Inter Caetera (May 4, 1493, by Pope Alexander VI), Romanus Pontifex (January 8, 1455, by Pope Nicholas V), and Dum Diversas (June 18, 1452, also Pope Nicholas V). Together these documents formed the 'Doctrine of Discovery' that had underwritten European territorial claims in the Americas. The 2023 rescission responded to Truth and Reconciliation Commission Call to Action 49 and Indigenous lobbying.

The Doctrine of Discovery had been a foundation of European colonial law. The 1493 Inter Caetera bull divided non-Christian territories of the world between Spain and Portugal. The 1455 Romanus Pontifex authorised the Portuguese to enslave 'Saracens, pagans, and other enemies of Christ'. The 1452 Dum Diversas had similarly authorised slavery for non-Christian peoples. These bulls were used throughout the colonial era to justify European dispossession and enslavement of Indigenous peoples in the Americas, Africa, and elsewhere. The Doctrine shaped early Canadian common law, including the Royal Proclamation of 1763's framework for Indigenous land.

The Doctrine remained influential in modern law. The 1823 US Supreme Court case Johnson v. McIntosh had explicitly relied on the Doctrine in establishing American property law foundations. The Canadian common law had also drawn implicitly on the Doctrine, although the 1973 Calder, the 1990 Sparrow, the 1997 Delgamuukw, and the 2014 Tsilhqot'in Supreme Court of Canada decisions had progressively repudiated Doctrine-based reasoning in favour of recognising Indigenous land rights as flowing from Indigenous occupation. The 2023 Vatican rescission addressed the religious underpinnings, building on Pope Francis's April 2022 Vatican apology and his July 2022 Canadian apology for residential schools.

The 2023 statement explicitly stated: 'The Catholic Church therefore repudiates those concepts that fail to recognise the inherent human rights of Indigenous peoples, including what has become known as the legal and political doctrine of discovery'. Indigenous responses were mostly positive but noted that the rescission had come centuries after the harm and that specific actions (return of records, additional compensation, return of Indigenous artefacts held by Catholic institutions) would matter more than statements. TRC Call to Action 49 had called for repudiation of the Doctrine by all faith-based institutions; various Christian denominations have issued similar statements. The 2007 United Nations Declaration on the Rights of Indigenous Peoples (signed by Canada in 2010 and adopted as federal law in 2021) similarly affirms the rejection of doctrines premising Indigenous inferiority. The Doctrine of Discovery remains a topic of ongoing Indigenous and academic debate.
