The Doctrine Of Discovery: Papal Bulls, Imperial Jurisprudence & The Dispossession Of Indigenous Peoples

1. Papal Origins of the Doctrine of Discovery

The Doctrine of Discovery originated in fifteenth-century papal bulls issued by the Vatican during the dawn of European maritime expansion.^[1] Papal decrees—most notably Dum Diversas (1452), Romanus Pontifex (1455), and Inter Caetera (1493) issued by Pope Alexander VI—commanded Christian European monarchs to invade, search out, capture, and subjugate all non-Christian peoples, seize their territories, and reduce their persons to perpetual servitude.^[2] Under this religious-legal framework, non-Christian Indigenous nations were stripped of legal sovereignty, their lands treated as vacant property available for the first Christian European explorer who planted a national flag.^[3]

2. Judicial Incorporation: Johnson v M'Intosh (1823)

During the nineteenth century, this theological doctrine was stripped of its explicitly religious language and integrated into secular international law by the United States Supreme Court.^[4] In the landmark decision Johnson v M'Intosh (1823), Chief Justice John Marshall ruled that European 'discovery' gave the discovering European sovereign exclusive title to the land against all other European powers, reducing Indigenous title to a mere 'right of occupancy' subject to unilateral state extinguishment.^[5] Marshall admitted that this doctrine was an arbitrary fiction derived from imperial power, but asserted that colonial conquest had become the accepted reality of international law.^[6]

3. Application to Western Australia and the Swan River Colony

British imperial authorities applied the core principles of the Doctrine of Discovery with ruthless consistency across Australia.^[7] Upon proclaiming the Swan River Colony in June 1829, Captain James Stirling operated on the premise that British naval discovery vested ultimate radical title in King George IV, completely extinguishing any independent sovereign imperium of the Bibbullmun people.^[8] Unlike in North America or New Zealand, where the British Crown negotiated formal land treaties with First Nations, in Western Australia the British refused even to recognise Aboriginal occupancy, executing complete territorial expropriation without a single penny of compensation.^[9]

4. Global Repudiation and the Decolonial Horizon

In March 2023, following decades of Indigenous advocacy, the Vatican issued an official joint statement formally repudiating the Doctrine of Discovery, admitting that papal bulls failed to recognise the inherent human rights of Indigenous peoples.^[10] International human rights bodies—including the United Nations Permanent Forum on Indigenous Issues—have called upon all common law states to purge the Doctrine of Discovery from their legal jurisprudence.^[11] In Australia, decolonising the law requires eliminating the vestigial remnants of Discovery, acknowledging Bibbullmun inherent title, and enacting genuine bilateral treaties.^[12]
