Indigenous and Postcolonial Critiques of Social Contract Justifications for Colonization (17th–20th centuries)

  1. Valladolid debate challenges conquest’s moral basis

    Labels: Valladolid Debate, Bartolom de

    Spanish officials convened a formal debate in Valladolid over whether Spain’s conquest and domination of Indigenous peoples in the Americas could be morally justified. Bartolomé de las Casas argued that Indigenous people were fully human and should not be enslaved or dispossessed. The debate did not end colonization, but it showed that European “justifications” for rule and land-taking were contested from within Europe early on.

  2. Grotius publishes Mare Liberum on trade rights

    Labels: Hugo Grotius, Mare Liberum

    Hugo Grotius published Mare Liberum (“The Free Seas”), arguing that no nation can own the high seas and that navigation and trade should be open to all. Although framed as a legal argument about freedom of the seas, it also served Dutch commercial and colonial expansion by opposing Iberian monopoly claims. It helped build an international-law vocabulary that could justify overseas access without Indigenous consent.

  3. Hobbes’s Leviathan popularizes contract-based sovereignty

    Labels: Thomas Hobbes, Leviathan

    Thomas Hobbes published Leviathan, arguing that people can create a sovereign through a “social contract” to escape violent insecurity. This strengthened a model of political legitimacy tied to a single, overriding authority. In colonial settings, similar ideas about who counts as “civil” and who can be ruled were often used to portray Indigenous governance as outside legitimate sovereignty.

  4. Locke’s Two Treatises links property to labor

    Labels: John Locke, Two Treatises

    John Locke’s Two Treatises of Government defended government by consent and developed a labor-based theory of property: mixing one’s labor with land can create ownership. Later readers and political actors used versions of this reasoning to claim that “unused” land could be appropriated—an idea that conflicted with many Indigenous land systems based on collective stewardship and long-standing use. Indigenous and postcolonial critics argue this helped normalize dispossession under a “rights” vocabulary.

  5. Rousseau critiques inequality and property’s origins

    Labels: Jean-Jacques Rousseau, Discourse on

    Jean-Jacques Rousseau’s Discourse on Inequality argued that social inequality grows with the rise of private property and social institutions that protect it. While not an Indigenous text, it offered a widely cited critique of property-based “civilization” stories used to justify conquest. Later anti-colonial writers drew on similar arguments to question whether “progress” narratives were covering up domination.

  6. Johnson v. M’Intosh codifies discovery-based land title

    Labels: Johnson v, U S

    The U.S. Supreme Court held in Johnson v. M’Intosh that European “discovery” gave the discovering nation exclusive title against other Europeans, while Indigenous nations retained a limited right of occupancy. This legal framework helped convert colonial conquest into domestic property law, narrowing Indigenous sovereignty and land rights in U.S. courts. Critics identify the case as a key example of how contract-and-property reasoning was used to legitimize dispossession.

  7. Treaty of Waitangi signed amid competing meanings

    Labels: Treaty of, M ori

    Representatives of the British Crown and many Māori rangatira (chiefs) signed Te Tiriti o Waitangi / the Treaty of Waitangi. It was presented as a basis for governance and protection, but differences between the Māori and English texts created lasting disagreement over whether sovereignty was ceded or shared. The treaty became a central site for Indigenous critiques of “consent” claims in settler governance.

  8. Native Land Act enables large-scale Māori land transfer

    Labels: Native Land, New Zealand

    New Zealand’s Native Land Act (commonly dated to 1862) changed land rules to make Māori land more easily converted into individual titles and sold. This shift weakened collective control and accelerated land loss, undermining any treaty-based idea of equal bargaining. It illustrates a pattern critics highlight: formal “legal” processes presented as voluntary exchange can operate under coercive conditions created by colonization.

  9. UN Charter adopts duties toward non-self-governing territories

    Labels: UN Charter, Non-self-governing Territories

    The United Nations Charter introduced an international commitment to promote the well-being and self-government of peoples in “non-self-governing territories.” This marked a major shift away from treating colonized territories as mere possessions of empires. It helped open space for postcolonial arguments that legitimate authority requires real self-determination, not imposed “consent.”

  10. Pateman’s Sexual Contract reframes contract theory’s exclusions

    Labels: Carole Pateman, The Sexual

    Carole Pateman’s The Sexual Contract argued that classic social contract stories often hide a deeper “contract” that normalizes patriarchy in modern civil society. Her critique influenced later work showing how contract language can erase unequal power relations and exclude whole groups from full citizenship. This framework became useful for analyzing how colonial states claimed legitimacy while subordinating Indigenous peoples.

  11. Mills’s Racial Contract links contract theory to domination

    Labels: Charles W, The Racial

    Charles W. Mills published The Racial Contract, arguing that what is often presented as a universal social contract has historically operated as a racialized agreement that privileges whites and dehumanizes nonwhite peoples. He connected modern political ideals to the practical realities of slavery, empire, and settler colonialism. The book helped systematize postcolonial and Indigenous-friendly critiques of “consent” narratives used to justify rule and extraction.

  12. Alfred argues for Indigenous self-determination beyond state “recognition”

    Labels: Taiaiake Alfred, Indigenous resurgence

    Taiaiake Alfred’s Peace, Power, Righteousness criticized state-centered frameworks that offer limited “recognition” while keeping colonial power intact. He urged Indigenous political resurgence grounded in Indigenous laws, responsibilities, and nationhood rather than assimilation into settler social-contract models. This work became influential in Indigenous political theory as a direct challenge to colonial legitimacy claims.

  13. UNDRIP adopted as global minimum standard for Indigenous rights

    Labels: UNDRIP, United Nations

    The UN General Assembly adopted the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP), setting out minimum standards for Indigenous survival, dignity, and well-being. Although not legally binding by itself, it strengthened global expectations around self-determination, land, culture, and participation in decisions affecting Indigenous peoples. It directly counters older colonial claims that Indigenous peoples lacked full political standing to consent or withhold consent.

  14. Waitangi Tribunal finds Treaty signatories did not cede sovereignty

    Labels: Waitangi Tribunal, Te Paparahi

    In a major finding from the Te Paparahi o Te Raki inquiry (Stage 1), the Waitangi Tribunal concluded that rangatira who signed Te Tiriti in February 1840 did not cede sovereignty to Britain. The Tribunal found that Māori agreed to a governor controlling British subjects while Māori would retain tino rangatiratanga (full chiefly authority). This outcome sharpened modern Indigenous critiques of colonial “social contract” claims based on disputed or uninformed consent.
