ABSTRACT This paper explores the colonial history of the theory of ‘property-owning democracy.’ Focusing on R.R. Torrens’ title registration system, the paper links property-owning democracy to nineteenth-century debates on land rights and title registration. Instituted in South Australia in 1858, Torrens’ system linked the simplification of transactions in land to visions of a property-owning society. Seeking to replace complex land laws, Torrens’ system’s emphasis on speeding up land transactions appealed both to settler society and metropole. This transformation facilitated the dispossession of Indigenous lands and intertwined property law with colonial narratives of progress, liberty, and democracy. Ultimately, Torrens’ vision identified democracy with a new property regime securing the future of property title and political rights. Through a common engagement with nineteenth-century Britain’s ‘land question,’ Torrens’ project in South Australia is linked to the development of the twentieth-century political concept of property-owning democracy. The paper makes the case that exploring land registration debates reveals the importance of secure property rights and human capital in the history of ideas of property-owning democracy. Legal and bureaucratic innovations like the property register were considered to free individuals to invest in their own economic development and create the economic conditions for democracy.
