This chapter analyzes how the articulation of corporate sovereignty to capitalist value enabled corporations to transact business and enter into legal proceedings in multiple jurisdictions. It describes the coalescence of the pockmarked international regulatory structure for transnational corporations that emerged during the mid-20th century, and considers the ways legal frameworks of personhood were applied to corporations extraterritorially. The chapter also investigates the regulation of foreign corporations that emerged within the complex of territorial sovereignty, and examines the conflict of laws that concern trade disputes, nationalization of foreign corporate assets, and liabilities of corporations under public international law.
