Situating Enlightenment theories of rights in a broader arc extending back to the Scientific Revolution, this chapter focuses on the Italian jurists and philosophers who incorporated these theories into constitutional thought. Drawing on the works of Montesquieu and Rousseau, in particular, Gaetano Filangieri sought to reformulate arguments about natural rights in terms of a legislative “science.” This science, which would be eagerly received across Europe and Spanish America, sought to incorporate rights and popular sovereignty into constitutional law. Filangieri also drew on Italian intellectual traditions, which (in the case of Antonio Genovesi) insisted on social, alongside individual, rights. Following the influential example of Cesare Beccaria, Filangieri also paid particular attention to rights in penal matters. His constitutional principles were poignantly, if briefly, embodied in the 1799 Constitution of the Neapolitan Republic, drafted by Francesco Pagano.

This chapter traces the history of the world's anti-death penalty movement, noting how countries moved away from punishments such as breaking on the wheel and burning at the stake and how capital punishment has been abolished or curtailed in various countries and American states. After taking note of early successes of the abolitionist movement, the chapter discusses abolitionist efforts over time, including in the Progressive Era and in the post-World War II period (e.g., in Europe and the Americas). In particular, the chapter discusses American states (i.e., Michigan, Wisconsin and Rhode Island) that abolished capital punishment before the American Civil War, and describes how West Germany outlawed capital punishment in its constitution in 1949. The chapter discusses how international human rights law has evolved in the post-World War II period, with capital punishment coming under increased scrutiny and protocols to international and regional human rights conventions (e.g., the Second Optional Protocol to the International Covenant on Civil and Political Rights, Protocols 6 & 13 to the European Convention on Human Rights) abolishing or restricting the death penalty's use.

This chapter notes how ancient societies used capital punishment, highlighting methods of execution and various legal codes (e.g., Draco's Code and the Code of Hammurabi) authorizing executions. The chapter discusses the "divine right of kings," corporal punishments used in prior centuries, and the lex talionis doctrine. It also highlights how punishment practices were tied to religious and societial beliefs, including interpretation of religious texts. The chapter traces the change in the law from the Dark Ages to the Enlightenment, taking note of how judicial torture--a practice associated with contintental European civil law systems--was outlawed in certain locales in the eighteenth century even as harsh systems of punishment (e.g., the English "Bloody Code") persisted. The chapter also describes the Enlightenment thinkers--John Bellers, George Fox, William Penn, Voltaire, Montesquieu, Frederick II, Cesare Beccaria, and William Blackstone--who critiqued torture and capital punishment or called for the death penalty's abolition or curtailment. The chapter describes the death penalty's abolition in Tuscany (1786) and Austria (1787) and how the Enlightenment shaped the law.
