The Declaration of Independence has become a lodestone for political morality. During the Revolution, enslaved people in New England seized on it to argue for abolition, as would Frederick Douglass and William Lloyd Garrison two generations later. Abraham Lincoln appealed to the Declaration, and politicians and statesmen have rallied to it for support in the years since. Americans even fancy our Declaration to be the root of other declarations of independence abroad. Greece, Belgium, New Zealand, Liberia, and Hungary all issued similar declarations in the 19th century. More recently, movements for independence cribbed from it in Europe (Czechoslovakia, Kosovo, Catalonia), Asia (Korea, Vietnam), Africa (Rhodesia, South Sudan), and the Middle East (Israel).
It is therefore natural to wonder who inspired something so inspirational as the Declaration. Academics have filled volumes debating the Declaration’s sources, and Barry Shain briefly surveyed them in an essential Liberty Fund collection. One of the most popular interpretations attributes the Declaration to Enlightenment-era assertions about rights and makes the Declaration appear quite radical. More conservative interpretations, however, emphasize republican and commonwealth notions of community and virtue, Protestant ideas about covenanting, or British constitutionalism in the Declaration.
Such readings have rightly been given their due, but in this Semiquincentennial year we must advance another motivation for the Declaration’s form and content: it is best understood as a model declaration of war.
Viewing the Declaration as a declaration of war enables us to appreciate it beyond its first two paragraphs, accounts for its international appeal, explains its conservative and radical elements, and respects the immense blood and treasure expended in a civil war that became a war for independence. North America was not plunged into terror and chaos merely for high ideals about liberty and equality or class interests. The Declaration was written to legally and morally defend a violent war and to assert the sovereignty of a new government. It was addressed not just to the king, to Americans, to Britons, or even to potential allies. It was addressed to the whole world in order to respect what we now call international law and just war theory.
The just war tradition extends back to the Hebrews, the Roman jus gentium, and medieval Christian scholastics, but to frame the Declaration as a declaration of war obliges revisiting the work of three essential natural law ethicists writing between the Treaty of Westphalia and the Founding: Hugo Grotius, Samuel Pufendorf, and Emer de Vattel. All three wrote substantial volumes providing nation-states with a science of law: also known as the droit des gens or law of nations. Vattel wrote closest to the time of the Founding and was widely read and cited by the Founders.
To Declare War is to Assert Sovereignty
Declaring war isn’t exclusive of declaring independence, of course. They overlap: to declare war was to declare independence for the Americans — not merely because the war (if won) would throw off British rule, but because to declare war presupposed sovereign status. According to international law, war generally ought to be waged by sovereign authorities or governments. Pufendorf, for example, calls war initiated by sovereigns solemn war. Vattel calls wars waged by sovereigns public war.
Of course, a sovereign declaring war had to acknowledge its moral responsibilities. Vattel connects the moral gravity of both sovereignty and warfare in a passage that surely hit home with Americans mindful not only of how George III had subjected them to violence, but how they were now subjecting one another to it under the authority of their new “sovereign” in Congress:
Whoever entertains a true idea of war, — whoever considers its terrible effects, its destructive and unhappy consequences, — will readily agree that it should never be undertaken without the most cogent reasons. Humanity revolts against a sovereign, who, without necessity or without very powerful reasons, lavishes the blood of his most faithful subjects, and exposes his people to the calamities of war, when he has it in his power to maintain them in the enjoyment of an honorable and salutary peace. And if to this imprudence, this want of love for his people, he moreover adds injustice towards those he attacks, — of how great a crime, or rather, of what a frightful series of crimes, does he not become guilty! . . . He is responsible to God, and accountable to human nature, for every individual that is killed, for every hut that is burned down.
Acknowledging moral responsibility for warfare requires that the just causes of the war are put into a declaration. Grotius elaborates on what he calls the “denunciation” or articulation of causes. Without denunciation (declaration), the state’s use of force is no better than that of pirates or robbers, a legal distinction extending back to the Romans. Vattel emphasizes that the declaration of war is not merely to justify the war to one’s citizens, or even to one’s enemies, but to all humanity. The published declaration of war is, he says, “at present the constant practice among the powers of Europe.” Hence, what Jefferson writes in the Declaration’s first paragraph about “a decent respect to the opinions of mankind requires that they should declare the causes” is not flowery verbiage. It reflected the diplomatic and moral norms expected of a lawful nation. Congress would not be taken seriously as a new sovereign power without a morally defensible declaration of war.
Likewise, the “religious” language of the Declaration, found at its beginning and end, reflected what was necessary for asserting the right of declaring war and adhering to legal norms. According to the law of nations, Americans could assume “among the powers of the earth” their “separate and equal station” only according to the “Laws of Nature and of Nature’s God.” This phrase was a framework for sovereignty in the existing template set forth in Vattel and his predecessors, and not some pious or philosophical jaunt to be parsed by twentieth-century academics determining which flavor of deist or theist Jefferson was. Rather, according to Grotius, the appeal to God was customary in declarations/denunciations. As Grotius quoted it in the Roman case, “I call the Gods to Witness that Nation is unjust, and will not render what is right.” This is what he calls the “usual Form” of denunciation or declaration.
The aggrieved nation appeals to divine justice because nations, as nations, have no other authoritative judge to whom they can appeal their cause. Vattel writes that a declaration of war presents its catalog of “miseries and crimes . . . to the king of kings.” Hence, the Americans not only begin by invoking God but also end their Declaration by asserting their right to “full Power to levy War, conclude Peace, contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do” and immediately after that declare their “firm reliance on the protection of divine Providence.” In short, asserting rights of sovereignty, including war, is always done with an eye to moral obligations or responsibilities, and the final arbiter of their fulfillment in the case of nations is God alone.
Responsibilities of Sovereignty and the Betrayal of Sovereignty
Further elaborating the moral and legal responsibilities of sovereignty furnishes much of the rest of the document. The motivation is twofold. First, insofar as the King failed in his responsibilities as a sovereign, war to replace his reign in America was justified. Natural law (including jurisprudential reasoning) understood that sovereigns who abandon their responsibilities are guilty of moral and legal offenses voiding the allegiance owed by citizens. Second, the new sovereign (Congress) must acknowledge its obligations as a sovereign. To see these motivations clearly ought to inhibit the American habit of amputating philosophically pleasing passages of the Declaration and grafting them to circumstances of our choosing. It is more in keeping with the Declaration’s intent to root its political and philosophical claims in the legal and political soil of sovereignty and just warfare.
Such proper rooting is especially important for Jefferson’s claim of rights to life, liberty, and the pursuit of happiness, however many oceans of ink have been expended to riff on them. Jefferson is merely reflecting the natural law ethicists and the language of sovereignty. Sovereign authority, Vattel writes, exists only for the “preservation and perfection” of the nation and its citizens. The first of these concepts, preservation, is the basis of Jefferson’s appeal to life. Vattel argues that the first object of a nation (and sovereign) is an economic necessity to sustain productivity, including labor and industry, agriculture, foreign and domestic trade, infrastructure, money, and commercial law which all enable and sustain human life. Vattel is not purely laissez faire; he allows for many elements of modern public policy including encouragement of certain professions, tariffs, taxes, monopolies, restrictions on emigration and imports, and creation of public property, for example. But he also emphasizes that liberty to trade is not simply the right of individuals but of nations as well. Both reflect the law of nature. Therefore, when the commercial and property rights of the colonists were not respected by George III, the people had a just case for war. Violations enumerated in the Declaration include restrictions on population (labor) and land use, imposition of unjust taxes and regulations, cutting off trade, and destruction of property. These violations all undermined what Vattel considers the primary goal of being a sovereign nation, the preservation of its people.
Life and liberty aren’t confined by Vattel to purely material or economic purposes, however. Citizens in a sovereign nation pursue perfection as well, which is Vattel’s second function of government. What does perfection mean? The answer is found in the third part of Jefferson’s triad: happiness. Happiness was not a word without clear definition in the eighteenth century. Vattel mentions happiness or felicity dozens of times, especially in his elucidation of perfection. True happiness is enabled, he argues, by education (including free discussion), virtue, piety, and religion (including liberty of conscience). But justice (including distributive justice) and law are especially important for perfection. Knowing that enables better understanding of the significance of the Declaration’s grievances: the king forbade the making of laws, harassed or dissolved colonial legislatures, disabled justice through martial law, prevented establishment of judiciary powers, compromised the integrity of judges, abridged the right to jury trial, and subjected the colonists to legal authority they did not consent to (Parliament) as well as to courts in foreign venues. Perfection was even potentially unjustly abridged by the Quebec Act of 1774 (obliquely referenced as “abolishing the free System of English Laws in a neighboring province”) insofar as this would have established Roman Catholicism along American borders — something that the overwhelmingly Protestant colonists at that time considered a threat to true religion and to the rule of law.
War as Last Resort
Having seen how the rights and responsibilities of sovereignty account for most of the language of the Declaration, we can now turn to its language about war as a last resort. Such language accounts for the remainder of the text, beginning in the second paragraph (“Whenever any Form of Government…”) and resuming in the second and third-to-last paragraphs (“In every stage of these oppressions we have petitioned for redress…”). Defending the recourse to war was an essential part of the existing legal and moral template for declarations of war, and understandably so because of its destructive nature. All nonviolent means had to be exhausted first. As Jefferson says, “Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes.”
Of course, public safety is a very “just and weighty reason” for warfare (as Vattel calls it), and Jefferson clearly indicts the king for direct attacks on life and property; but tyranny threatens the civil order just as much as war, and Jefferson indicts it even before he condemns the physical destruction. The definition of tyranny for early modern natural law theorists was still quite classical: tyranny is the use of sovereign power and abuse of fundamental laws for any purpose other than the “happiness of all the people,” By fundamental laws, Vattel means the nation’s constitution, which he calls the “foundation of public tranquility.” Constitutional arguments made by the Americans since the Stamp Act Crisis therefore made a decade-long case that they were the victims of tyranny and prepared a decade-long legal brief for war.
When a previously legal sovereign becomes a tyrant (as Philip II did in the Netherlands, Vattel argues), he then “commands without right” and the nation is not only free to disobey him, but to resist him. Under conditions of extreme necessity, the tyrant even becomes a public enemy who may be killed. Self-defense is thus extended beyond the defense of one’s life (preservation) to the preservation of rights (perfection). Tyranny releases the citizens from their responsibilities. “This truth,” Vattel says, “is acknowledged by every sensible writer.” Absolute rule is so dangerous that it may even eclipse the danger of civil war. And after all, Vattel argues, (in one of several passages informing Jefferson’s own “laws of nature and nature’s God,”) blind obedience to any sovereign would violate the “laws of nature” and “sacred law.”
Of course, the determination of tyranny and subsequent assertion of right against it are no small matter and require great care. First, the designation of a public enemy is a judgment that Vattel says “can only be passed by the nation, or by a body which represents it.” This, of course,was Congress in the American case. Second, one cannot make war before every other recourse is explored first. As Vattel writes, “Force is a wretched and melancholy expedient against those who spurn at justice and refuse to listen to the remonstrances of reason.” These remonstrances are essential because a sovereign’s refusal to address them makes self-defense imperative. Such application for justice, what Vattel called “a conditional declaration of war,” was already provided in 1775 and reflected many prior “just causes of complaint.”
By 1776, however, it had become apparent, as Jefferson wrote, that a “long train of abuses” was the answer to their appeals instead. War becomes necessary, Vattel says, when “the people can no longer view” a sovereign “but as an usurper who would load them with oppression.” Under such conditions, Vattel says (in a passage preceding Jefferson’s own almost verbatim) self-defense is “not only the right but the duty of a nation.” Vattel even calls it a “sacred duty.” Those who “do not stretch out their necks to the yoke of slavery . . . to crouch under the rod of arbitrary power” may be called rebels by their (unjust sovereign), but the integrity of an opposing faction creates a civil war rather than a mere rebellion. Reiterating the theme of divine justice, Vattel argues that civil war is like a contest between two nations: on earth they have no common superior and must appeal to God.
Recommitting Ourselves
To acknowledge the Declaration’s dependence on an existing legal framework should in no way diminish our appreciation for its eloquence and brilliance. But to presume that its eloquence or brilliance built something wholly new is to forget that America is subject to the ethical obligations owed by all sovereign nations. The men who signed the Declaration knew and acknowledged those obligations, and in this anniversary year of their great achievement signed more with blood than with ink, we should renew our own commitment to America’s preservation and perfection.
