On this day 250 years ago in Philadelphia, the Continental Congress adopted the “Declaration of the Causes and Necessity of Taking Up Arms.” This Declaration was written by Thomas Jefferson and revised by John Dickinson and laid out the reasons for America taking up arms in rebellion against British rule of the colonies:

The legislature of Great Britain, . . . stimulated by an inordinate passion for a power, not only unjustifiable, but which they know to be peculiarly reprobated by the very constitution of that kingdom, . . . where regard should be had to truth, law, or right, have at length, deserting those, attempted to effect their cruel and impolitic purpose of enslaving these Colonies by violence, and have thereby rendered it necessary for us to close with their last appeal from Reason to Arms,-Yet, however blinded that assembly may be, by their intemperate rage for unlimited domination, so to slight justice and the opinion of mankind, we esteem ourselves bound, by obligations of respect to the rest of the world, to make known the justice of our cause.

Our forefathers, inhabitants of the island of Great Britain, left their native land, to seek on these shores a residence for civil and religious freedom. . . .

Parliament . . . have undertaken to give and grant our money without our consent, though we have ever exercised an exclusive right to dispose of our own property; statutes have been passed for extending the jurisdiction of courts of Admiralty and Vice-Admiralty beyond their ancient limits; for depriving us of the accustomed and inestimable privilege of trial by jury, in cases affecting both life and property; for suspending the legislature of one of the colonies: for interdicting all commerce to the capital of another; and for altering fundamentally the form of government established by charter, and secured by acts of its own legislature solemnly confirmed by the crown; for exempting the “murderers” of colonists from legal trial, and in effect, from punishment; for erecting in a neighboring province, acquired by the joint arms of Great Britain and America, a despotism dangerous to our very existence; and for quartering soldiers upon the colonists in time of profound peace. It has also been resolved in parliament, that colonists charged with committing certain offences, shall be transported to England to be tried.

But why should we enumerate our injuries in detail? By one statute it is declared, that parliament can “of right make laws to bind us IN ALL CASES WHATSOEVER.” What is to defend us against so enormous, so unlimited a power? Not a single man of those who assume it, is chosen by us; or is subject to our controul or influence; but, on the contrary, they are all of them exempt from the operation of such laws, . . . We for ten years incessantly and ineffectually besieged the Throne as supplicants; we reasoned, we remonstrated with parliament, in the most mild and decent language. But Administration, sensible that we should regard these oppressive measures as freemen ought to do, sent over fleets and armies to enforce them. The indignation of the Americans was roused, it is true; but it was the indignation of a virtuous, loyal, and affectionate people. A Congress of Delegates from the United Colonies was assembled at Philadelphia, on the fifth day of last September. We resolved again to offer an humble and dutiful petition to the King, and also addressed our fellow-subjects of Great Britain. We have pursued every temperate, every respectful measure: we have even proceeded to break off our commercial intercourse with our fellow-subjects, as the last peaceable admonition, that our attachment to no nation upon earth should supplant our attachment to liberty.-This, we flattered ourselves, was the ultimate step of the controversy: But subsequent events have shewn, how vain was this hope of finding moderation in our enemies.

. . . The Lords and Commons in their address, in the month of February, said, that “a rebellion at that time actually existed within the province of Massachusetts bay; and that those concerned in it, had been countenanced and encouraged by unlawful combinations and engagements, entered into by his Majesty’s subjects in several of the other colonies; and therefore they besought his Majesty, that he would take the most effectual measures to enforce due obedience to the laws and authority of the supreme legislature.”-Soon after, the commercial intercourse of whole colonies, with foreign countries, and with each other, was cut off by an act of Parliament; by another, several of them were entirely prohibited from the fisheries in the seas near their coasts, on which they always depended for their sustenance; and large re-inforcements of ships and troops were immediately sent over to General Gage.

. . .

Soon after the intelligence of these proceedings arrived on this continent, General Gage, who in the course of the last year had taken possession of the town of Boston, in the province of Massachusetts Bay, and still occupied it as a garrison, on the 19th day of April, sent out from that place a large detachment of his army, who made an unprovoked assault on the inhabitants of the said province, at the town of Lexington, as appears by the affidavits of a great number of persons, some of whom were officers and soldiers of that detachment, murdered eight of the inhabitants, and wounded many others. From thence the troops proceeded in warlike array to the town of Concord, where they set upon another party of the inhabitants of the same province, killing several and wounding more, until compelled to retreat by the country people suddenly assembled to repel this cruel aggression. Hostilities, thus commenced by the British troops, have been since prosecuted by them without regard to faith or reputation. . . .

. . .

We are reduced to the alternative of chusing an unconditional submission to the tyranny of irritated ministers, or resistance by force. . . . Honor, justice, and humanity, forbid us tamely to surrender that freedom which we received from our gallant ancestors, and which our innocent posterity have a right to receive from us. We cannot endure the infamy and guilt of resigning succeeding generations to that wretchedness which inevitably awaits them, if we basely entail hereditary bondage upon them.

Our cause is just. Our union is perfect. Our internal resources are great, and, if necessary, foreign assistance is undoubtedly attainable.-We . . . most solemnly, before God and the world, declare, that, exerting the utmost energy of those powers, which our beneficent Creator hath graciously bestowed upon us, the arms we have been compelled by our enemies to assume, we will, in defiance of every hazard, with unabating firmness and perseverance, employ for the preservation of our liberties; being with our mind resolved to dye Free-men rather than live Slaves.

. . .

In our own native land, in defence of the freedom that is our birth-right, and which we ever enjoyed till the late violation of it-for the protection of our property, acquired solely by the honest industry of our fore-fathers and ourselves, against violence actually offered, we have taken up arms. We shall lay them down when hostilities shall cease on the part of the aggressors, and all danger of their being renewed shall be removed, and not before.
