TheCommentaries on the Laws of England[1] (commonly, but informally known asBlackstone's Commentaries) are an influential 18th-centurytreatise on thecommon law of England by SirWilliam Blackstone, originally published by theClarendon Press atOxford between 1765 and 1769. The work is divided into four volumes, on the rights of persons, the rights of things, of private wrongs and of public wrongs.
TheCommentaries were long regarded as the leading work on the development of English law and played a role in the development of theAmerican legal system. They were in fact the first methodical treatise on the common law suitable for a lay readership since at least theMiddle Ages. The common law of England has relied onprecedent more thanstatute and codifications and has been far less amenable than thecivil law, developed from theRoman law, to the needs of a treatise. TheCommentaries were influential largely because they were in fact readable, and because they met a need. As such, they were used in the training of American and British lawyers long after the death of Blackstone.
TheCommentaries are often quoted as the definitive pre-Revolutionary source of common law byUnited States courts.[citation needed]Opinions of theSupreme Court of the United States quote from Blackstone's work whenever they wish to engage in historical discussion that goes back that far, or farther (for example, when discussing the intent of theFramers of the Constitution). The book was famously used as the key inBenedict Arnold'sArnold cipher, which he used to communicate secretly with his conspiratorJohn André during their plot to betray theContinental Army during theAmerican Revolution.
In 1765 Blackstone announced his resignation from theVinerian Chair, effective after his 1766 lectures. These were divided into two 14-lecture series, on "private wrongs" and "public wrongs" delivered between 12 February and 24 April.[2] At this point Blackstone had published nothing new sinceA Treatise on the Law of Descents in Fee Simple in 1759.[3] The decision to resign was most likely due to the increasing demands of his legal practice and the reduced profit from the lectures, which, after peaking at £340 in 1762, dropped to £239 a year later and to £203 for the final round of lectures in 1765–66.[4]
In response, Blackstone decided to publish a new bookCommentaries on the Laws of England. The first volume was published in November 1765, bringing the author £1,600; the full work would eventually bring in over £14,000.Owen Ruffhead described Volume I as "masterly", noting that "Mr Blackstone is perhaps the first who has treated the body of the law in a liberal, elegant and constitutional manner. A vein of good sense and moderation runs through every page". Every copy was sold within six months, and the second and third volumes, published in October 1766 and June 1768, received a similar reception.[5] The fourth and final volume appeared in 1769, dealing with criminal law.[6] With the financial success of theCommentaries, Blackstone moved in 1768 from his London property in Carey Fields to No. 55 Lincoln's Inn Fields. Neighbours included theSardinian ambassador,Sir Walter Rawlinson,Lord Northington,John Morton and theThird Earl of Abingdon, making it an appropriate house for a "great and able Lawyer".[7]
Blackstone's treatise was republished in 1770, 1773, 1774, 1775, 1778 and in a posthumous edition in 1783.[8] Reprints of the first edition, intended for practical use rather than antiquary interest, were published until the 1870s in England and Wales, and a working version byHenry John Stephen, first published in 1841,[9] was reprinted until after theSecond World War.[10] The first American edition was produced in 1772; prior to this, over 1,000 copies had already been sold in theThirteen Colonies.[11]

The Rights of Persons is the first volume in the four part series that is the Commentaries. Divided into 18 chapters, it is largely concerned with the rights of individuals; the rights ofParliament; the rights and title of theKing; theroyal family; the councils belonging to the King; kingly duties; theroyal prerogative; the King's revenue; subordinate magistrates; the people (aliens, denizens, and natives); the rights of the clergy; the civil state; the military and maritime states; the relationship between master and servant (in modern-day terminology,employer andemployee), husband and wife, parent and child,guardian andward; and finally corporates.
The Rights of Things, Blackstone's longest volume, deals withproperty. The vast majority of the text is devoted toreal property, this being the most valuable sort in thefeudal law upon which the English law of land was founded. Property inchattels was already beginning to overshadow property in land, but its law lacked the complex feudal background of the common law of land, and was not dealt with nearly as extensively by Blackstone.
Of Private Wrongs dealt withtorts as they existed in Blackstone's time. The various methods oftrial that existed at civil law were also dealt with in this volume, as were the jurisdictions of the several courts, from the lowest to the highest. Almost as an afterthought, Blackstone also adds a brief chapter onequity, the parallel legal system that existed in English law at the time, seeking to address wrongs that the common law did not handle.
Of Public Wrongs is Blackstone's treatise oncriminal law. Here, Blackstone seeks to explain how the criminal laws of England were just and merciful, despite becoming later known as theBloody Code for their severity. He does however accept that "It is a melancholy truth, that among the variety of actions which men are daily liable to commit, no less than an hundred and sixty have been declared by Act of Parliament to be felonious withoutbenefit of clergy; or, in other words, to be worthy of instant death". Blackstone frequently resorted to assuring his reader that the laws as written were not always enforced, and that the King's power ofpardon could be exercised to correct any hardships or injustices.
Blackstone for the first time made thecommon law readable and understandable by non-lawyers. At first, hisCommentaries were hotly contested, some seeing in them an evil or covert attempt to reduce orcodify the common law which was anathema to common law purists.[citation needed]
For decades, a study of theCommentaries was required reading for all first year law students.Lord Avonmore said of Blackstone: "He it was who first gave to the law the air of a science. He found it a skeleton and clothed it with life, colour and complexion. He embraced the cold statue and by his touch, it grew into youth, health and beauty."Jeremy Bentham, who had been a critic of theCommentaries when they were first published, credits Blackstone with having "taught jurisprudence to speak the language of the scholar and the gentleman; put a polish upon that rugged science, cleansed her from the dust and cobwebs of the office and, if he has not enriched her with that precision which is drawn only from the sterling treasury of the sciences, has decked her out to advantage from thetoilet of classical erudition, enlivened her with metaphors and allusions and sent her abroad in some measure to instruct."[12]
While there is much valuable historical information in theCommentaries, later historians have tended to be somewhat critical of the uses Blackstone made ofhistory.There is a lot of what would later be called "Whig history" in theCommentaries:[citation needed] the easy and contradictory assurance that England's current political settlement represented the optimal state of rational and just government, while claiming simultaneously that this optimal state was an ideal that had always existed in the past, despite the many struggles in England's history between overreaching kings and wayward parliaments.
But Blackstone's chief contribution was to create a succinct, readable, and above allhandy epitome of the common law tradition. Whileuseful in England, Blackstone's text answered an urgent need in the developing United States and Canada.[citation needed] In the United States, the common law tradition was being spread into frontier areas, but it was not feasible forlawyers andjudges to carry around the large libraries that contained the common lawprecedents.[citation needed] The four volumes of Blackstone put the gist of that tradition in portable form. (A modern paperback printing of the four volumes total about 1500 pages.[13]) They were required reading for most lawyers in the Colonies, and for many, they were the only reading.[citation needed]Blackstone'sWhiggish butconservative vision of English law as a force to protect people, theirliberty, and their property, had a deep impact on theideologies that were cited in support of theAmerican Revolution, and ultimately, theUnited States Constitution.[citation needed]
Two decades after their publication, Blackstone'sCommentaries were the focus of a mocking polemic byJeremy Bentham, calledFragment on Government.[14] This dissection of Blackstone's first book made Bentham's name notorious, though it was originally published anonymously.[citation needed]
In 1841–1845,Henry John Stephen publishedNew Commentaries on the Laws of England (Partly Founded on Blackstone), whose structure was modelled on Blackstone's work and which liberally quoted from it; much of Blackstone's text remained as late as 1914 in the 16th edition ofStephen's Commentaries; in 1922 underEdward Jenks most of the text was rewritten but the structure was realigned more closely to Blackstone's original.[15][16]
Of great importance to the public is the preservation of this personal liberty; for if once it were left in the power of any the highest magistrate to imprison arbitrarily whomever he or his officers thought proper, (as in France it is daily practised by the crown,) there would soon be an end of all other rights and immunities. Some have thought that unjust attacks, even upon life or property, at the arbitrary will of the magistrate, are less dangerous to the commonwealth than such as are made upon the personal liberty of the subject. To bereave a man of life, or by violence to confiscate his estate, without accusation or trial, would be so gross and notorious an act of despotism, as must at once convey the alarm of tyranny throughout the whole kingdom; but confinement of the person, by secretly hurrying him to jail, where his sufferings are unknown or forgotten, is a less public, a less striking, and therefore a more dangerous engine of arbitrary government.[17]
[T]he principal aim of society is to protect individuals in the enjoyment of those absolute rights, which were vested in them by the immutable laws of nature, but which could not be preserved in peace without that mutual assistance and intercourse which is gained by the institution of friendly and social communities. Hence it follows, that the first and primary end of human laws is to maintain and regulate these absolute rights of individuals.[17]
Thatthe King can do no wrong, is a necessary and fundamental principle of the English constitution.[18]
It is better that ten guilty persons escape than one innocent suffer.[19]
There is nothing which so generally strikes the imagination, and engages the affections of mankind, as the right ofproperty; or that sole and despotic dominion which one man claims and exercises over the external things of the world, in total exclusion of the right of any other individual in the universe. And yet there are very few, that will give themselves the trouble to consider the original and foundation of this right.[20]
