The idea which still floats vaguely in many minds that Ireland, before the arrival of the Normans, was a single and independent nation, is wholly false. Ireland was not a nation, but a collection of separate tribes and kingdoms, engaged in almost constant warfare. In this respect, however, she resembled many countries which have since attained the most perfect unity, and there can be little doubt that, if her development had been impeded by no extraneous influences, Ireland would have followed the same path as England or France. Much stress has been justly laid on the disorganising influence of a long succession of Danish invasions, though it must be remembered that Ireland owes to the Danes the foundation of some of her most important cities. Roman conquest, which introduced into most of Europe invaluable elements of order, organisation, and respect for law, never extended to Ireland. The Anglo-Norman invasion and conquest produced consequences which were almost wholly evil. If the invaders had been driven from the Irish shore, the natural course of development would, no doubt, have been in time continued. If the invaders had completely conquered Ireland, a fusion might have taken place as complete and as healthy as in England. Neither of these two events occurred. The English conquest was prolonged over nearly four hundred years. A hostile and separate power was planted in the centre of Ireland sufficiently powerful to prevent the formation of another civilisation, yet not sufficiently powerful to impose a civilisation of its own. Feudalism was introduced, but the keystone of the system, a strong resident sovereign, was wanting, and Ireland was soon torn by the wars of great Anglo-Norman nobles, who were, in fact, independent sovereigns, much like the old Irish kings. The Scotch invasion of the fourteenth century added enormously to the anarchy and confusion; the English power as a living reality contracted to the narrow limits of the pale; in outlying districts the Anglo-Norman assimilated quickly with the Celtic element, while the English legislators in Ireland, alarmed at the tendency, made it the main object of their policy, in the words of Sir John Davies, 'to make a perpetual separation and enmity between the English and Irish, pretending no doubt that the English should in the end root out the Irish.'

Such a state of things continued till the long and terrible wars of Henry VIII. and Elizabeth broke the power of the independent chiefs and of the Celtic clans, and gave Ireland, for the first time, a political unity. It is one of the great infelicities of Irish history that this result was obtained at the very period of the Reformation. The conquerors adopted one religion, while the conquered retained the other, and thus a new and most enduring barrier was raised between the two nations in Ireland, and a pernicious antagonism was established between law and religion.

Another influence not less powerful than religion had at the same time come into play. It had become the English policy to place great bodies of English and Scotch settlers on the land that was confiscated in consequence of rebellion, and under the impulse of the strong spirit of adventure which grew up in the generation that followed the Reformation, streams of English and Scotch adventurers poured over. The great settlement of Ulster under James I. proved ultimately a success, and laid the foundation of the prosperity of that province. Other plantations were in time absorbed and assimilated by the Celtic population; but vast revolutions in the ownership of land, accompanied by the subversion of the old tribal customs, laid the foundation of an agrarian war which still continues.

Religious and agrarian causes combined with the civil war in England to produce the great rebellion of 1641 and the eleven years of ghastly, exterminating war which followed. Hardly any page in human history is more appalling. A full third of the population of Ireland perished. Thirty or forty thousand of the most energetic left the country and took service in foreign armies. Great tracts were left absolutely depopulated, and after the rearrangement of land, which was accomplished by the Act of Settlement, the immense preponderance of landed property remained in the hands of the Protestant nation.

New elements, however, of great energy had been planted in Ireland, and the field had been thrown open to their exertions. The excellence of Irish wool and the cheapness of Irish labour laid the foundation of a flourishing woollen manufacture, and with peace, mild administration, and much practical tolerance, the wounds of the country seemed gradually healing. The later Stuart reigns, which form a dark page in English history, were a period of considerable prosperity in Ireland, but that period was soon interrupted by the Revolution. There was no general or passionate rising in Ireland resembling that of 1641, but it was inevitable that the Irish Catholics should have adopted the side of the Catholic King, and it was equally inevitable that when a Catholic Parliament, consisting largely of sons of the men whose properties had recently been confiscated, had assembled at Dublin, its members should have made a desperate effort to reverse their fortunes and replace the land of the country mainly in Catholic hands. The battle of the Boyne shattered the Catholic hopes, and it was followed by a new confiscation, by a new emigration of the ablest and most energetic Catholics, by a long period of commercial restraints, penal laws, and complete Protestant ascendancy.

The commercial restraints formed part of a protective policy which was at that time general in Europe, and which was severely felt in the American colonies. Though it did not absolutely originate in, it was greatly intensified by, the Revolution, which gave the manufacturing and commercial classes a new power in English government. The linen manufacture was spared, but the total destruction by law of the flourishing woollen manufacture, followed by a number of restrictions imposed on other branches of industry, deprived Ireland of her most promising sources of wealth, drove great multitudes of energetic Protestants out of the country, and threw the people more and more upon the soil as almost their sole means of support.

The penal laws against the Catholics accompanied or closely followed the commercial restraints. The blame of them may be divided with some equality between the Government of England and the Parliament of Ireland. It was the Irish Parliament which enacted these laws, but an English Act first made the Irish Parliament exclusively Protestant, and the whole legislation was carried at a time when the Irish Parliament was completely dependent, and incompetent even to discuss any measure without the previous approbation of the English Government. In order to judge this legislation with equity, it must be remembered that in the beginning of the eighteenth century restrictive laws against Protestantism in Catholic countries, and against Catholicism in Protestant ones, almost universally prevailed. The laws against Irish Catholics were, on the whole, less stringent than those against Catholics in England. They were largely modelled after the French legislation against the Huguenots, but persecution in Ireland never approached in severity that of Louis XIV., and was absolutely insignificant compared with that which had extirpated Protestantism and Judaism from Spain. The code, however, was not mainly the product of religious feeling, but of policy, and in this respect it has been defended in its broad outlines, though not in all its details, by such Irishmen as Charlemont, Flood, and Parsons. They argued that at the close of a long period of savage civil war it was absolutely necessary for a small minority, who found themselves in possession of the government and land of the country, to deprive the conquered and hostile majority of every element of political and military strength. This was the real object of the code. It was a measure of self-defence justified by necessity and by the fact that it produced in Ireland for the space of about eighty years the most perfect tranquillity.

There is much truth in these considerations, but it is also true that the penal code produced more pernicious moral, social, and political effects than many sanguinary persecutions. In other countries disqualifying or persecuting laws were directed against small fractions of the nation. In Ireland they were directed against the bulk of the community. Being supported by little or no genuine religious fanaticism or proselytising ardour, they made few Protestants except in the upper orders, where many conformed in order to keep their land or to enter professions; but they drove nearly all the best and most energetic Catholics to the Continent; they discouraged industry; closed the door of knowledge; taught the people to look upon law as something hostile to religion; introduced division and immorality into families by the rewards they offered to apostasy; and condemned the whole country to poverty and impotence by fatally depressing the great majority of its people. Under the influence of the penal laws the Catholics inevitably acquired the vices of serfs, and the Protestants the vices of monopolists. A great portion of the code was pronounced, with good reason, to be flagrantly opposed to the articles of the Treaty of Limerick, and it completed the work of the confiscations by making the landlord class in Ireland almost wholly Protestant, while the great majority of the tenantry were Catholics.

There was a moment, however, in the beginning of the century when the whole current of Irish history might easily have changed. Scotland had suffered, like Ireland, from the protective policy that followed the Revolution, and her independent Parliament had retaliated by measures which threatened the speedy separation of the two crowns, and soon led to a legislative Union. In Ireland such a Union was ardently desired by enlightened Irishmen, and there is every reason to believe that it could then have been carried with universal consent. The Catholics were perfectly passive, and would gladly have accepted a change which withdrew them from the direct government of the conquerors in a recent civil war. The Protestants had as yet no distinctively national feeling, and a legislative Union would have emancipated their industry and added enormously to their security. Molyneux, the first great champion of the legislative independence of Ireland, emphatically declared that he and those who thought with him would gladly have accepted the alternative of a Union, and both the Irish Houses of Parliament voted addresses in favour of such a measure. If it had been carried, Ireland would have been at least saved from the evils that rose from the commercial restrictions and from the extreme jobbing that grew up around the local legislature, and she would, perhaps, have been saved from some parts of the penal code. But the golden opportunity was lost. The English commercial classes dreaded Irish competition in their markets, and the petition of the Irish legislature was disregarded.

Nearly seventy years of quiet followed. The establishment of the Hanoverian dynasty, the Jacobite risings of 1715 and 1745, the different wars in which England was engaged, left Ireland absolutely undisturbed. The House of Commons then sat for a whole reign and met only every second year. It was completely subservient to the English Privy Council, and it consisted so largely of nomination boroughs that a few great nobles commanded a decisive preponderance, and they practically conducted the government and administered the patronage of Ireland. There was great jobbing and corruption, but taxation, on the whole, was exceedingly light, and there was no tendency to throw it unduly on the poor, or to create in Ireland any of the many feudal burdens that prevailed in France and Germany. The practical evil most felt was the system of tithes for the support of the Protestant establishment, and it was aggravated by a very unfair exemption of pasture land, and also by the prevailing system of farming out tithes to a class of men known as tithe proctors. In the country districts all power was concentrated in the hands of the landlords, who, with many faults and under many difficulties, at least succeeded in attaining a large measure of genuine popularity.
