The progress of empire, in the early ages of Europe, threatened to be rapid, and to bury the independent spirit of nations in a grave like that which the Ottoman conquerors found for themselves, and for the wretched race they had vanquished. The Romans had by slow degrees extended their empire; they had made every new acquisition in the result of a tedious war, and had been obliged to plant colonies, and to employ a variety of measures, to secure every new possession. But the feudal superior being animated, from the moment he gained an establishment, with a desire of extending his territory, and of enlarging the list of his vassals, procured, by merely bestowing investiture, the annexation of new provinces, and became the master of states, before independent, without making any material innovation in the form of their policy.
Separate principalities were, like the parts of an engine, ready to be joined, and, like the wrought materials of a building, ready to be erected. They were in the result of their struggles put together or taken asunder with facility. The independence of weak states was preserved only by the mutual jealousies of the strong, or by the general attention of all to maintain a balance of power.
The happy system of policy on which European states have proceeded in preserving this balance; the degree of moderation which is, in adjusting their treaties, become habitual even to victorious and powerful monarchies, does honour to mankind, and may give hopes of a lasting felicity, to be derived from a prepossession, never, perhaps, equally strong in any former period, or among any number of nations, that the first conquering people will ruin themselves, as well as their rivals.
It is in such states, perhaps, as in a fabric of a large dimension, that we can perceive most distinctly the several parts of which a political body consists; and observe that concurrence or opposition of interests, which serve to unite or to separate different orders of men, and lead them, by maintaining their several claims, to establish a variety of political forms. The smallest republics, however, consist of parts similar to these, and of members who are actuated by a similar spirit. They furnish examples of government diversified by the casual combinations of parties, and by the different advantages with which those parties engage in the conflict.
In every society there is a casual subordination, independent of its formal establishment, and frequently adverse to its constitution. While the administration and the people speak the language of a particular form, and seem to admit no pretensions to power, without a legal nomination in one instance, or without the advantage of hereditary honours in another, this casual subordination, possibly arising from the distribution of property, or from some other circumstance that bestows unequal degrees of influence, gives the state its tone, and fixes its character.
The plebeian order at Rome having been long considered as of an inferior condition, and excluded from the higher offices of magistracy, had sufficient force, as a body, to get this invidious distinction removed; but the individual still acting under the impressions of a subordinate rank, gave in every competition his suffrage to a patrician, whose protection he had experienced; and whose personal authority he felt. By this means the ascendancy of the patrician families was, for a certain period, as regular as it could be made by the avowed maxims of aristocracy: but the higher offices of state being gradually shared by plebeians, the effects of former distinctions were prevented or weakened. The laws that were made to adjust the pretensions of different orders were easily eluded. The populace became a faction, and their alliance was the surest road to dominion. Clodius, by a pretended adoption into a plebeian family, was qualified to become tribune of the people; and Caesar, by espousing the cause of this faction, made his way to usurpation and tyranny.
In such fleeting and transient scenes, forms of government are only modes of proceeding, in, which successive ages differ from one another. Faction is ever ready to seize all occasional advantages; and mankind, when in hazard from any party, seldom find a better protection than that of its rival. Cato united with Pompey in opposition to Caesar, and guarded against nothing so much as that reconciliation of parties, which was in effect to be a combination of different leaders against the freedom of the republic. This illustrious personage stood distinguished in his age like a man among children, and was raised above his opponents, as much by the justness of his understanding, and the extent of his penetration, as he was by the manly fortitude and disinterestedness with which he strove to baffle the designs of a vain and childish ambition, that was operating to the ruin of mankind.
Although free constitutions of government seldom or never take their rise from the scheme of any single projector, yet are they often preserved by the vigilance, activity, and zeal of single men. Happy are they who understand and who choose this object of care; and happy it is for mankind when it is not chosen too late. It has been reserved to signalize the lives of a Cato or a Brutus, on the eve of fatal revolutions; to foster in secret the indignation of Thrasea and Helvidius; and to occupy the reflections of speculative men in times of corruption. But even in such late and ineffectual examples, it was happy to know, and to value, an object which is so important to mankind. The pursuit, and the love of it, however unsuccessful, has thrown its principal lustre on human nature.
