The Don Cossacks appear to us for the first time in the thirteenth century, on the ruins of the Tatar empire. Not till then did they begin to make a certain figure in the history of the Muscovite empire. In the reign of Ivan IV. the Terrible, they put themselves under the protection of Russia. From that time until near the end of the last century, we see them sometimes marching under the banners of the Muscovite sovereigns, sometimes rising against them, and often bringing the empire to the very verge of ruin. Their political condition was in those days a real republic, founded on a basis of absolute equality. The head of the government, styled ataman, was selected by the whole assembled nation, and retained his office but for five years; but his power was dictatorial, and no one could call him to account for his acts, even after the expiration of his office. All the subaltern leaders were likewise elected, and retained their posts for a greater or less time, according to circumstances. Equality, however, resumed its sway at the end of each military campaign; each officer, on returning into private life, enjoyed only the rights common to all; and the colonel or starshine often made the ensuing campaign as a private soldier. Aristocracy was totally unknown to the Don Cossacks in those days; if some families were distinguished from the rest by their greater influence, they owed this solely to their courage and their exploits. So strong was then the sense of independence, that the Cossacks despised as vile mercenaries those who took permanent service under the Russian sovereigns. As for the imperial suzerainty, it was limited to the right of calling for a military contingent in case of war, and of disposing of a small body of troops to defend the frontiers against the nomades of the steppes.
Cossack freedom was doomed to perish when brought into collision with the principles of absolutism and servitude which rule in the Russian empire; accordingly, as soon as the Empress Catherine II. felt strong enough to make the attempt, she decided on a radical change in the political constitution of the Don country.
The first of her ukases to this effect enacted that all the Cossack officers in the service of Russia should retain their rank and privileges on their return to their own country; a regulation directly opposed to the habits and usages of that republican people. How, indeed, could that haughty soldiery have endured that slave-officers, as it called them, should be put on the same footing with its own, elected by the acclamations of the nation? A revolt ensued, but it was promptly put down. The illustrious Potemkin could not understand that insurrection, for it seemed to him incredible that the Cossacks should rebel because they were granted almost all the privileges of Russian officers. After these unhappy troubles, their elections were abolished, and their political system was gradually changed, until it came to resemble that of a Russian government. Count Platof was the last ataman of the Cossacks, and he owed the authority he was allowed to enjoy, in a great measure to the peculiar circumstances in which he was placed by the wars of the empire.
The Don country continued through the last century as before, to be a land of asylum and freedom for all refugees. This led to the settlement of a great number of Russians among the Cossacks. The Emperor Paul took advantage of this circumstance to secure the attachment of the principal families by publishing an ukase, in which he at once, and without warning, declared all the Russian fugitives slaves of the landowners, whose patronage they had accepted. This first partition of the people was not the last; another ukase of the same sovereign completed the work of Catherine II., abolished equality, and constituted an aristocracy by ennobling all the officers and employes of the government. The nobility at present amount to a considerable number, and all the officers are taken from that body. The young Cossacks, like the Russians, enter the St. Petersburg corps as cadets, at ten or twelve years of age; after some years they join a regiment as junker, and two or three months afterwards they become officers.
The political power of the Cossacks being annihilated, active means were taken to deprive them of all military strength, by dispersing them all over the empire, and stationing them wherever there were quarantines, custom-house lines, and hostile frontiers to guard. Cossack posts were simultaneously established on the frontiers of Poland, and at the foot of the Caucasus. Lastly, every means of enfeeblement was largely employed, and after the death of Platof, under pretext of rewarding the nation for its devotedness during the campaign of Moscow, the functions of ataman-in-chief were suppressed, and the title was conferred on the heir-apparent.
