As regards French territorial expansion, Russia could initially also take a relaxed view. France was at the other end of Europe. It would have to expand some distance before Russia’s interests were challenged. By contrast, any advance would quickly carry French troops into the Rhineland and into Belgium, thereby touching on essential Habsburg and British interests. With Britain, France, Austria and perhaps even Prussia embroiled at the other end of Europe, Russia need have no fears for its security and could pursue her interests with confidence, not least in Poland.31
By the late 1790s Russia could no longer afford to be quite so relaxed. De facto French annexation of the Rhineland, Switzerland, the Netherlands and parts of Italy added up to a worrying increase in French power. With French eyes turning to the eastern Mediterranean and even Ottoman Egypt, Paul I had some reason to join the Second Coalition. The manner in which he did so showed, however, that he regarded Russia as an auxiliary in a war whose front-line belligerents were Austria and Britain. Moreover, within a year of Russian troops going into action Paul had fallen out with his allies. By the last year of his reign he had reversed his position entirely. Russia withdrew from the coalition, banned all trade with Britain, headed a new league to secure neutral countries’ maritime rights, and even sent off a Cossack force on a fanciful expedition towards India. By the time Paul was assassinated in March 1801 Russia to most intents and purposes had allied itself to France in its war against Britain.
The new emperor, Alexander I, immediately restored good relations with Britain but his main initial priority was to steer clear of international entanglements and devote himself to internal reforms. Only in 1804 did Russo-French relations once again begin to slide towards war. The main reason for this was that the geopolitical concerns that had taken Russia into the Second Coalition had reappeared but in sharper form. France was now considerably more powerful than it had been in 1798. Under French pressure the Holy Roman Empire was being dismantled and Germany was being rearranged without reference to Russian interests. By proclaiming himself King of Italy in 1804 Napoleon was not just asserting his domination of the peninsula: he was also establishing powerful bases for French expansion into the eastern Mediterranean, the Balkans and Constantinople. To these fundamental concerns Napoleon’s abduction and subsequent murder of the Duc d’Enghien, a junior member of the exiled French royal family whom he had lifted from the territory of Alexander’s father-in-law, added an element of moral outrage. Many French royalist émigrés lived in Petersburg and the Russian aristocracy saw in Enghien’s murder a confirmation that Napoleon was the true heir of Jacobin terror. Alexander himself was much less of a legitimist than these Petersburg grandees but Napoleon’s treatment of Enghien was by no means the only example of the French leader’s contempt for international treaties and norms.32
All these factors took Russia to war in 1805. On this occasion the Russian commitment was more whole-hearted than it had been in 1798. Nevertheless Alexander still saw Austria, Britain and Prussia as the front-line antagonists, to whom Russia was offering unselfish assistance though its own vital interests were not directly engaged. Annoyance that Prussia was unwilling to do its duty led him to plan to coerce Berlin into joining the coalition. Though he kept a clear eye on Russian interests, Alexander also floated grandiose principles to underpin lasting European peace and security. A child of the Enlightenment, he liked to speak and see himself in such terms. But his at times almost Wilsonian tendency to proclaim great principles of international order was also rooted in a rather American sense that a country of Russia’s power and geopolitical security could afford to stand on a hill above the common ruck of states and lay down rules for the common good.33
