Czechs, Yugoslavs, and Poles

Something must now be said about the growth of the national movements, which, under the eventual protection of the Allies, were to result in the foundation of new states or the resurrection of long-defunct ones at the end of the war. There were three such movements: that of the Czechs, with the more backward Slovaks in tow; that of the South Slavs, or Yugoslavs (Serbs, Croats, and Slovenes); and that of the Poles. The Czech country, namely Bohemia and Moravia, belonged in 1914 to the Austrian half of the Habsburg monarchy, the Slovak to the Hungarian half. The Yugoslavs had already been represented in 1914 by two independent kingdoms, Serbia and Montenegro, but they were also predominantly numerous in territories still under Habsburg rule: Serbs in Bosnia and Hercegovina (an Austro-Hungarian condominium) and in Dalmatia (an Austrian possession); Croats in Croatia (Hungarian), in Istria (Austrian), and in Dalmatia; Slovenes in Istria and in Illyria (Austrian likewise). Poland was divided into three parts: Germany had the north and the west as provinces of the Kingdom of Prussia; Austria had Galicia (including an ethnically Ukrainian extension to the east); Russia had the rest.

The Czechs had long been restless under the Austrian regime, and one of their leading intellectual spokesmen, Tomáš Masaryk (in fact a Slovak), had already envisaged the carving of Czechoslovak and Yugoslav states out of Austria-Hungary in December 1914. In 1916 he and a fellow émigré, Edvard Beneš, based respectively in London and in Paris, organized a Czechoslovak National Council. The western Allies committed themselves to the Czechoslovak idea from 1917 onward, when Russia’s imminent defection from the war made them ready to exploit any means at hand for the disabling of Austria-Hungary; and Wilson’s sympathy was implicit in his successive peace pronouncements of 1918.

For the South Slavs of Austria-Hungary the Yugoslav Committee, with representatives in Paris and in London, was founded in April 1915. On July 20, 1917, this committee and the Serbian government in exile made the joint Corfu Declaration forecasting a South Slav state to comprise Serbs, Croats, and Slovenes.

The Polish nationalist leaders in the first years of the war were uncertain whether to rely on the Central Powers or on the Allies for a restoration of Poland’s independence. So long as the western Allies hesitated to encourage Polish nationalism for fear of offending imperial Russia, the Central Powers seemed to be the most likely sponsors; and Austria at least allowed Józef Piłsudski, from 1914, to organize his volunteer Polish legions to serve with Austrian forces against the Russians. Austria’s benevolence, however, was not reflected by Germany; and when the Two Emperors’ Manifesto of November 5, 1916, provided for the constitution of an independent Polish kingdom, it was clear that this kingdom would consist only of Polish territory conquered from Russia, not of any German or Austrian territory. When, after the March Revolution of 1917, the Russian provisional government had recognized Poland’s right to independence, Roman Dmowski’s Polish National Committee, which from 1914 had been functioning in a limited way under Russian protection, could at last count seriously on the sympathy of the western Allies. While Piłsudski declined to raise a Polish army to fight on against the new Russia, a Polish army was formed in France, as well as two army corps in Belorussia and in Ukraine, to fight against the Central Powers. The Bolshevik Revolution and Wilson’s Fourteen Points together consummated the alignment of the Poles on the side of the western powers.

Eastern Europe and the Russian periphery, March–November 1918

The Treaty of Brest-Litovsk (March 3, 1918) gave Germany a free hand to do what it liked with Russia’s former possessions in eastern Europe. While they pursued their plan of 1916 for a kingdom of Poland, the Germans took new measures for the other countries. Lithuania, recognized as independent, was to be a kingdom under some German prince. Latvia and Estonia were to be merged into a grand duchy of the Baltikum under the hereditary rule of Prussia. An expeditionary force of 12,000 men, under General Graf Rüdiger von der Goltz, was sent to Finland to uphold the Finnish general C.G.E. Mannerheim’s nationalist forces against the Red Guards, whom the Bolsheviks, despite their recognition of Finland’s independence, were now promoting there. And finally, the Ukrainian nationalist government, which had already been challenged by a Communist one before its separate peace with the Central Powers (Brest-Litovsk, February 9), was promptly displaced by a new regime after the advance of German and Austro-Hungarian troops into its territory.

The Romanian armistice of December 1917 was converted into the Treaty of Bucharest on May 7, 1918. Under this treaty’s terms, southern Dobruja was ceded to Bulgaria; northern Dobruja was put under the joint administration of the Central Powers; and the latter obtained virtual control of Romania’s oil fields and communications. Romania, on the other hand, had some consolation from Bessarabia, whose nationalists, after receiving Romanian assistance against the Bolsheviks, had voted in March 1918 for their country’s conditional union with Romania.

Even Transcaucasia began to slide into the German camp. The short-lived federal republic was dissolved by its three members’ individual declarations of independence—Georgia’s on May 26, Armenia’s and Azerbaijan’s on May 28. Treaties of friendship were promptly signed between Georgia and Germany and between Armenia and Turkey, and Turkish troops advanced into Azerbaijan, where they occupied Baku on September 15. The western Allies, meanwhile, were hoping that some new semblance of an Eastern Front could be conjured up if they supported the various and growing forces in Russia that were opposed to the peacemaking Bolsheviks. Since the Black Sea and the Baltic were closed to them, the Allies could land troops only on Russia’s Arctic and Pacific shores. Thus, the Allied “intervention” in Russia on the side of the anti-Bolshevik (“White”) forces, long to be execrated by Soviet historians, began with an Anglo-French landing at Murmansk, in the far north, on March 9, 1918. The subsequent reinforcement of Murmansk made possible the occupation of the Murmansk railway as far south as Soroka (now Belomorsk); and a further landing at Arkhangelsk in the summer raised the total Allied strength in northern Russia to some 48,000 (including 20,000 Russian “Whites”). By this time, moreover, there were some 85,000 interventionist troops in Siberia, where a strong Japanese landing at Vladivostok in April had been followed by British, French, Italian, and U.S. contingents. A “White” provisional government of Russia was set up at Omsk, with Admiral A.V. Kolchak as its dominant personality. The “White” resistance in the south of European Russia, which had been growing since November 1917, was put under the supreme command of General A.I. Denikin in April 1918.
