In the year 1877, when Turkey was master of the Balkan Peninsula, Russia made up her mind to fight the Turks. The Austrians were afraid that the Russians would beat the Turks, and take from them the city of Constantinople. The Russians, as you know, have a very poor sea coast. Away fronting the Arctic Ocean they have a strip of coast, but it is of very little use to them, as it is frozen up for a large part of the year. So, too, is their coast on the Baltic Sea. In the south they have a good deal of coast on the Black Sea; but in order to get from the Black Sea to the Mediterranean Sea, and so to the oceans of the world, they have to pass through two narrow straits, known as the Bosporus[10] and the Dardanelles.[11] The Turks hold these straits, and they can shut them against ships at any time. So you see that the Russians can only carry on trade in the south by leave and licence of Turkey. If they could obtain possession of Constantinople all their difficulties would vanish. They would be masters of a port which would enable them to become a great sea power.

Now, Austria is even worse off than Russia in the matter of sea coast. She has about a thousand miles of seaboard on the Adriatic Sea, and there are many excellent harbours and deep and sheltered bays on it; but, unfortunately, a long range of steep limestone mountains cuts them off from the interior, and makes communication very difficult. There is a mountain railway joining the port of Trieste[12] with the interior, but it is easier to send bulky produce down the Danube to the Black Sea than across the mountains. Austria has always longed for better access to the sea, and lately she has coveted the port of Salonica,[13] which you will find on the Ægean[14] Sea.
This map shows what Servia would become if Bosnia and Herzegovina were to be united with her.
When, therefore, Russia was about to fight Turkey, the Austrians feared that all the Balkans would come under Russian sway, and that their hopes of gaining power in the peninsula would be vain. So they prepared to fight Russia, but were bought off. Russia secretly promised Austria that if she would stand out of the fight she should receive as her reward the provinces of Bosnia and Herzegovina. Austria stood out, and when the war was over the Great Powers said that she might rule these two provinces, though they were not to become her actual property. You can easily imagine the anger of the people of Bosnia and Herzegovina when they found themselves handed over to Austria, just as though they were a flock of sheep to be bought and sold. Ever since 1878 the Austrians have ruled them; but they have always been discontented, and when, in 1908, they were told that they now belonged wholly and entirely to Austria, their anger knew no bounds. During the recent Balkan War they saw the peasant soldiers of Servia conquering on the battlefield, and they hoped that when the war was over they might be allowed to join Servia, and with her form one strong state. Servia would have welcomed them with open arms, but, as you know, they were doomed to disappointment. Both Servia and Russia were much annoyed when Austria annexed the two provinces. The anger of Russia and Servia nearly brought about another war.
Such was the state of things at the beginning of June in the year 1914.
