As your father's remark was so important, let us try to understand its meaning. He mentioned two countries, Austria and Servia, and you would easily guess that there was some quarrel between them. It is not easy to explain to you exactly what the quarrel was about, and perhaps you will find the explanation a little dull; but if you are really to understand how the war arose, you must not mind a little dulness. We shall come to the exciting events by-and-by.

Look at the map on the next page. It shows you the two countries which had fallen out—Austria and Servia. You see at a glance that the Austrian Empire, which consists of Austria and Hungary, is by far the larger country; in fact, Austria-Hungary is seven times as large as Servia, and has eleven times as many people. There is no country on earth which contains so many different races as Austria-Hungary. Within its bounds we find Germans, Italians, Magyars,[5] Jews, Armenians,[6] and Gypsies, as well as eight distinct Slav races.

You will come across the word Slav many times in these pages, so I must explain it to you at once. By the word Slav we mean a member of that branch of mankind known as the Slavonic race. The Slavs inhabit most of the east of Europe and a large part of Asia, and they are really more Asiatic than European. Most of the Russians and the Christian peoples of the Balkan Peninsula are Slavs, and so, too, are the Poles, who live partly in Austria, partly in Germany, and partly in Russia. In Austria, and especially in Hungary, there are many Slav races, but the ruling peoples in these countries are Germans in Austria and Magyars in Hungary.

The Servians are Slavs. They are a tall, handsome race, and are very warlike in character. During the recent war in the Balkans they fought very bravely and successfully against the Turks. At the end of the war the Powers of Europe gave them more than 15,000 square miles of fresh territory. The Servians have always been ambitious, and they wish their country to become great and powerful.

Now look at your map again, and find the river Save, which joins the Danube at Belgrade,[7] the capital of Servia. South of the Save you see a country marked Bosnia,[8] and, still farther south, another country marked Herzegovina.[9] You are sure to notice that these two countries stand between Servia and the Adriatic Sea, and that they belong to Austria. Both Bosnia and Herzegovina are inhabited by Slavs, who hate being under Austria, and are eager to join their kinsmen the Servians. You cannot blame them for this, because they naturally would like to form one kingdom with men of their own race, religion, and modes of life. Besides, they feel that they have been very badly treated. Let me explain.
