In order to know how to do this, we must study the causes of the wars of the past. We shall find, as we do so, that almost all wars can be traced to one of four causes: (1) the instinct among barbarous tribes to fight with and plunder their neighbors; (2) the ambition of kings to enlarge their kingdoms; (3) the desire of the traders of one nation to increase their commerce at the expense of some other nation; (4) a people's wish to be free from the control of some other country and to become a nation by itself. Of the four reasons, only the last furnishes a just cause for war, and this cause has been brought about only when kings have sent their armies out, and forced into their kingdoms other peoples who wished to govern themselves.

To search for the causes of the great war which began in Europe in 1914, we must go far back into history. It should be remembered that many of the governments of today have not lived as long as that of our own country. This is, perhaps, a new thought to some of us, who rather think that, as America is a new country, it is the baby among the great nations. But, one hundred and thirty years ago, when the United States was being formed, there was no nation called Italy; the peninsula which we now know by that name was cut up among nine or ten little governments. There was no nation known as Germany; the land which is in the present German empire was then divided among some thirty or thirty-five different rulers. There was no Republic of France; instead, France had a king whose will was law, and the French people were cruelly oppressed. There was no kingdom of Belgium, no kingdom of Serbia, of Bulgaria, of Roumania. The kingdom of Norway was part of Denmark. The Republic of France, as we now know it, dates back only to 1871; the Empire of Germany and the United Kingdom of Italy to about the same time. The kingdoms of Roumania, Serbia, and Bulgaria have been independent of Turkey only since 1878. The kingdom of Albania did not exist before 1913. Most of the present nations of modern Europe, then, are very new. The troubles which led to the great war, however, originated in the dim twilight of history.

In the earliest days, there were no separate countries or kingdoms. Men gathered together in little bands, each of which had its leader. This leader was generally chosen because of his bodily strength and courage. He was the best fighter of the tribe. The people did not have any lasting homes. They moved around from place to place, wherever they could find the best hunting and fishing. When two tribes wanted the same hunting grounds, they fought, and the weaker party had to give way. Selfishness was supreme. If a man wanted anything which belonged to his weaker neighbor, he simply beat this neighbor over the head with his club, and took it. The stronger tribe attacked the weaker, without any thought of whether or not its quarrel was just.

Gradually, in the southern and warmer parts of Europe, the tribes began to be more civilized. Towns sprang up. Ships were built. Trade came to be one of the occupations. The fighting men needed weapons and armor; so there grew up artisans who were skilled in working metals. In Egypt and Syria there were people who had reached quite a high degree of civilization, and gradually the Europeans learned from them better ways of living. First the Greeks, then the Etruscans (Ē-trŭs′cans), a people who lived in Italy just north of where Rome now is, and finally the southern Italians learned that it was possible to live in cities, without hunting and plundering. Grazing (the tending of flocks of animals) came to be the occupation of many. The owners of sheep or cattle drove their flocks from place to place, as grass and water failed them where they were. There was no separate ownership of land.

At last came the rise of the city of Rome, which, starting out as the stronghold of a little gang of robbers, spread its rule gradually over all the surrounding country. By this time, the barbarians of northern Europe had gotten past the use of clubs as weapons. They, too, had learned to make tools and arms of bronze, and those living near civilized countries had obtained swords of iron. The club, however, still remained as the sign of authority. The large bludgeon of the chief was carried before the tribe as a sign of his power over them. You have all seen pictures of a king sitting on his throne and holding a wand or stick in his right hand. It is interesting to think that this scepter, which the present king of England carries on state occasions to remind his people of his power, is a relic of the old, old days when his grandfather, many times removed, broke the head of his rival for leadership in the tribe and set up his mighty club for his awestruck people to worship.

The city of Rome (at first a republic, afterwards an empire) spread its rule over all of Italy, over all the shores of the Mediterranean Sea, and finally over all the countries of Europe south and west of the rivers Danube and Rhine. One of the emperors planted a colony north of the Danube near its mouth, and the descendants of these colonists are living in that same country today. They have not forgotten their origin, for they still call themselves Romans (Roumani [Ro͞o-mä′ni]), and talk a language greatly resembling the Latin, which was the tongue spoken by the Romans of old. With the exception of this country, which is now Roumania, the part of Europe north and east of the Danube and Rhine was practically free from the Romans. In this territory, roving bands wandered around, driving their cattle with them and clearing the woods of game.

In some ways, the Romans were a highly civilized people. They had schools where their children were taught to read and write, to speak Greek, and to work problems in geometry. They had magnificent public buildings, fine temples and palaces. They built excellent paved roads all over the southern part of Europe, and had wonderful systems of aqueducts which supplied their cities with pure water from springs and lakes miles away. Their dress was made of fine cloth. They knew how to make paper, glass, and steel.

On the other hand, they were a cruel and bloodthirsty people. Their favorite amusement was to go to shows where gladiators fought, either with each other or with wild beasts. These gladiators were generally men from tribes which had fought against Rome. They had been captured and brought to that city, where they were trained to use certain weapons. Then on holidays, with all the people of Rome packed into big amphitheaters, these unfortunate captives were forced to fight with each other until one man of each pair was killed. It occasionally happened that one
