In this mountainous country between two seas, more babies are born every day than in any other country in Europe. There are 29 million people in Spain already, although it is only the size of our state of Montana, where 600,000 people live. This country might seem very small to us, but it is the third largest country in Europe. And because their mountains shut different parts of the country away from each other, there are many differences in ways of living among the 29 million Spaniards. There are 15 different regions in Spain, and each one has a different way of dressing, different music and dances, different ways of fixing food, a different sort of house to live in, and even different ways of speaking. Sometimes you will meet a Spaniard who has never been out of his own region, or even away from his own village, because the mountains make it very difficult to travel when your way of getting around is on your own two feet or in a little cart pulled by a small burro or donkey. [Illustration] Another reason for the many different ways of living is that Spain is a very old country which has been invaded many times by other countries. These countries were jealous of the beauty and wealth of Spain and wanted to get it for themselves. For hundreds of years the Spanish people were always fighting to protect their beloved homeland against invading armies. [Illustration] The Iberians themselves were invaders, because they weren't the first people who lived in Spain. We don't even know the names of those very first people who lived there when most of Europe was covered with ice. We only know that they lived in caves and hunted wild animals, because some of their caves have been discovered and the walls are covered with bright drawings of the animals these people hunted--bison, deer, wild horses and wild boars. [Illustration] After the Iberians, came the Celts, Greeks, Phoenicians, Carthaginians and Romans. From Rome, Spain took her language, her system of laws, and her church. There were once more than 80 Roman cities in Spain, with roads and bridges and walls which were built so well that they are still used by Spanish people today. In the city of Segovia, the Romans built an aqueduct to bring drinking water into the town from the nearby mountains, and this aqueduct still brings water to the people of Segovia.
