settlement which has made the English name famous was made in an island. But, when England had become the name of a distinct political dominion, its meaning was liable to change as that dominion advanced or went back. Thus the borders of England and Scotland have greatly changed at different times, and forgetfulness of this has led to many misunderstandings in reading the history of the two countries. And so with all other cases of the kind; the physical nature of the country, and the settlements of the different nations which have occupied it, have always been the determining causes of its political divisions. But it is with the political divisions that historical geography has to deal in the first place. With the nature of the land, and with the people who occupy it, it has to deal only so far as they have influenced the political divisions. Our present business in short is, first to draw the map of the countries with which we are concerned as it appeared after each of the different changes which they have gone through, and then to point out the historical causes which have led to the changes on the map. In this way we shall always see what was the meaning of any geographical name at any particular time, and we shall thus avoid mistakes, some of which have often led to really important practical consequences. ♦Distinction of Geographical and Political Names.♦ From this it follows that, in looking at the geography of Europe for our present purpose, we must look first at the land itself, and then at the nations which occupy it. And, in so doing, it may be well first of all to distinguish between two kinds of names which we shall have to use. Some names of countries are strictly geographical; they really mean a certain part of the earth’s surface marked out by boundaries which cannot well be changed. Others simply mean the extent of country which is occupied at any time by a particular nation, and whose boundaries may easily be changed. Thus _Britain_ is a strictly geographical name, meaning an island whose shape and boundaries must always be nearly the same. _England_, _Scotland_, _Wales_, are names of parts of that island, called after different nations which have settled in it, and the boundaries of all of which have differed greatly at different times. _Spain_ again is the geographical name of a peninsula which is almost as well marked out by nature as the island of Britain. _Castile_, _Aragon_, _Portugal_, are political names of parts of the peninsula of Spain. They are the names of states whose boundaries have greatly varied, and which have sometimes formed separate governments and sometimes have been joined together.[1] _Gaul_ again is the geographical name of a country which is not so clearly marked out all round by nature as the island of Britain and the peninsula of Spain, but which is well marked on three sides, to the north, south, and west. Within the limits of Gaul, names like
