This book traces the extent of territory which the different states and nations of Europe and the neighbouring lands have held at different times in the world's history, to mark the different boundaries which the same country has had, and the different meanings in which the same name has been used. It is of great importance carefully to make these distinctions, because great mistakes as to the facts of history are often caused through men thinking and speaking as if the names of different countries, say for instance England, France, Burgundy, Austria, have always meant exactly the same extent of territory.
