The history of the development of forestry in Germany may be divided into periods variously. Bernhardt recognizes six periods; Schwappach makes four divisions, namely, the first, from the earliest times to the end of the Carlovingians (911), which is occupied mainly with the development of forest property conditions; the second, to the end of the Middle Ages (1500), during which the necessity of forest management begins to be sporadically recognized; the third, to the end of the 18th century, during which the foundation for the development of all branches of forestry is laid; the fourth, the modern period, accomplishing the complete establishment of forestry methods in all parts of Germany. For the later historian it would be proper to recognize a fifth period from about 1863, when, by the establishment of experiment stations, a breaking away from the merely empiric basis to a more scientific foundation of forestry practice was begun. For our purposes we shall be satisfied with a division into three periods, namely: first, to the end of the middle ages, when, with the discoveries of America and other new countries, an enlargement of the world’s horizon gave rise to a change of economic conditions; second, to the end of the eighteenth century, when change of political and economic thought altered the relation of peoples and countries; third, the modern period, which exhibits the practical fruition of these changes. I. FROM EARLIEST TIMES TO END OF MIDDLE AGES. Many of the present conditions, especially those of ownership, as well as the progress in the development both of forest policy and of forest management, can be understood only with some knowledge of the early history of the settlement of the country.[3] [3] FELIX DAHN, _Urgeschichte der germanischen und romanischen Völker_, 1881. As is well known, Aryan tribes from central Asia had more than a thousand years before Christ begun to overrun the country. These belonged to the Keltic (Celtic) or Gaelic race which had gradually come to occupy partly or wholly, France, Spain, northern Italy, the western part of Germany and the British Islands. They were followed by the _Germani_ (supposedly a Celtic word meaning neighbor or brother), also Aryan tribes, who appeared at the Black Sea about 1000 B.C., in Switzerland and Belgium about 100 B.C. These were followed by the Slovenes, Slovaks, or Wends, crowding on behind, disputing and taking possession of the lands left free by, or conquered from the Germani. Through these migrations, by about 400 A.D., the whole of Western Europe seems to have been fully peopled with these tribes of hunters and herders. The mixture of the different elements of victors and vanquished led to differentiation into three classes of people, economically and politically speaking, namely the free, the unfree (serfs or slaves), and the freedmen--an important distinction in the development of property rights. 1. _Development of Property Conditions._
