_The Use of Land the Foundation of Social Order_.--The manner in which tribes and nations have attached themselves to the soil has determined the type of social organization. Before the land was treated as property of individuals or regarded as a permanent possession by tribes, the method in which the land was held and its use determined the quality of civilization, and the land factor became more important as a determiner of social order as civilization progressed. It was exceedingly important in determining the quality of the Greek life, and the entire structure of Roman civilization was based on the land question. Master the land tenure of Rome and you have laid the foundation of Roman history. The desire for more land and for more room was the chief cause of the barbarian invasion of the empire. All feudal society, including lords and vassals, government and courts, was based upon the plan of feudal land-holding. In modern times in England the land question has been at times the burning political and economic question of the nation, and is a disturbing factor in recent times. In the United States, rapid progress is due more to the bounteous supply of free, fertile lands than to any other single cause. Broad, fertile valleys are more pertinent as the foundation {146} of nation-building than men are accustomed to believe; and now that nearly all the public domain has been apportioned among the citizens, intense desire for land remains unabated, and its method of treatment through landlord and tenant is rapidly becoming a troublesome question. The relation of the soil to the population presents new problems, and the easy-going civilization will be put to a new test.
