With the extension of trade and travel, and especially with the upgrowth of the feudal system, however, the utility of intercourse with peaceable strangers, and the advantage of adding their personal prowess, capacity, and assets to the resources of the community, came to be more and more recognized, and the stranger within the gates was accorded an increasing measure of tolerance, not to say welcome. But this tolerance was at best of a very limited character; practically, it was not much more than a rigid systematizing of the ways of making the immigrant useful and contributory. It is not the province of this report to dilate upon this branch of the subject. Suffice it to say that to this day, over nearly the whole earth, the alien is still subject to marked limitations, and that the exploitation of him is neither a modern nor an American invention. As for political rights, let alone any degree of participation in the functions of government, no nation ever has contemplated the possibility of such a thing--until a few of the American states, clamoring for population from any corner of humanity, offered virtually full political participation to the alien immediately upon his mere declaration of intention to apply for citizenship--some day! Until the excitement of the World War brought public attention to the whole question of the position and influence of the foreign born in America, this anomaly remained in force in at least a dozen states: Alabama, Arkansas, Arizona, Indiana, Kansas, Michigan, Missouri, Nebraska, North Dakota, South Dakota, Texas, and Oregon. Since then it has been abolished by constitutional amendment or other legislation in all but two--Arkansas and Missouri.[2] LEGAL POSITION OF THE ALIEN Thus far, from the point of view of international law and custom, it has been left to each nation to regulate the privileges of, and the restrictions upon, the alien, with the exception that certain nations strong enough to enforce it have established in certain countries held by them to be less than fully “civilized,” the principle of _extra-territoriality_, by virtue of which their nationals must be tried before special tribunals supervised by representatives of their own nation. Generally speaking, and subject to the rule that aliens of all races must be treated alike under processes of law, a nation may deprive the alien of liberty of action, may prohibit or restrict his ownership of property, may forbid or delimit his employment in certain kinds of work or enterprises, and may expel and deport him, at its pleasure. In other words, the status and rights of an alien are determined almost absolutely by the municipal law in the country in which he is domiciled. The only limitations upon this power are those established by treaties, and by the general spread of humane ideas, and the growing feeling--discouraged, perhaps, but by no means halted, by the World War--of the solidarity of the human race.
