97 U.S. 566 (____)
COOK
v.
PENNSYLVANIA.
Supreme Court of United States.

*567 Mr. Benjamin Harris Brewster for the plaintiff in error.
Mr. Lyman D. Gilbert, Deputy Attorney-General of Pennsylvania, contra.
*569 MR. JUSTICE MILLER delivered the opinion of the court.
The act of the legislature of Pennsylvania, of May 20, 1853 (Pamphlet Laws, 683), declares that 
"The State duty to be paid on sales by auction in the counties of Philadelphia and Allegheny shall be on all domestic articles and groceries, one-half of one per cent; on foreign drugs, glass, earthenware, hides, marble-work, and dye-woods, three-quarters of one per cent."
By the sixth section of the act of April 9, 1859, the law was modified, as follows: 
"Said auctioneers shall pay into the treasury of the Commonwealth a tax or duty of one-fourth of one per cent on all sales of loans or stocks, and shall also pay into the treasury aforesaid a tax or duty, as required by existing laws, on all other sales to be made as aforesaid, except on groceries, goods, wares, and merchandise of American growth or manufacture, real estate, shipping, or live-stock; and it shall be the duty of the auctioneer having charge of such sales to collect and pay over to the State treasurer the said duty or tax, and give a true and correct account of the same quarterly, under oath or affirmation, in the form now required by law." Pamphlet Laws, 436.
The effect of this legislation is, that by the first statute a discrimination of one-fourth of one per cent is made against *570 foreign goods sold at auction; and by the last statute, while all sales of foreign or imported goods are taxed, those arising from groceries, goods, wares, and merchandise of American growth or manufacture are exempt from such tax.
It appears that the law also required these auctioneers to take out a license, to make report of such sales, and to pay into the treasury the taxes on these sales.
The defendant refused to pay the tax for which he was liable under this law, for the sale of goods which had been imported and which he had sold for the importers in the original packages. In the suit, in which judgment was rendered against him in the Supreme Court of Pennsylvania, he defended himself on the ground that these statutes were void, because forbidden by sects. 8 and 10 of art. 1 of the Constitution of the United States.
The clauses referred to are those which give to Congress power to regulate commerce with foreign nations, and forbid a State, without the consent of Congress, to levy any imposts or duties on imports. The case stated shows that the goods sold by defendant were imported goods, and that they were sold by him in the packages in which they were originally imported. It is conceded by the Attorney-General of the State, that if the statute we have recited is a tax on these imports, it is justly obnoxious to the objection taken to it.
But it is argued that the authority of the auctioneer to make any sales is derived from the State, and that the State can, therefore, impose upon him a tax for the privilege conferred, and that the mode adopted by the statute of measuring that tax is within the power of the State. That being a tax on him for the right or privilege to sell at auction, it is not a tax on the article sold, but the amount of the sales made by him is made the measure of the tax on that privilege. In support of this view, it is said that the importer could himself have made sale of his goods without subjecting the sale to the tax. The argument is fallacious, because without an auctioneer's license he could not have sold at auction even his own goods. If he had procured, or could have procured, a license, he would then have been subject by the statute to the tax, for it makes no exception. By the express language of the statute, the auctioneer *571 is to collect this tax and pay it into the treasury. From whom is he to collect it if not from the owner of the goods? If the tax was intended to be levied on the auctioneer, he would not have been required first to collect it and then pay it over. It was, then, a tax on the privilege of selling foreign goods at auction, for such goods could only be sold at auction by paying the tax on the amount of the sales.
The question as thus stated has long ago and frequently been decided by this court.
In Passenger Cases (7 How. 283), a statute of New York was the subject of consideration, which required an officer of the city of New York, called the health commissioner, to collect from the master of every vessel from a foreign port, for himself and each cabin passenger on board his vessel, one dollar and fifty cents, and for each steerage passenger, mate, sailor, or mariner, one dollar. A statute of the State of Massachusetts was also considered, which enacted that no alien passengers (other than certain diseased persons and paupers, provided for in a previous section) should be permitted to land until the master, owner, consignee, or agent of such vessel should pay to the regularly appointed boarding officers the sum of two dollars for each passenger so landing. In both instances, although the master or the owner of the vessel was made to pay the sum demanded, it was held to be a tax on the passengers. It was he whose loss it was when paid, and the burden rested ultimately and solely on him. Mr. Chief Justice Taney says: "It is demanded of the captain, and not from every separate passenger, for the convenience of collection. But the burden evidently falls on the passenger, and he, in fact, pays it, either in the enhanced price of his passage, or directly to the captain, before he is allowed to embark for the voyage." Because it was such a tax, the majority of the court held it to be unconstitutional and void.
In the case of Crandall v. State of Nevada (6 Wall. 35), the State had passed a law requiring those in charge of all the stage-coaches and railroads doing business in the State to make report of every passenger who passed through the State or went out of it by their conveyances, and to pay a tax of one dollar for every such passenger. The argument was urged *572 there, that the tax was laid on the business of the railroad and stage-coach companies, and the sum of one dollar exacted for each passenger was only a mode of measuring the business to be taxed. But the court said, as in Passenger Cases, that it was a tax which must fall on the passenger, and be paid by him for the privilege of riding through the State by the usual vehicles of travel.
In Case of the State Freight Tax (15 id. 232), Mr. Justice Strong says: "The case presents the question whether the statute in question  so far as it imposes a tax upon freight taken up within the State and carried out of it, or taken up outside the State and delivered within it, or, in different words, upon all freight other than that taken up and delivered within the State  is not repugnant to the provision of the Constitution of the United States." It was argued here again that the tax was one on the business and franchises of the railroad companies which were required to pay it; but the court, reviewing the authorities, said that the inquiry was upon what did the burden really rest, and not upon the question from whom the State exacted payment into its treasury. This language was abundantly supported by the cases concerning tax on the national banks; namely, Bank of Commerce v. New York City, 2 Black, 620; Bank Tax Cases, 2 Wall. 200; Society for Savings v. Coite, 6 id. 594; Provident Institution v. Massachusetts, id. 611.
In Henderson v. The Mayor (92 U.S. 259), where the owners of vessels from a foreign port were required to give a bond, as security, that every passenger whom they landed should not become a burden on the State, or pay for every such passenger a fixed sum, it was held to be in effect a tax of that sum on the passenger, however disguised by the alternative of a bond which would never be given. The court said, that "in whatever language a statute may be framed, its purpose must be determined by its natural and reasonable effect; and if it is apparent that the object of this statute, as judged by that criterion, is to compel the owners of vessels to pay a sum of money for every passenger brought by them from a foreign shore and landed at the port of New York, it is as much a tax on passengers, if collected from them, or a tax on *573 the vessel or owner for the exercise of the right of landing their passengers in that city, as was the statute held void in the Passenger Cases."
To the same effect, and probably more directly in point, is the case of Welton v. State of Missouri (91 id. 275), decided in the same term. In that case, pedlers were required, under a severe penalty, to take out a license; and those only were held to be pedlers who dealt in goods, wares, and merchandise which were not of the growth, produce, or manufacture of the State. The court, after referring to the case of Brown v. Maryland, relied on by defendant here, adds: "So, in like manner, the license tax exacted by the State of Missouri from dealers in goods which are not the product or manufacture of the State, before they can be sold from place to place within the State, must be regarded as a tax upon such goods themselves; and the question presented is, whether legislation, thus discriminating against the products of other States in the conditions of their sale by a certain class of dealers, is valid under the Constitution of the United States." And it was decided that it was not. See also Waring v. The Mayor, 8 Wall. 110.
The tax on sales made by an auctioneer is a tax on the goods sold, within the terms of this last decision, and, indeed, within all the cases cited; and when applied to foreign goods sold in the original packages of the importer, before they have become incorporated into the general property of the country, the law imposing such tax is void as laying a duty on imports.
In Woodruff v. Parham (8 Wall. 123) and Hinson v. Lott (id. 148), it was held that a tax laid by a law of the State in such a manner as to discriminate unfavorably against goods which were the product or manufacture of another State, was a regulation of commerce between the States, forbidden by the Constitution of the United States. The doctrine is reasserted in the case of Welton v. State of Missouri, supra. The Congress of the United States is granted the power to regulate commerce with foreign nations in precisely the same language as it is that among the States. If a tax assessed by a State injuriously discriminating against the products of a State of the Union is forbidden by the Constitution, a similar tax against goods imported from a foreign State is equally forbidden.
*574 A careful reader of the history of the times which immediately preceded the assembling of the convention that framed the American Constitution cannot fail to discover that the need of some equitable and just regulation of commerce was among the most influential causes which led to its meeting. States having fine harbors imposed unlimited tax on all goods reaching the Continent through their ports. The ports of Boston and New York were far behind Newport, in the State of Rhode Island, in the value of their imports; and that small State was paying all the expenses of her government by the duties levied on the goods landed at her principal port. And so reluctant was she to give up this advantage, that she refused for nearly three years after the other twelve original States had ratified the Constitution, to give it her assent.
In granting to Congress the right to regulate commerce with foreign nations, and among the several States, and with the Indian tribes, and in forbidding the States without the consent of that body to levy any tax on imports, the framers of the Constitution believed that they had sufficiently guarded against the dangers of any taxation by the States which would interfere with the freest interchange of commodities among the people of the different States, and by the people of the States with citizens and subjects of foreign governments.
The numerous cases in which this court has been called on to declare void statutes of the States which in various ways have sought to violate this salutary restriction, show the necessity and value of the constitutional provision. If certain States could exercise the unlimited power of taxing all the merchandise which passes from the port of New York through those States to the consumers in the great West, or could tax  as has been done until recently  every person who sought the seaboard through the railroads within their jurisdiction, the Constitution would have failed to effect one of the most important purposes for which it was adopted.
A striking instance of the evil and its cure is to be seen in the recent history of the States now composing the German Empire. A few years ago they were independent States, which, though lying contiguous, speaking a common language, and belonging to a common race, were yet without a common government.
*575 The number and variety of their systems of taxation and lines of territorial division necessitating customs officials at every step the traveller took or merchandise was transported, became so intolerable, that a commercial, though not a political union was organized, called the German Zollverein. The great value of this became so apparent, and the community of interest so strongly felt in regard to commerce and traffic, that the first appropriate occasion was used by these numerous principalities to organize the common political government now known as the German Empire.
While there is, perhaps, no special obligation on this court to defend the wisdom of the Constitution of the United States, there is the duty to ascertain the purpose of its provisions, and to give them full effect when called on by a proper case to do so.
The judgment of the Supreme Court of Pennsylvania will be reversed, and the case remanded for further proceedings, in conformity with this opinion; and it is
So ordered.
