The Natives had a good relationship with the United States and was able to get more materials through trade with the Americans
”The United States being also anxious that the Great and Little Osage, resident as aforesaid, should be regularly supplied with every species of merchandise, which their comfort may hereafter require, do engage to establish at this place, and permanently to continue at all seasons of the year, a well assorted store of goods, for the purpose of bartering with them on moderate terms for their peltries and furs” (“Treaty with the Osage”).
In the treaty with a native tribe called the Osage, it is told that the Americans supplied the Natives with plenty of resources and merchandise. The tribe was supplied with comfort that they would need. The U.S promised to keep their trading post up at the location year round, trading goods for their goods like peltries and furs on controlled rates. This means that the Osage and most likely other native tribes were affected by the purchase by gaining peace and friendship with the Americans by being provided things they needed like comfort and merchandise and they were also able to trade their goods with American goods so they could get other goods that they needed.
The Americans were satisfied with the purchase and they gained a more valuable market for trading states.
”the jurisdiction of the territory as now transferred to our hands and in future the navigation of the Mississippi will be ours unmolested. This, it will be allowed is an important acquisition; not, indeed, as territory, but as being essential to the peace and prosperity of our Western country, and as opening a free and valuable market to our commercial states. This purchase has been made during the period of Mr. Jefferson’s presidency, and will, doubtless, give eclat to his administration” (Hamilton).
In the newspaper, it is stated that the gain of the territory was a good thing, and that it would keep up with the peace and prosperity of the western regions. The Mississippi River will now be free to be navigated without interference and that it would open a market to commercial states that was free and valuable. It was also said that the current president, Jefferson, would gain great credit and recognition to his administration because of the purchase. This means that the Americans reacted positively towards the purchase and that they were affected by gaining a free and valuable market and peace in the western areas.
