Spain found missions and presidios A. to convert American Indians to Christianity, and C. to teach American Indians how to live as Spanish colonist.
It was a way to try that the Indians become sedentarian in the frontier of the Empire. The missionaries often learnt about the Indian culture in order to teach them Christianity in a way they would understand, but it was a non-planned effect of the establishment of missions. I any case they would want the Indians to become soldiers, because they might have turned against them.
The secretary of the post office is not apart of the presidents cabin.
The creation of NATO and the Warsaw Pact shows the dedication to security of the United States and Soviet Union by creating political/military alliances. Both of these organizations formed after World War II give the Soviet Union and the United States peace of mind in case of another war breaking out. The US teamed up with countries like Great Britain, France, and Denmark to create NATO while the Soviet Union aligned themselves with countries like Romania and Albania.
The purpose of treaties between the U.S. Government and Indians was to first of all keep peace between the two and give colonists permission to settle Indian land. Hope this helps!
