Which best explains why the spanish were able to defeat the aztecs

Well the  spanish had multiple advantages one being that the Aztecs thought he(Hernán Cortés the spanish conquistador that took over the Aztecs)was a literal god and two the spanish were more advanced in civilization

List of all the things the spanish had against the aztecs

1. The Aztecs thought he (Hernán Cortés) was a literal god

2. The spanish had weapons and armor made out of metal

3. The spanish spreaded new sickness to the Aztecs that the Aztecs immune system didn't know so that weekend them making it easier to win the war for the spanish and the sickness also killed a lot of soldiers.

4. They Aztecs had many enemies, the aztecs had many enemies after all they kidnapped people and forced them to pay tribute so anyways the spanish used this against them making allies and a lot more soldiers driven by war for their army. so in a nutshell they used the Aztecs enemies to defeat them.

and that is all I could think of so I hoped this helped.  

as general terms,  indian territory,  the indian territories, or  indian country  describe an evolving land area set aside by the  united states government  for the relocation of  native americans  who held  aboriginal title  to their land. in general, the tribes ceded land they occupied in exchange for  land grants  in 1803. the concept of an indian territory was an outcome of the 18th- and 19th-century policy of  indian removal. after the  civil war(1861–1865), the policy of the government was one of  assimilation.

this is a good question! i'll do some research and come back when i have the answer!
