Guns (considered magical, to natives who had never seen them before), metal breastplates and helmets that deflected arrows and spears, and military strategies led to the Spanish conquistador's many successes.
Barbarian tribes
the Spanish were able to defeat the aztecs because of the aztecs own religion because they thought that the spanish ruler was there long lost god and they gave him so much gold that he wanted more and more also because they had swords and guns and they turned to the tribes next to the aztecs for help to the aztecs land.
The Spanish had horses, guns, swords, and cannon while the Aztecs still used hand weapons and spears. They also had the backing from tribes who disliked the Aztecs, such as the Talaxcala. However the defeat of the Aztecs and the downfall of Tenochtitlan was mainly due to the ravages of disease. Most of the population of the Aztec capital, Tenochtitlan, were wiped out by the diseases the Spanish brought, to which the natives had no immunity.
The Spanish had superior weaponry to the Aztecs, and were aided by rival tribes who resented Aztec rule. The primary reason may have been the effect of the diseases spread to the Aztecs by the Spanish. Lacking any immunity to these diseases, many of the Aztecs became seriously ill or died.
The Huns only invaded Persia.
the Aztecs as other native American races were defeated for several reasons: the spanish soldiers had allied with other tribes to defeat them (the tlaxcalls) the spanish soldiers carried diseases that killed many Indians (smallpox) the spanish had technologies that gave them advantage in combat (horses powder and different combat strategies)
Other tribes played a crucial role in the defeat of both the Aztecs and Incas by forming alliances with the Spanish conquistadors. Many indigenous groups resented the dominance and tribute demands of the Aztecs and Incas, which led them to support the Spanish in hopes of overthrowing their oppressors. This collaboration provided the conquistadors with additional manpower and local knowledge, significantly aiding their military campaigns. Additionally, the spread of diseases brought by Europeans weakened the native populations, further facilitating the conquest.
The Aztecs where feared by the Spanish when the Spanish had arrived. This is because they didn't have reinforcements. Also the Chichimec tribes and the Apachean Tribes. NOTE: All of the minor tribes feared them because they didn't have power or good military.
Spanish A+
I think it was the Spanish.
Many Indian tribes fought together to defeat DeSoto's men on iron horses. They killed their horses to put the soldiers on the ground to fight equal and pushed them back to the ocean.
Either India or Lollypop Land.
