Answer:
The primary reason that Native Americans were unable to defeat the Spanish conquistadors was disease. The Spanish brought with them diseases such as smallpox to which Native Americans had never been exposed and thus had no immunity.
Step-by-step explanation:
The Natives came to believe that the Spanish “had not their Mission from Heaven” because the Spanish so cruelly treated the Indians. The Indians saw them as evil. During the Spanish-American War (1898), Native Americans served in the First Territorial Volunteer Infantry and, most famously, the First Volunteer Cavalry, also known as the Rough Riders. On December 29, 1890, near the Wounded Knee Creek in South Dakota, U.S. troops fired at the Indians, killing and injuring more than 350 people according to the U.S. Congressional Record. After the Wounded Knee Massacre, armed Indian resistance was largely suppressed. The Spanish were able to defeat the Aztecs and the Incas not only because they had horses, dogs, guns, and swords, but also because they brought with them germs that made many native Americans sick. Diseases like smallpox and measles were unknown among the natives; therefore, they had no immunity to them. The Spanish invaded the Native lands for three main reasons: a lust for glorious battle; the desire to convert people they considered to be heathen savages; and gold or the wealth from the exploitation of Indigenous land and labour. Native Americans resisted change brought by contact with Europeans in the same period by waging war with the Europeans in order to preserve their culture. Some Native Americans also resisted change by refusing to convert to Christianity and instead kept their traditional religion.
