Is the lack of cavalry the main reason why the Inca Empire in South America lost to Spanish colonists in history?

The failure of the Inca empire was that the king was captured by the Spanish. After the Inca empire paid the Spanish a huge ransom (gold for a standard house), the Spanish treacherously killed the Inca king.

William Prescott, an American historian, pointed out in his obscure History of the Conquest of Peru that the Inca Empire relied too much on the Inca King and the strength of the people was very weak. Pizarro, a Spanish officer, seized this point, first designed to house arrest the Inca king, and then killed him. So the whole country was in a mess at once, and it was impossible to organize an effective counterattack. According to Spanish memories, when the Spanish army first entered Cuzco, it was unexpectedly discovered that all the people in the city were aliens who immigrated here, except the princes and nobles who lived in the imperial city, and naturally refused to work for the Incas. After the capital was captured, the huge empire collapsed rapidly. Even though the Inca king who succeeded to the throne organized several counterattacks, when the last Inca king was killed, the family lineage of the Inca king was cut off, and the Inca people completely lost their ability to resist. Even if the Spanish colonists exercised very cruel rule over the Indian natives, they could only bear it.

The Inca imperial army was huge, with 70,000 to 80,000 people, but the weapons used were very backward, even behind those used by Europeans in the Middle Ages. At that time, the main weapons of Inca soldiers were sticks, stone axes, javelins, spears, bows and arrows and slingshots (ejecting pebbles). Before the Spanish arrived in the American continent, the Inca Empire was a big country that ruled the western part of South America. At that time, Inca soldiers often marched eastward and fought westward, destroying many tribes in South America and expanding the territory of the empire. Inca soldiers may have enough weapons to deal with small tribes in South America, but when the Spanish arrived in South America, the Inca's military superiority was gone forever.

Dozens of Spanish cavalry units lurking around immediately rushed in the direction of Atahualpa. Although the Inca soldiers were outnumbered, when they saw an unknown animal coming at them, they immediately laid down their weapons and ran away. Spanish cavalry continued to hunt down the escaped Incas, while other Spanish soldiers immediately took Atahualpa off the throne. Thousands of Incas were killed by Spanish cavalry that day.

Inca soldiers were so afraid of horses because they knew nothing about this animal, which gave the Spanish a good chance to destroy the Inca. Moreover, metal is also an important factor. The Incas didn't know much about metals. Metals are often used only for works of art and noble tableware. Moreover, at that time, the Incas were not as good at casting metal as people in the old world, let alone using metal to build good armor or weapons for soldiers. However, the situation in Spain is not like the Incas. Their casting technology is much higher than that of the Incas, and they can make armor for soldiers with metal. So even if Inca soldiers launched fierce attacks on Spanish soldiers at that time, they were often blocked by the metal armor and helmets of Spanish soldiers. On the contrary, Inca soldiers wearing only cloth clothes often could not resist the spears and swords in the hands of Spanish soldiers.

That is to say, the Inca Empire was at a disadvantage from the beginning. To tell the truth, the alpaca cavalry didn't find any relevant records in the history books, and I didn't find any original records. And the Incas are very afraid of horses in historical records, so how can they capture Spanish war horses and form their own cavalry? Moreover, alpacas originally belong to the dromedary, which stands out in the middle. I believe that sitting on it will definitely lead to anal fissure. It is estimated that people will automatically jump off after staggering for a few steps. How can they form an alpaca army?

But if the landlord has more accurate historical data, you can take my words for reference!

Hope to help the landlord!
