在本期播客中，主持人与教授兼军事历史学家赛·谢泼德（Cy Shepard）畅谈了西班牙征服者对阿兹特克和印加帝国令人震惊的征服。这些事件涉及区区几百名征服者在几年内颠覆了拥有数百万人口的庞大帝国，他们常常在兵力处于100比1或1000比1的劣势下赢得战斗，而他们百分之九十九以上的战斗部队由当地盟友组成。 故事始于15世纪，当时欧洲正在寻求通往亚洲的新经济途径。哥伦布向西航行，无意中发现了一个新大陆。1518年，古巴总督德维拉斯奎兹（Governor de Velazquez）指派埃尔南·科尔特斯（Hernan Cortes）探索并深入中美洲。科尔特斯意识到许多当地群体对阿兹特克霸权感到不满。科尔特斯首先与托托纳克人（Totonacs）结盟，随后与拉什卡兰人（Lashkalans）交战至僵局，最终与拉什卡兰人建立了关键的同盟，拉什卡兰人将西班牙人视为摆脱阿兹特克统治的战略机遇。 征服者拥有至关重要的技术和生物优势。钢制铠甲和托莱多钢刃压倒了当地的木制和黑曜石武器，战马则提供了具有恐怖震撼力的骑兵能力，这是当地所没有的。科尔特斯运用心理战、细致的心理施压和外交手段，最终挺进特诺奇蒂特兰（Tenochtitlan）并抓获了阿兹特克皇帝蒙特祖马二世（Moctezuma II）。蒙特祖马被俘打破了他的世界观，使得科尔特斯能够通过他进行统治。当维拉斯奎兹派遣潘菲洛·德·纳尔瓦埃斯（Panfilo de Narvaez）去逮捕科尔特斯时，科尔特斯击败了他，将他的人马收编为增援部队，然后返回首都。在一个下属发动当地大屠杀之后，阿兹特克人发起反抗，导致了“悲伤之夜”（*La Noche Triste*）以及西班牙人的撤退。然而，凭借拉什卡兰人的庇护和新近到达的中美洲盟友，科尔特斯率领军队返回攻占特诺奇蒂特兰，其中征服者仅占总人数的大约百分之零点五，其余则是由寻求结束阿兹特克统治的当地人民组成。 十年后，弗朗西斯科·皮萨罗（Francisco Pizarro）在南美洲针对印加帝国完全复制了同样的策略。皮萨罗在印加内战期间带着168人抵达，于1532年在卡哈马卡战役（Battle of Cajamarca）中俘获了新的萨帕·印加（Sapa Inca）阿塔瓦尔帕（Atahualpa），在那场战役中有数千名印加军队被杀，而征服者零伤亡。后来，曼科·印加（Manco Inca）领导了一场大规模起义并围攻库斯科（Cusco），但最终被站在西班牙人一边的土著派系，以及应对西班牙骑兵和地形优势所需的高昂学习成本所破坏。 除了人为因素外，这些征服还受到宏大历史力量的塑造，特别是天花和其他旧世界疾病，它们摧毁了缺乏获得性免疫的人口。此外，虽然西班牙掠夺了大量的黄金和白银——最终资助了欧洲的战争并为中国的丝绸和瓷器贸易提供资金——但这种轻易得来的财富阻碍了西班牙发展出有效的功能性资本主义，也阻碍了其与英国和荷兰等国家相比进行有效的工业化。 归根结底，阿兹特克帝国和印加帝国之所以脆弱，是因为它们具有集中化的等级社会结构：俘获顶端单一的领导人会使整个系统瘫痪。此外，这些征服展现了无节制的资本主义、灵活的公司组织以及利用长期存在的地区怨恨来分而治之并征服庞大数倍人口的原始力量。

In this episode of the podcast, the host chats with professor and military historian Cy Shepard about the astonishing conquests of the Aztec and Inca empires by Spanish conquistadors. These events involved a few hundred conquistadors subverting massive empires of millions within a matter of years, often winning battles while outnumbered 100x to 1, or 1000x to 1, while upwards of 99% of their fighting forces consisted of native allies. The story begins in the 15th century as Europe seeks new economic avenues to Asia. Columbus heads west and inadvertently finds a new continent. In 1518, Governor de Velazquez of Cuba assigns Hernan Cortes to explore and penetrate Mesoamerica. Cortes realizes that many local groups chafe under Aztec hegemony. Aligning first with the Totonacs and later fighting the Lashkalans to a standstill, Cortes secures a critical alliance with the Lashkalans, who see the Spaniards as a strategic opportunity to break free from Aztec authority. The conquistadors possess vital technological and biological edges. Steel armor and Toledo steel blades overpower native wooden and obsidian weapons, and war horses provide a terrifying shock-and-awe cavalry capability with no native equivalent. Cortes uses mind games, meticulous psychological pressure, and diplomacy, ultimately marching into Tenochtitlan and seizing the Aztec emperor, Moctezuma II. Moctezuma's captivity breaks his worldview, allowing Cortes to govern through him. When Velazquez sends Panfilo de Narvaez to arrest Cortes, Cortes defeats him, absorbs his men as reinforcements, and returns to the capital. Following a local massacre by a subordinate, the Aztecs rebel, leading to *La Noche Triste* and the retreat of the Spanish. However, with Lashkalan shelter and newly arrived Mesoamerican allies, Cortes returns to take Tenochtitlan with a force where conquistadors made up about half of one percent of the total number, while the rest were native people seeking an end to Aztec rule. Ten years later, Francisco Pizarro follows the exact same playbook in South America against the Inca Empire. Arriving with 168 men during an Inca civil war, Pizarro captures the new Sapa Inca, Atahualpa, at the Battle of Cajamarca in 1532, where thousands of Inca troops are killed while the conquistadors suffer zero casualties. Later, Manco Inca leads a massive rebellion and lays siege to Cusco, but is ultimately undermined by indigenous factions siding with the Spanish, along with the steep learning curve required to counter Spanish cavalry and terrain advantages. Beyond human factors, the conquests were shaped by grand historical forces, notably smallpox and other Old World diseases that decimated populations lacking acquired immunity. Furthermore, while the Spanish extracted massive quantities of gold and silver—ultimately funding European wars and financing trade for Chinese silk and porcelain—the easy wealth prevented Spain from developing functional capitalism or industrializing effectively compared to nations like England and the Netherlands. Ultimately, both the Aztec and Inca empires were vulnerable because of their centralized, hierarchical social structures: capturing the single leader at the top crippled the entire system. Moreover, the conquests demonstrate the raw power of unbridled capitalism, flexible corporate organizations, and the exploitation of long-standing regional grievances to divide and conquer vastly larger populations.
