Highlights
The Andes Mountains, the world's largest continental mountain range, stretch over 7,000 kilometers across South America. This seismically active region creates extreme landscapes, including the lush Amazon rainforest to the east and the arid Atacama Desert to the west. Despite the harsh conditions, humans have thrived here for millennia, cultivating diverse crops like avocados, peanuts, and potatoes in fertile river valleys.
The Inca were preceded by a series of civilizations in the Andes, with the Moche and Nazca being prominent examples. These societies, flourishing between 400 BC and 580 AD, developed advanced irrigation systems in the Atacama Desert. The Nazca are particularly famous for their colossal geoglyphs, intricate patterns and images etched into the desert landscape, whose purpose remains a subject of debate.
In 1911, Hiram Bingham, a young explorer, searched for a rumored lost city in the Peruvian Andes. Following a local guide's tip, he ascended a difficult mountain trail and discovered a vast complex of ancient Inca ruins, later identified as Machu Picchu. Bingham was awestruck by the sophisticated stonework and numerous structures, realizing he had stumbled upon a significant historical site, an abandoned royal estate of the Inca people.
Paul Cooper introduces The Fall of Civilizations podcast, aiming to explore the Inca Empire. He intends to delve into how this unique culture thrived in the extreme Andean mountains, built the largest empire in the Western Hemisphere, and ultimately met a dramatic end.
Life in the high Andes was exceptionally challenging, with limited arable land and extreme altitudes. Andean people adapted by dividing their landscape into distinct zones for different crops and livestock (llamas, alpacas, guinea pigs). The difficult environment fostered a reciprocal economy and collective labor, essential for survival and large-scale projects like irrigation and terrace farming. Infant mortality was high, leading to practices like delayed naming for children.
Tiwanaku, one of the first great cities of the Andes, emerged near Lake Titicaca in modern-day Bolivia. It featured impressive pyramid structures and carved stone gateways, with blocks weighing up to 66 tons. In Inca mythology, Tiwanaku was the place where the creator god Viracocha brought light and life to the world. Although a ruin by the time of the Inca, its architectural and cultural influence, particularly in stone carving, was profound.
The Wari were masters of water control, building extensive aqueducts to irrigate coastal plains and transform the Andean landscape. Though their architecture was less ornate than Tiwanaku, their structures were massive and strategically built. The Wari embarked on rapid expansions, potentially driven by new religious beliefs or climate change, integrating diverse populations and building terraces to cultivate food in high altitudes. Moray, a site with circular terraces, served as a laboratory for developing resilient crop strains. Their empire lasted over 400 years before its decline around 1000 AD, leaving a power vacuum and a legacy of administrative empire-building that the Inca would draw upon.
The Inca lacked a written language, relying on a system of knotted ropes called quipus for record-keeping and transmitting information. The exact meaning and method of decoding quipus are lost to modern times. Our understanding of Inca history primarily comes from European accounts: eyewitness Spanish chronicles, post-conquest writings by Europeans, and later accounts by native authors trained in Spanish. These sources are fraught with biases, making accurate interpretation challenging but nevertheless crucial for reconstructing the Inca narrative.
Inca history, according to their own legends, began with a small band of highlanders settling in Cusco, a fertile valley in the southern Peruvian highlands around 1200 AD. Early structures were humble, made of rough stones and thatched with ichu grass. Cusco's location, at the crossroads of earlier empires, fostered a hybrid culture. Inca origin myths include tales of four brothers emerging from a cave and a migration from Lake Titicaca, all emphasizing a destiny to expand and bring civilization.
The Inca credit their rapid expansion to Emperor Pachacuti Inca Yupanqui, whose name means 'He who overturns time and space.' Though he wasn't destined for the throne, Pachacuti rose to power after defending Cusco against the Chanka invasion. He rebuilt Cusco, transforming it into an imperial capital, and initiated an astonishing series of military victories. Pachacuti also oversaw massive infrastructure projects, including an extensive road system that allowed for swift troop movement and administration. His reign expanded the empire significantly, cementing the Inca's dominance through a blend of military might, strategic diplomacy, and grand construction.
Pachacuti's expansion tactics included both ruthless resettlement of non-compliant populations and diplomatic engagement, offering luxurious gifts to persuade neighboring rulers to join the empire. Refusal led to invasion, and resistant leaders were executed. The Inca army, composed of conscripted commoners, could number up to 140,000 and relied on sheer force and effective logistics. Storehouses (qullqas) were strategically positioned across the empire to supply the army and convey messages of Inca provision. The Inca also adopted an inclusive religious policy, absorbing local gods into their pantheon, which facilitated the integration of diverse peoples into their vast realm, exemplified by their embrace of the Huarochiri god Maca Uisa and the oracle of Pacha Kamaq.
Machu Picchu, a royal estate built by Pachacuti around 1440 AD, showcases Inca engineering atop a mountain ridge. Its purpose, possibly a royal retreat or trading post for coca leaves, remains debated. The city's intricate steps, water systems, and temples illustrate Inca architectural and agricultural prowess. Pachacuti's reign culminated in the reorganization of the kingdom into Tahuantinsuyu, 'the realm of the four parts,' with Cusco as its central hub. The empire, encompassing up to 12 million people across two million square kilometers, was a marvel of administration and coordination, particularly given its vertical rather than horizontal expansion across diverse climates.
The Inca economy was highly centralized, featuring shared ownership and collective labor (mit'a). Private property was nonexistent; families received land and llamas from the state, contributing surplus food and labor in return. Nobles and high officials were exempt from mit'a. Cloth was a vital resource, primarily produced by women. The strict hierarchy limited commoners' independence, with authorities monitoring personal wealth. This complex system was managed without a written language, relying on quipus to store vast amounts of demographic and economic data. At its peak, the Inca Empire represented a highly organized and confident civilization.
Around 1500 AD, as Emperor Huayna Capac returned to Cusco after a jungle campaign, the empire was in mourning for his mother. Unbeknownst to the Inca, across the Atlantic, Europe was also experiencing a momentous period, marking a millennium and a half since Christ's birth. Fears of apocalyptic events mingled with the expansion of European powers into the New World. While Europe marked a new millennium, the Inca Empire was unknowingly nearing a devastating encounter with these external forces, an event that would ultimately lead to its collapse.
Emperor Huayna Capac, 'the young mighty one,' reigned from 1493, constantly expanding the Inca Empire into present-day Chile, Argentina, and north into Ecuador and Colombia. These northern jungle wars were long and arduous, draining the empire's resources. While campaigning, he likely heard rumors of mysterious strangers and a devastating plague. In 1527, Huayna Capac died suddenly of this unknown disease, leaving a prophecy of impending doom. His death initiated a succession crisis, compounded by the plague that decimated Cusco, setting the stage for a brutal civil war between his sons, Huascar and Atahualpa.
Huayna Capac's death left the empire vulnerable. His son, Huascar, declared himself ruler in Cusco, while Atahualpa, another son, commanded a significant army in the northern region of Quito. This division led to a five-year stalemate that culminated in a brutal civil war. Atahualpa, a fierce commander, proved ruthless in his campaign, massacring inhabitants of Tumebamba and showing no mercy to those who opposed him. His battle-hardened troops defeated Huascar's forces at the Plains of Quipaypan, capturing Huascar and effectively bringing an end to the established order. Atahualpa intended to move the capital to Quito, unaware that a new external threat had already landed, poised to exploit the empire's internal strife and conquer its lands.
