Unless you magically skipped world history in school, you’ve probably learned of the biggest ancient cultures over the years. Whether it was the Egyptians, the Greeks and Romans, or the aboriginal peoples of Australia, we know that this world has served as a home to shifting civilizations over the centuries. But while some cultures like those mentioned above tend to get consistent attention, others are lesser-known and are usually limited to academic communities. If you thought you knew about ancient cultures, here are four often-overlooked civilizations to expand your knowledge even further.
Caral Supe

Location: Modern-day Peru
When you think of ancient cultures based in modern Latin America, we usually think of the Inca, Maya, and Aztec civilizations. And maybe if you’re more well-read on the topic, you might know of the Olmec. But the region is rich in distinctive Pre-Columbian civilizations, including the Caral Supe. This culture dates back to 5,000 BCE and is centralized around the Supe River in Peru. The Caral Supe are also known as the Note Chico. So, what makes this civilization so unique?
Even though the culture pre-dates the ceramic age, archeologists were able to find a major site called the Sacred City of Caral-Supe with intact structures that included six massive pyramids, numerous temples, various plazas, and an amphitheater. While the site was first “discovered” by earlier archeologists in 1905, it was left untouched until a 1994 excavation because it didn’t contain gold, silver, or pottery. In fact, those six pyramids are so massive that they were initially mistaken for hills. Today the Sacred City of Caral-Supe is a UNESCO World Heritage Site that you can visit.
Indus/Harappan

Location: Modern-day Pakistan & India
The Indus or Harappan civilization is one of the earliest recorded on the Indian subcontinent. However, not much is known about them since researchers have yet to crack their ancient language to translate any of their writings, drawings, or stone carvings. The culture existed between 3300 and 1600 BCE and occupied a region that stretched between Pakistan and India in the Indus Valley—hence their name.
Even though archeologists and anthropologists have been unable to decipher their language, the Harappan left behind structures that provide clear insight into their capabilities and ingenuity. This culture is best known for its advanced sewage and drainage systems, well-built granaries, and impressive walls. And according to artifacts, the Harappan believed in dentistry, too. So what happened to this culture? Experts believe climate change was the culprit that caused sustained rainfall reduction. This led to population decline as groups left in search of wetter regions.
Sanxingdui

Location: Modern-day China
Ancient cultures can be found nearly anywhere in the world. It can be hard to believe, in some cases, that there could be anything from pre-civilizations to long-standing cultures. But even in a country like China—which has a rich and ancient history—the current culture wasn’t the first. The Sanxingdui is a Bronze Age culture that lived in what is now the Sichuan province of China. So what do we know about this culture? Sadly, aside from beautiful artwork that has been discovered over the years, the Sanxingdui is a bit of an enigma. To date, no written words have ever been found from the archeological sites.
The culture is best known for creating massive carvings out of bronze and intricate engravings on delicate materials like jade. Artifacts from their settlements were first discovered in 1929 with later discoveries in 1986 unearthing eight-foot-tall statues. Experts theorize that geological events led to the settlement’s abandonment somewhere between 1200 to 1100 BCE. Geologic evidence shows that a possible earthquake and landslide took place 2,800 to 3,000 years ago that could have cut off their access to the Minjiang River. But a nearby settlement, Jinsha, features nearly identical artifacts that point to the possibility that the Sanxingdui relocated there.
The Bell-Beakers

Location: Modern-day Europe & northern Africa
Who built Stonehenge? Experts have proof that the Bell-Beakers heavily contributed to creating this unique structure. However, the culture is so obscure that they’re named purely for their most commonly-found artifact—shaped pottery that looks like an upside down bell. The Bell-Beakers are believed to have lived between 2800 and 1800 BCE and occupied lands across Europe from the present-day United Kingdom to the Czech Republic and as far south as northern Africa.
More recent research has shown that the Bell-Beakers weren’t the first people who inhabited the present-day U.K., but they ultimately became the dominant genetic contributors. DNA evidence of prehistoric skeletons reveal that a massive migration occurred over the course of hundreds of years, nearly replacing the previous Neolithic cultures. Present-day Brits have more in common genetically with the Bell-Beakers than the Neolithic peoples.
