公元500年前后，蒂瓦纳库社会政治复杂性的发展是喀喀湖盆地历史上社会变革的主要时期之一。这是前几个世纪在一系列仪式中心发生的人们对过程知之甚少的结果。蒂瓦纳库在这段时间的历史尤其不清楚，因为唯一的放射性碳年代是来自挖掘，其细节从未完全公布。尽管如此，人们一致认为蒂瓦纳库建于公元前300年左右。对这些日期的考古背景重新评估表明，其中许多日期是不可靠的。来自独立发掘的两个贝叶斯模型一致认为，蒂瓦纳库实际上是在几个世纪之后建立的，最有可能是在公元110年左右（50-170,1σ）。这对广泛使用的巨石和陶瓷序列以及理解蒂瓦纳库和其他古代国家的兴起具有重要意义。
The development of sociopolitical complexity at Tiwanaku around AD 500 was one of the major episodes of social change in the history of the Lake Titicaca Basin. It was the result of poorly understood processes that took place at a series of ceremonial centers in the preceding centuries. The history of Tiwanaku during this time is especially unclear, because the only radiocarbon dates are from excavations whose details were never completely published. Despite this, there is consensus that Tiwanaku was founded around 300 BC. A re-evaluation of the archaeological context of each of these dates shows many of them to be unreliable. Two Bayesian models from independent excavations agree that Tiwanaku was in fact founded centuries later, most likely around AD 110 (50-170, 1σ). This has important implications for widely used monolith and ceramic sequences, as well as understanding the rise of Tiwanaku and other archaic states.
