the collapse of the mayan empire is believed to have occurred during
Classic Maya collapse In archaeology, the classic Maya collapse is the decline of Classic Maya civilization and the abandonment of Maya cities in the southern Maya lowlands of Mesoamerica between the 8th and 9thÂ centuries, at the end of the Classic Maya Period. Preclassic Maya experienced a similar collapse in the 2nd century.[citation needed]
Fall of the Western Roman Empire Relevant dates include 117 CE, when the Empire was at its greatest territorial extent, and the accession of Diocletian in 284. Irreversible major territorial loss, however, began in 376 with a large-scale irruption of Goths and others. In 395, after winning two destructive civil wars, Theodosius I died, leaving a collapsing field army and the Empire, still plagued by Goths, divided between his two incapable sons. By 476 when Odoacer deposed the Emperor Romulus, the Western Roman Emperor wielded negligible military, political, or financial power and had no effective control over the scattered Western domains that could still be described as Roman. Invading barbarians had established their own power in most of the area of the Western Empire. While its legitimacy lasted for centuries longer and its cultural influence remains today, the Western Empire never had the strength to rise again.
