Roman Empire was established in 27 BCE following the ending of the Roman Republic and continuing to the final demise of the Empire of the West in the 5th century CE.
The influence of the Roman Empire was profound in shaping all aspects of society for centuries. Its trade with Asia via the Silk Road established cross-cultural exchanges that continue to today.
Pompeii, an ancient Roman city in southwestern Italy, on the Bay of Naples, was buried beneath volcanic ash when Mount Vesuvius erupted in the year 79. It disappeared as if the city had never existed until its rediscovery in 1748.
When a volcano is erupting, red-hot liquid rock called lava spews from the top; ash and poison gases are released.
Mount Vesuvius is an active volcano that rises above the Bay of Naples on the plain of Campania in southern Italy. The eruption of Vesuvius in the year 79 was destructive, burying the city of Pompeii.
