WORLD HISTORY

Detailed explanation-1: -The fact that the Tiber is navigable as far as the city meant that Rome could be built far enough from the coast as to be practically immune to naval attack or invasion. But before the embankment was built in modern times, the river frequently flooded the many low-lying areas of the city.

Detailed explanation-2: -The Tiber River and the city of Rome are inextricably linked. The Colosseum, Pantheon, and Forum all sat east of the river. Castel Sant’Angelo, the Emperor Hadrian’s family mausoleum, was built directly on the west riverbank. The Tiber provided freshwater for the ancient Romans, their livestock, and their crops.

Detailed explanation-3: -The Tiber was originally called Albula or Albu’la ("white” or “whitish” in Latin) supposedly because the sediment load was so white, but it was renamed Tiberis after Tiberinus, who was an Etruscan king of Alba Longa who drowned in the river.

Detailed explanation-4: -The Tiber flows out of the Apennine Mountains slopes in Emilia-Romagna. A full-flowing mountain river runs through Umbria and Lazio on its way to Rome, joined by the rivers Nera and Aniene.
