Final answer:
In 26 AD, Emperor Tiberius moved to the island of Capri, where his rule became increasingly characterized by paranoia and suspicion until his death in 37 AD.
Step-by-step explanation:
In 26 AD, Tiberius permanently moved to the island of Capri, which is situated off of the west coast of Italy. While Tiberius began his rule as a cautionary leader, in time he became increasingly suspicious and temperamental. His residence on Capri became his retreat away from Rome, where he allegedly engaged in nefarious activities and neglected some affairs of state. Tiberius ruled as emperor from 14 AD until his death in 37 AD, and his tenure was marked by various complex issues including political machinations and succession troubles, leading to an atmosphere filled with fear and paranoia.
