Tiberius (Tiberius Julius Caesar Augustus, 16 November 42 BC – 16 March 37 AD) was the second Roman Emperor. He ruled from 14 to 37 AD. He was the step-son of Caesar Augustus.
Tiberius was one of Ancient Rome's greatest generals, whose campaigns protected the northern frontier. He reigned for 22 years, and the first part of his imperial work was excellent. Later, he came to be remembered as a dark, reclusive, and somber ruler. After the death of his son Drusus in 23, the quality of his rule declined and ended in terror.
