In which period was the Colosseum established?

• A. 1st century B.C.
• B. 2nd century A.D.
• C. 73-75 A.D.
• D. 5th century A.D.

Answer: (C)

The Colosseum’s establishment happens during its construction in the early years of the Flavian dynasty. Work began in the early 70s AD, so the window around 73–75 AD sits right in that active building phase. The amphitheatre wasn’t officially opened until about 80 AD, after the main structure was completed. So this period best matches the time when the Colosseum was being established. The other options are outside the construction period: 1st century BC is before building started, 2nd century AD is after it was already standing, and 5th century AD is long after its completion.
