Please explain the use of Rome Colosseum in ENGLISH

In brief:
The Colosseum was used to host gladiatorial shows as well as a variety of other events. The shows, called munera, were always given by individuals rather than the state. They had a strong religious element but were also demonstration of power and family prestige, and were immensely popular with the population. Another popular type of show was the animal hunt, or venatio. This utilised a great variety of wild beasts, mainly imported from Africa, and included creatures such as rhinoceros, hippos, elephants, giraffes, lions, panthers, leopards, crocodiles and ostriches. Battles and hunts were often staged amid elaborate sets with movable trees and buildings. Such events were occasionally on a huge scale; Trajan is said to have celebrated his victories in Dacia in 107 with contests involving 11,000 animals and 10,000 gladiators over the course of 123 days.
