In British English, 'theatre' means a place where live plays are performed. Some people, both English and American, use the spelling 'theatre' to mean a place where live plays are performed, and the spelling 'theater' to mean a cinema.
The first people we know created plays were the Ancient Greeks, about the year 500 B.C. They divided plays into two kinds: tragedy and comedy. This division is still used today. The best known Ancient Greek writers of plays are Aeschylus, Sophocles, Euripides, and Aristophanes. Some of their plays survived, and are still performed today. These ancient Greek plays were performed outdoors in large amphitheaters so that many people could see them.

In the Middle Ages, the Catholic Church began to use theatre as a way of telling the stories from the Bible to people who did not know how to read. They wrote Mystery Plays, where each part of the Bible story would be a play put on by a different group of people. They wrote miracle plays which were about the lives of the saints. They wrote morality plays which taught the audiences how to live a good Christian life.
At the end of the sixteenth century (before 1600), the traveling actors began to perform in fixed theatre buildings. This was the period when William Shakespeare wrote. He lived from 1564 to 1616.
At that time, in England, women were not allowed to perform, so male actors would play female characters.

His theatre was in London, England. It was called The Globe Theatre. It was an outdoor theatre and plays were performed in the daytime for large audiences. His plays were very popular and many are still performed today. Many people believe Shakespeare was one of the best playwrights (a writer of plays).
Plays including Shakespeare's were banned during the Protectorate' After that, many more were written and acted.

After World War II, playwrights in Europe and the United States began doing plays in a new style called "Theatre of the Absurd." After seeing the horrors of war, these playwrights felt that all their old values had been destroyed.

The Globe, which opened in 1599, became the playhouse where audiences first saw some of Shakespeare's best-known plays. In 1613, it burned to the ground when the roof caught fire during a performance of Shakespeare's Henry VIII. A new, second Globe was quickly built on the same site, opening in 1614.
A theater performance is a beautiful blend of different people from diverse backgrounds coming together. Putting to rest their differences, shedding their inhibitions and perform as one while helping each other. This particular aspect clearly refers to the pillar of diversity.
