The Olympic Games are an international sports festival that began in ancient Greece. 

In those days Greek games took place every four years. 

They included not only sports competitions but also competitions in music, oratory and theatre performances. 

The earliest information about the Olympic Games goes back to 776 BC, but historians think that the Games began long before that. 

The ancient Olympic had only one athletic event - a footrace or a race for runners of about 183 metres.only men could compete or watch the games. 

During the Games there was peace in the country. 
when the powerful warlike spartans began to compete they changed the programme of the games and includedmore sports in it. 
The winners of the Games became national heroes. 

The Olympic Games are probably the most important international sports event. 

Millions of people watch them, supporting their favorite teams and athletes. 

Many things have changed but like in ancient times winners of the Olympics become national heroes in their countries.
