The Olympics were organised as a religious festival to honour the leader of the Greek gods, Zeus.
Pierre de Couberrtin, a French educator and historian, thought that if the world countries came together to play sports would bring peace among them, so in 1896, Pierre created the modern Olympic Games in Greece.
They were given olive wreaths as a reward because the leaves were picked from the sacred Olympia olive tree near the temple of the Greek god, Zeus.
I think women weren’t allowed to participate because they wanted to show how strong men were, so by not letting the women to participate, it would show them the strength of a man.
The torch was lit in Olympia (as that was were the olympics originated from) and then passed down to each country until it got to where the olympics where held. On their journey, they are to hold a torch and light a cauldron to symbolise the peace between the countries.
