Robin and his Merry Men always dressed in green, so they could easily hide in the forest. Robin Hood became a popular hero, because he and his band of outlaws helped ordinary people. When they saw rich people travelling through Sherwood Forest, they used to steal their money and give it to poor people.
Robin's great enemy was the Sheriff of Nottingham. The Sheriff was a cruel and corrupt man. He put high taxes on people and if they couldn't pay the taxes, he threw them into the prison or stole their land.
