His father did not let him go outside the palace because according to a prophecy to a reasonable man he had to stay home so that he could become a world ruler also because his father did not want him to see suffering.
Finally, when he was 29 years old he decided to go out and see the world.He saw the suffering of the people.

After 29 days of severe mediation...
He found the answer to his question then he was called Buddha, the enlightened one.
