What makes it so universally popular is that people all around the world celebrate it because it has an amazing backstory. This has to do with St. Patrick. He grew up to become a bishop and created this parade to celebrate the Irish. In the Brain pop video it says that in the middle of the video it says all the history.

Why would you say he has to use the bathroom in the bucket?

In paragraph 4 it says that he fought for peoples rights for 20 years. I think that you would have to be a real brave man to do that.

He was the first African American in South Africa.

I think the biggest similarities are that they both risked their lives fighting for peoples lives. In paragraph 4 it says that.

Mr. Mandela spent the next 20 years leading peaceful, nonviolent acts of defiance against the racist policies of the South African Government and Martin luther King J was fighting for a civil right aganist the white and the blackIn the winter of 1964, Mr. Mandela was incarcerated to Robben Island, a place that was largely used to isolate political prisoners. Confined to a small cell with no bed and a bucket for a toilet, Mr. Mandela spent his days doing hard labor in a quarry. Martin went jail for almost the same reason.

It sucks that he died because he fought for the Africans' rights for 20 years. He went through a lot. Even though he died he will always be honored. He was the first African American to become a president in South Africa. R.I.P Nelson Mandela.
