Who is first african american president
Marina CMI [18]

Answer:

First ever black president John Hanson.   first american black president  Barrack Obama.

Explanatin:

Someone that I know has been posting that Barack Obama is not the first African-American President, that indeed there was an African-American President before him, John Hanson.

I did my own research and found that John Hanson was the President of the Constitutional Congress, something quite different than the President of the United States (considering the United States wasn't even formed then). I also found that the John Hanson that was the President of the Constitutional Congress was not African, he was indeed Swedish.

I have found web sites that claim there is a cover-up about John Hanson and say that he was an African and that history has been changed to make him appear white. They have a photo of a man that they claim to be him. However, I don't believe these claims. I don't know who the man in the photos is, but I do know that there was a John Hanson who lived a hundred years after the John Hanson that I'm looking for, he was from Liberia and African—but NOT the president of the Constitutional Congress.

Answer

John Hanson, who held the office that was known officially as "President of the United States in Congress Assembled" from November 5, 1781 to November 4, 1782, died in November 1783 long before the invention of photography. The African-American man in the photograph that you saw on a website could not have been this John Hanson.

Why were congressional republicans angry that southern legislatures passed laws known as black cord
kogti [31]
Republicans were angry that southern legislatures passed laws known as "black codes" because the Republicans had fought to eliminate slavery and give equal rights to the freed African Americans, and the black codes severely limited the rights of these newly-freed slaves.
