President Andrew Jackson, who died 16 years before the Civil War started, saw it coming and was angry. Would never have let it happen! — Donald J. Trump (@realDonaldTrump) May 2, 2017

US President Donald Trump doesn’t seem to be careful about his lack of knowledge as he appeared confused about why the American Civil War happened in the first place.The businessman-cum-president commented that former US President Andrew Jackson was “really angry” about the war which took place 16 years after his death.Not only that, Trump also went on to say Jackson, who had owned slaves and launched a campaign against Native Americans, had a “big heart”.The US president made these remarks in an interview marking his 100th day in office about which he said it was a very intensive process for him.“Really intense. I get up to bed late and I get up early,” Trump said.The topic of the civil war started when Trump started discussing a painting of the seventh US president that Trump moved into his office.“He was really angry that he saw what was happening with regard to the civil war. He said, ‘There’s no reason for this.’ People don’t realise, you know, the civil war – if you think about it, why? People don’t ask that question, but why was there a civil war? Why could that one not have been worked out?” Trump said in the interview.The American Civil War was started in 1861 over slavery of African-Americans after Jackson died in 1845.Later on, the US president tried clarifying his remarks by tweeting that Jackson had actually ‘seen the war coming and was really angry about it’.Many Americans expressed their disbelief over Trump’s comments and said the civil war was an epoch in the US history.“Footnote for non-US readers,” said a professor of American literature at the University of London. “There are probably as many books about the origins of our Civil War as about the origins of World War II.”The article originally appeared on The Guardian
