Lincoln said: A house divided against itself will not last. What does this mean?

A divided country will not last long. The potentially disastrous consequences of secession were pointed out. Also, the bald eagle that symbolizes the United States on the Great Seal of the United States carries a slogan written in Latin: E Pluribus Unum. So when Lincoln said this, he sincerely wanted the country to unite. At this time, during the Civil War, the South broke away from the Union and declared independence. Lincoln's ability and knowledge made a great contribution to the unity of the country, so Lincoln is also one of the greatest presidents in the eyes of Americans. Under the U.S. Constitution, it is illegal to secede from the Union.
