Lincoln's assassination put the future of the nation in question because he was seen as a unifying force in the aftermath of the Civil War, and his death left a power vacuum that could have been filled by more extremist voices. Additionally, there were concerns about how his successor, Andrew Johnson, would handle the delicate process of Reconstruction and rebuilding the country.
Of course Lincoln planned to exile all black people in the US to a new country he would establish in Africa. I wonder how that would have worked out.
It is true that Lincoln had proposed a plan to resettle some freed slaves to Central America or Africa, but it was only one of his many ideas to address the issue of slavery and race in America. The plan was never realized and there is much debate among historians as to what Lincoln's true intentions were with this proposal. However, it is important to note that Lincoln was also committed to the principles of equality and freedom for all Americans, and his Emancipation Proclamation was a key step in ending slavery in the United States.
Lincoln's assassination put the future of the nation in question for several reasons. Firstly, his assassination left a leadership void and uncertainty about who would assume the presidency and guide the nation through the post-Civil War reconstruction period. Additionally, it intensified tensions between the North and the South, as many Southern sympathizers viewed the act as a retaliation for their defeat in the war and a potential spark for renewed conflict.
