English to Arabic Other History

Lincoln's attitude was firm and remarkably consistent throughout the Civil War. He said that succession was simply a myth. It was unconstitutional. The Union was older than the Constitution and the Union was indissolvable.

Also mentioned here:

Despite being torn by succession and civil war, it was a single country again and slavery, the ultimate cause of the war had been banished into memory.

Succession, Lincoln says, is the essence of anarchy. And he is a man who built his whole life on devotion to law, order, to self discipline.

N.B: The text is full of spelling mistakes. Could it be "Secession" as for "الانفصال عن الاتحاد"?
