reunifying the country

Explanation:

Lincoln wanted an united America with a single constitution. He wanted the whole country to be free, but still, to be one. In fact, Lincoln cared much more about unifying the country than about slavery, it seems:

"Meu objetivo primordial nesta luta é salvar a União, e não entre resguardar ou destruir a escravidão. Se eu pudesse salvar a União sem libertar qualquer escravo, eu o faria, e se eu pudesse salvá-la libertando a todos, eu o faria!"
