The causes of this jubilation were, however, dangerously diverse; the Abolitionists saw mainly the determination of Lincoln utterly to abolish slavery. This had not been clear before. Lincoln had never been an Abolitionist; he had never believed in full Negro citizenship; he had tried desperately to win the war without Negro soldiers, and he had emancipated the slaves only on account of military necessity. On the other hand, Lincoln learned; he stood now for abolishing slavery forever; he gave full credit and praise to Negro soldiers; and he was soon to face the problem of Negro citizenship.
