Answer:
The correct answers are A and D. As a result of the Emancipation Proclamation, the war became a battle for human rights and freedom, and it opened the door for African Americans to enlist in the Union Army.
Explanation:
The Emancipation Proclamation was an Executive Order proclaimed by President Abraham Lincoln in 1862, that entered into force in 1863 and declared the slaves in rebellious southern states and territories forever free.
The war was a struggle for the preservation of the Union after the southern states had separated. Morale in the south was initially high. People thought they were fighting for his independence and his own way of life. The right of individual states to set their own laws (including the right to keep slaves) was central. Although initially the President of the Union, Lincoln, was also hesitant about the complete abolition of slavery, he changed his mind during the course of the war. He was convinced that slavery had to be abolished in order to win the war. This eventually resulted in the abolition of slavery in the rebellious Confederate States of America, and changed the war from a territorial war to a ideological conflict between abolitionism and slavery.
After the proclamation, the North began to enlist black soldiers. In total, more than 186,000 black soldiers fought along in separate regiments under white officers. Yet the black people in the North were slowly but surely accepted as fellow combatants and human beings.
