Which of the following was NOT an effect of Union's victory to end the Civil War? 1. Large groups of southerners left the United States to start over in Europe.

2. Slavery was abolished throughout the nation.

3. Federal power went up and state power went down.

4. The country was reunited.

1. Large groups of southerners left the United States to start over in Europe.

Explanation:

Large groups of southerners did in fact leave the US, but they mainly traveled down south (Central America, South America), where slavery was still legal, rather than go to Europe, which in itself had illegalized slavery.

The answer choice is not 2, because slavery was already abolished with the Emancipation Proclamation, in which it's reach to the South occurred following the surrender at Appomattox Court House.

The answer choice is not 3, because President Lincoln actually created and used the Presidential War Powers, which was the founding principal in the President being able to not only go around Congress, but to also suspend people's rights during war time.

The answer choice is not D, because reunification did occur following the Civil War. There was, however, groups of Southerners which continued to resist, as well as the well-known Ku Klux Klan (KKK), which formed shortly after to terrorize the newly freed African slaves, as well as to keep them from being able to use their new found rights, and can be found even up to today's society.
