Which of the following ended the period of presidential reconstruction?

the election of ulysses s grant in 1868
the assassination of abraham lincoln in 1865
the withdrawal of federal troops from the south in 1877
the radical republicans success in the elections of 1866

The correct answer is "The radical Republicans success in the elections of 1866".

Explanation:

The period of presidential reconstruction started when President Andrew Johnson created a recovery plan after the death of President Abraham Lincoln in 1865. The presidential reconstruction plan included to forgive former Confederates that would like to pledge loyalty to the Union. However the plan did not last long, since radical Republicans gain majority power in the Congress  in the elections of 1866 after several episodes of violence.

the three-fifths compromise was proposed by james wilson and roger sherman, who were both delegates for the constitutional convention of 1787. however, the three-fifth compromise has its roots further back in history, dating back to the continental congress in 1783. the compromise was a result of the apportionment of taxes being related to land values.
