Question

what was not an impact of the emancipation proclamation?
recruiting blacks into the military
eliminating lawful slavery in certain areas
allowing black property holders to vote
changing the meaning of the war

Explanation:

The Emancipation Proclamation was mainly about freeing slaves in certain areas (eliminating lawful slavery in those regions), it also led to recruiting blacks into the military as the war's nature (changing the meaning of the war) shifted towards a fight for freedom. But it did not address the right to vote for black property holders. Voting rights for African - Americans came later with other legislation like the 15th Amendment.

Answer:

allowing black property holders to vote
