The final form of the Emancipation Proclamation (the thing I assume you're asking about) was issued on January 1, 1863, to take effect immediately. Lincoln issued the 'preliminary proclamation' on September 22, 1862, announcing this plan.
In practice, the emancipation took place over time, from this point to the end of the war, as Union armies were able to take control of Confederate territories and free their slaves. (In other cases, the slaves themselves escaped and the Union army was charged with accepting & protecting them, no longer returning them to their former masters.) The last place the Proclamation reached was Texas - on June 19, 1865. This became celebrated as Emancipation Day of "Juneteenth" from then on.
Also to be considered - slaves in Washington D.C. (the only place the federal government could legislate on the subject) were freed by a bill passed and signed in April 1862. It went into effect the day it was signed -- April 16 of that year -- and this date thereafter was recognized as "Emancipation Day" in the district.
Abraham Lincoln was the one.
The preliminary Emancipation Proclamation was written on Sept.22,1862

US President Abraham Lincoln, by the Emanicipation Proclamation issued on 1 January 1863
Yes. Writs of Mandamus were legal documents.
Proclamation, anticipation. Actually, quite a large number -- about 2,000 words -- mainly all words ending with "-ation" (part of a very common suffix).
The Emancipation Proclamation was the proclamation issued by President Lincoln on January 1, 1863, freeing the slaves in those territories still in rebellion against the Union.
Not a sole justification. And it doesn't negate the need to meet all of the other requirements. And it would help if you live in a state that allows emancipation.
Not immediately. But it was the biggest factor in final Union victory, because it had the effect of keeping Britain and France from sending military aid to the Confederates. (It would have made them look pro-slavery.)
Johnson said the rights and guarantees of the Emanicipation Proclamation were sufficient to protect blacks civil rights and a new bill was unnecessary.
The Emanicipation Proclamation was a set of 2 executive orders, written and issued by President Lincoln. It was never read as a speech, to the public at large. He did read it and review it with his cabinet in July of 1862.
