He did not free all the enslaved people in the United States because he didn't want to border areas to rebel.
<h3>Why did Lincoln issue the Emancipation Proclamation?</h3>
Lincoln issued the Emancipation Proclamation in order to make the American Civil War about slavery.
This meant that European nations could no longer support the Confederacy because that would have meant that they were supporting slavery. It also boosted support for the war amongst African Americans.
The Emancipation Proclamation did not free the enslaved in the border states because Lincoln did not want them to rebel and in any case he didn't have the Constitutional power to do so.

With this resolution, the US Congress granted the President of the United States -in this case, Lyndon B. Jhonson- unlimited powers to stop communism in Vietnam. After the aggression of two US navy vessels stationed in the Gulf of Tonkin, Congress passed the resolution on August 7, 1964. From this point on, the US Army committed to total support of South Vietnam in the Vietnam War.
