What took lincoln so long to issue the emancipation proclimation

There were several reasons that Lincoln announced and implemented the Emancipation Proclamation at the end of 1862, early 1863. His basic goal was to turn the war from a political focus to a morally based focus. First, Lincoln was in a difficult situation, militarily. The North has lost most of the battles that had been fought, and many Northerners were beginning to grumble about the war.
