There is a lot of misconception about Juneteenth, the emancipation proclamation, and the 13th amendment.

A little history the emancipation proclamation was effective 1/1/1863, it only affected those areas still in rebellion, not any of the northern states, DC, or any of the southern states under union control. This was an unconstitutional executive order under the fourth amendment seizing property without compensation. But it laid the groundwork for future actions.

Juneteenth, is the celebration of the of General Granger reading General order #3 in Galveston TX. This was the first reading, of many, that occurred freeing the estimated 250,000 enslaved people in Texas. It had the force of law since Texas and the other southern states were under military rule, but could have been reversed once civilian rule was reestablished.

The 13th Amendment (Dec 1865) frees all slaves , but left a loophole.

Section 1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.

Section 2. Congress shall have power to enforce this article by appropriate legislation

True freedom from slavery has eluded a large portion of Americans, black, brown and white, but most don't know it.
