You constantly prove what little you know. When I said “eastern part of the states” that includes those states in the eastern part of the country. Those would include N & S Carolina, Georgia, Virginia, Tennessee, Mississippi, and Alabama… Southern States.
One would assume that you would know that the North Eastern States…Massachusetts, Pennsylvania, Rhode Island, NewYork, Vermont, Connecticut, New Hampshire, New Jersey, Delaware, Ohio, Indiana, Maryland, Michigan, Wisconsin, etc had already emancipated their slaves prior to hostilities.
Juneteenth has been observed in Texas for decades prior to YOU ever hearing about it. You obviously know nothing about the subject and even less about Texas.
