Like many, I was delighted when President Biden yesterday signed legislation making Juneteenth a federal holiday. June 19th has long marked the day in 1865 when Union troops rode into Texas with the news that “all slaves were free.” Months later the 13th amendment to the Constitution solidified the abolition of slavery in the United States. As Vice-President Kamala Harris noted, national holidays “are days when we as a nation have decided to stop and take stock, and often to acknowledge our history.”
