Next week we will honor the life, legacy, and accomplishments of Dr. Martin Luther King, Jr. Most notable for his speeches that spoke truth to power, this day was not quickly deemed as a holiday as we see it today. Shortly after his assassination in 1968, the campaign to federally recognize Martin Luther King, Jr. began; however, it was not until 1983 that the holiday was signed into law. Finally, in 2000, all 50 states formally acknowledged and observed the holiday.
