As an AI language model, I do not have personal opinions or beliefs, but here are five interesting facts about May 19 in Mississippi history:

1. In 1964, civil rights activists Michael Schwerner, James Chaney, and Andrew Goodman were arrested in Neshoba County, Mississippi, while investigating the burning of a black church. They were later released and subsequently kidnapped and murdered by members of the Ku Klux Klan, becoming known as the "Mississippi Burning" case.

2. On May 19, 1943, one of the deadliest tornadoes in Mississippi history struck the city of Tupelo, killing 216 people and injuring over 700. The storm destroyed over 500 homes and businesses, leaving thousands homeless.

3. In 1828, the Mississippi State Capitol building was completed and officially dedicated on May 19. The state's legislature continued to meet in the building until 1903, when it was deemed too small and replaced with the current capitol building.

4. On May 19, 1863, Confederate General John C. Pemberton arrived in Vicksburg to take command of the Confederate forces defending the city. Pemberton's troops would ultimately surrender to Union forces led by General Ulysses S. Grant on July 4, 1863, ending the Siege of Vicksburg and splitting the Confederacy in two.

5. On May 19, 2003, the United States Supreme Court ruled in the case of Lawrence v. Texas that laws criminalizing consensual same-sex sexual conduct were unconstitutional. The case originated in Texas but had implications for Mississippi and other states with similar laws.
