In the 1800s the term redneck was used to describe farmers who spent many days working in the sun. Wearing hats their heads were protected but it did not protect the back of the neck leaving a red sunburn.
In the 1900s the term was used to identify lower income workers within the political factions inside the democratic party. At this time rednecks were also called wool hat boys simply because richer folks wore expensive silk hats.
By 1910 politicians who were primarily poor farmers began to describe themselves proudly as rednecks and wearing red handkerchiefs around their necks to display the title at political picnics and rallies.
By 1910-1920 American coal miners wore the red handkerchiefs to establish that they were union men wearing it with pride and defiance.
It was not until 1970 when the term morphed into the stereotypical derogatory slag that is most often used today.
So if you are a hard working, hand callous wearing, dirt on your boots person keep history alive and wear a red handkerchief remembering those that came before us.
