The National Association for Stock Car Auto Racing (NASCAR) is a family-owned and -operated business venture that sanctions and governs multiple auto racing sports events. It was founded by Bill France Sr. in 1947–48. As of 2009, the CEO for the company is Brian France, grandson of Bill France Sr. NASCAR is the largest sanctioning body of stock car racing in the United States. The three largest racing series sanctioned by NASCAR are the Sprint Cup Series, the Nationwide Series, and the Camping World Truck Series. It also oversees NASCAR Local Racing, the Whelen Modified Tour, the Whelen All-American Series, and the NASCAR iRacing.com Series. NASCAR sanctions over 1500 races at over 100 tracks in 39 US states and Canada. NASCAR has presented exhibition races at the Suzuka and Motegi circuits in Japan, Mexico, and Calder Park Raceway in Australia.

NASCAR's headquarters are located in Daytona Beach, Florida, although it also maintains offices in four North Carolina cities: Charlotte, Mooresville, Concord, and Conover. Regional offices are also located in New York City, Los Angeles, Bentonville, Arkansas, and international offices in Mexico City and Toronto. Additionally, owing to its Southern roots, all but a handful of NASCAR teams are still based in North Carolina, especially near Charlotte.

The Irish people (Irish: Muintir na hÉireann or na hÉireannaigh; Ulster-Scots: Airisch or Airish fowk) are an ethnic group who originate in Ireland, an island in northwestern Europe. Ireland has been populated for around 9,000 years (according to archaeological studies, see Prehistoric Ireland). The Irish people's earliest ancestors are recorded in legends – they are claimed to be descended from groups such as the Nemedians, Fomorians, Fir Bolg, Tuatha Dé Danann and the Milesians.Lebor Gabála Érenn, a book of Irish mythology tells that Tuatha Dé Dananns were Scythian descendants.

The main groups that interacted with the Irish in the Middle Ages include the Picts, Scots, and the Vikings. Due to this contact, Icelanders are noted for having some Irish descent. The Anglo-Norman invasion of the High Middle Ages, the English plantations and the subsequent English rule of the country introduced the Normans and Flemish into Ireland. Welsh, Picts, Bretons, and small parties of Gauls and even Anglo-Saxons are known in Ireland from much earlier times.
