Basques

Considered to be Europe's oldest inhabitants, their language, Euskara, is an anomoly - not related to any other known language. It is widely renowned to be the hardest language on Earth. Typical Basque costume includes the compuslory beret (txapela) for men, with a red neckerchief. 
They are widely known in the United States as shepherds. The largest concentrated Basque diaspora population in the US is in Boise, Idaho, followed by Reno, Nevada. 

Traditional activites include improvised singing competitions (bertsolariak), and "strong man" feats of strength.
