Step 1 : Introduction to the question "Who are the "People of the Veil?""
...The Tuaregs have a population of around 2 million spread across Saharan Africa in southeastern Algeria, southwestern Libya, northern Burkina Faso and other places. Tuaregs are often called the "People of the Veil" because the men begin around age 25 to wear veils that cover the face completely except for the eyes. This is done to ward off evil spirits that could enter the body through the mouth or nose. Source: WorldAtlas.com
