Josua is of Hebrew origin, translating to 'God is salvation'. This name has been prominent throughout history, notably appearing in the Bible as a key figure in the conquest of Canaan. It gained popularity among Christians during the Middle Ages and was subsequently used across Europe.
"The name Josua experienced a significant rise in popularity between the late 1970s and mid-1980s, with peaks of 33 births in 1983 and 48 births in 1985. However, it has since declined, with fewer than 20 births per year since 2006, and consistently five births per year from 2013 onwards."
