Vasil is of Slavic origin, derived from the Greek 'Basil'. It means 'king' or 'royal', reflecting its association with the ancient Greek royalty and later adopted into Slavic cultures. Vasil was popularized among Eastern European countries through Orthodox Christianity, where it became associated with St. Basil the Great, a 4th-century bishop known for his compassionate works.
"The name Vasil experienced a peak in popularity during the mid-20s with 8 births each year in 1923 and 1924, and an even higher spike of 12 births in 1925. However, it then declined significantly, with only 5 births in 1927 and 1929, and no recorded births between 1926 and 2004. There was a slight resurgence in recent times, with 5 births each in 2005 and 2011."
