Moritz is of German origin, meaning 'morrison' or 'dark sea'. It was popularized by the German poet Christian Morgenstern, whose pen name was 'Moriz'.
The name Moritz experienced significant popularity peaks in the late 20th and early 21st centuries, with notable highs in 1999 (10 births), 2000 (11 births), and 2013 (11 births). However, it has consistently maintained a presence throughout the century, with at least five births recorded every decade since the 1920s.
