The Czech name Oldřich is of Slavic origin, composed of two elements: 'Vold' meaning 'famous' and 'Rikjaz/Rych' which signifies 'powerful'. Thus, the full meaning translates to 'powerfully famous' or 'renowned warrior'. The name gained popularity in Bohemia during the Middle Ages due to its association with several prominent historical figures. Oldřich is often shortened to Ota or Otík in everyday use and has seen fluctuations in popularity over time within Czech-speaking communities.
"Oldrich experienced a slight decrease in popularity after its peak in 1917, with no registrations between 1918 and 1921. It then reappeared in 1922."
