Carried into the Slavic world with Byzantine Christianity, the name spread through Kievan Rus’ and remained prominent through devotion to St Alexius (the “Man of God”) and to Metropolitan Alexius of Moscow. It appears in royal and clerical history, notably with Tsar Alexei Mikhailovich and the Romanov heir Tsarevich Alexei; in Ukraine its O‑initial forms gained visibility in the 19th–20th centuries.
