Vyacheslav is a Slavic male given name of Old Russian origin. It means 'more glory' and is composed of two elements: 'vyache', meaning 'more', and 'slav', meaning 'glory'. The name was particularly popular during the Middle Ages in Russia, often borne by noblemen and warriors due to its strong, powerful sound.
"Vyacheslav saw a spike in births between 2010 and 2013, with a total of 16 babies born over the period."
