Vlasta is the Slavic word for "power" or "homeland." In Czech legend, Vlasta was the warrior who led the women in the Maiden's War (Dívčí válka) against the men of Bohemia in the 8th century.
Vlasta is widely used in the Czech Republic.
Vlasta does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Vlasta reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
