Kubaba (also Ku-Baba, 𒆬𒀭𒁀𒌑) was a queen of Kish (c. 2500 BCE) — the only woman listed on the Sumerian King List as a sovereign monarch, and thus the first historically documented female ruler in human history. The Sumerian King List records her as a former tavern-keeper who founded a dynasty.
Rare but iconic in ancient Near Eastern studies.
Kubaba 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 Kubaba reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
