Puduhepa (c. 1290-1220 BCE) was the great Hittite queen — wife of King Hattusili III — who co-ruled the Hittite Empire as Tawananna (Great Queen). She corresponded directly with Pharaoh Ramesses II as an equal, negotiating the marriage of her daughter to him. Her seal appears alongside her husband's on the Treaty of Kadesh — the world's earliest surviving international peace treaty (1259 BCE).
Her diplomatic letters are preserved in the Hittite archives at Hattusa.
Puduhepa 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 Puduhepa reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
