Razia (رضية) is the Arabic word for "content" or "pleased." Sultana Razia (Raziyya al-Din, c. 1205-1240) was the only female sultan of Delhi — and one of the only female Muslim rulers in medieval India. She rode astride elephants in battle.
Razia is widely used in the Muslim world.
Razia 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 Razia reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
