   Al-Khwarizmi was reportedly born in Khwarazm, the Central Asian oasis region from which his nisba derives. This origin is disputed: another interpretation associates him with Qutrubbul near Baghdad. The date is approximate. Coordinates represent the broad historic Khwarazm region; the specific birthplace is unknown, and scholarly interpretations of his origin differ.

2. Works at the House of Wisdom

   Around 820, al-Khwarizmi worked at Baghdad’s House of Wisdom, the Abbasid scholarly and library milieu associated with Caliph al-Ma'mun. This is the clearest dated evidence for his professional presence in Baghdad. The date is approximate. The medieval House of Wisdom’s exact site is not securely identified, so the coordinates represent Baghdad.

3. Writes his algebra in Baghdad

   Around 825, al-Khwarizmi composed his foundational work on al-jabr and al-muqabala in Baghdad. The treatise systematized methods for solving linear and quadratic equations and became the work from whose title the word “algebra” derives. The date is approximate, and the source identifies Baghdad rather than a specific writing site.
