It depends what you mean by “algebra.” If you mean solving for unknowns, algebraic ideas go back several thousand years; if you mean algebra as a named, systematic subject or as symbolic/abstract algebra, those came much later.
Brief timeline and milestones
- c. 2000–1600 BCE (Babylon): Clay tablets show methods for solving linear and quadratic problems and systems of equations. The Babylonians used algorithmic procedures to compute unknowns.
- c. 1650 BCE (Egypt): The Rhind Mathematical Papyrus contains practical problems (some linear equations) solved by arithmetic methods.
- Classical Greece (c. 300 BCE): Mathematicians like Euclid expressed algebraic ideas geometrically (no symbolic notation).
- 3rd century CE: Diophantus of Alexandria wrote Arithmetica, an influential work using some symbols and methods for solving equations (he is often called the “father of algebra” in a Greek context).
- 7th century CE (India): Brahmagupta gave rules for arithmetic with zero and negative numbers and methods for quadratic equations.
- 9th century CE (Persia): Muhammad ibn Musa al-Khwarizmi wrote Al-Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala (c. 820). His systematic treatment of solving linear and quadratic equations gave the word “algebra” (al-jabr) to the subject.
- 11th–12th centuries: Islamic and Indian mathematicians (e.g., Omar Khayyam) worked on cubic equations and more advanced methods.
- 16th–17th centuries (Europe): François Viète introduced systematic symbolic notation; Descartes (La Géométrie, 1637) further developed modern symbolic algebra and connected it to geometry.
- 19th century onwards: Development of modern/abstract algebra (Galois, group theory, ring and field theory, and later formal axiomatic treatments by Dedekind, Noether, etc.).
Short answer
Algebraic thinking goes back at least 3–4 thousand years (Babylonians and Egyptians). The subject called “algebra” and treated systematically begins with al-Khwarizmi in the 9th century, while symbolic algebra and modern abstract algebra developed between the 16th and 19th centuries.
If you want, I can expand on any period (Babylonian methods, Diophantus, al-Khwarizmi’s book, or the development of symbolic/abstract algebra).
