1269

1269 may refer to multiple topics, including the year 1269 CE and the integer 1269.

As a year, 1269 CE falls in the middle of the 13th century, within the broader period of the High Middle Ages. The European political landscape continued to be shaped by feudal fragmentation and shifting power dynamics. In the Holy Roman Empire, the realm was in interregnum following the death of emperors, a situation that constrained centralized authority across many German-speaking lands. The aftermath of earlier conflicts in England left ongoing tensions between royal and baronial factions, influencing governance for years to come. Beyond Western Europe, the successor states of the Mongol Empire controlled wide territories and maintained complex diplomatic networks across Eurasia, affecting trade routes between Europe and Asia. In the Iberian Peninsula and the Levant, Christian and Muslim polities persisted in their long-running contests for territory, while urban centers continued to foster cultural and intellectual activity within the medieval world.

As a number, 1269 is an odd composite integer with prime factorization 3^3 × 47 (that is, 27 × 47). In Roman numerals it is MCCLXIX. In common base-10 representations, its binary form is 10011110101, its hexadecimal form is 0x4F5, and its octal form is 02365. The number is divisible by 3, 9, and 27, but not by 18, so it is not a Harshad number in base 10. It is not a triangular or square number. As a mathematical example, 1269 illustrates a composite with a small prime factor and a larger prime factor, highlighting basic factorization properties.
