1447 may refer to the calendar year or to the integer 1447 itself. In Roman numerals, 1447 is written as MCDXLVII.

As a year, 1447 falls in the mid-15th century during the Late Middle Ages. In Western Europe, it occurred amid the ongoing Hundred Years’ War between England and France, a conflict shaping political and military developments of the period. In Ming China, the Zhengtong Emperor reigned and the Ming dynasty continued to administer the empire. The year sits within a broader medieval world marked by dynastic politics, religious life, and regional cultural flourishing, with ongoing interactions between different states and civilizations.

In mathematical terms, 1447 is a prime number. It is an odd integer and has no divisors other than 1 and itself. Its Roman numeral representation, as noted, is MCDXLVII, a form that reflects its composition from the standard subtractive and additive elements used in Roman numerals.
