1435

1435 can refer to either the year 1435 CE in the Julian calendar or to the integer 1435 itself. As a year in late medieval Europe, it falls within a period of ongoing dynastic conflicts, evolving national polities, and shifting alliances that shaped the course of the Hundred Years’ War and related power struggles.

In the historical record, 1435 is notable for the signing of the Treaty of Arras between the Kingdom of France and the Duchy of Burgundy. The treaty helped end the Armagnac–Burgundian civil conflict within France and realigned Burgundian and French interests against England, contributing to a realignment of alliances during the later stages of the Hundred Years’ War. The broader political landscape of the era was marked by attempts at reconciliation, consolidation of royal authority, and continued warfare across various regions of Europe.

As a mathematical object, 1435 is the product of three prime numbers: 5, 7, and 41 (1435 = 5 × 7 × 41). It is an odd composite number. In Roman numerals, 1435 is written as MCDXXXV. The number has a digit sum of 13 and does not form a palindrome.

In calendar terms, 1435 was a regular year in the Julian calendar, without leap days that year. The year sits within the broader medieval synthesis of political, religious, and cultural developments that characterized the mid-15th century.
