1229

1229 as a number

Viewed arithmetically, 1229 is an odd prime number and is written MCCXXIX in Roman numerals. It is sometimes used in indexing and cataloguing when the calendar year is treated numerically. Such simple numeric properties make the year a convenient label in chronicles, archival descriptions and mathematical lists of primes.

Major events

• Diplomacy in the Sixth Crusade: The crusading effort led by the Holy Roman Emperor concluded in 1229 by negotiation with Ayyubid rulers. The agreement restored Christian access and some control over parts of Jerusalem and other sacred sites for a period without the extensive fighting that marked many earlier crusades. The settlement was controversial among contemporaries and highlighted the role of diplomacy alongside military action in crusading policy.
• Conquest of Majorca: King James I of Aragon undertook a campaign that brought the Balearic island of Majorca under Christian rule. The conquest consolidated Catalan and Aragonese influence in the western Mediterranean, leading to resettlement and new maritime connections that affected trade and politics in the region.
• University of Paris unrest: The university experienced serious disturbances between students, masters and city authorities that interrupted teaching. The crisis led to a suspension of lectures by many masters and pupils and ultimately contributed to later papal measures to clarify university rights and privileges.

Importance and legacy

The events of 1229 illustrate several broader patterns of the 13th century: the increasing use of negotiated settlements in international affairs, the territorial expansion and colonization associated with Iberian polities, and the growing institutional autonomy of universities. The diplomatic recovery of parts of Jerusalem without major warfare was an unusual episode that generated debate among contemporaries. The conquest of Majorca influenced maritime power and colonization in the western Mediterranean, while disturbances at Paris were an important step in the long process that led to clearer legal status and protection for medieval universities.
