Robert II of France names his son Henry I as junior King of the Franks.

In 1027, King Robert II of France crowned his son Henry I as junior King of the Franks, securing the Capetian succession.
In 1027, reigning monarch Robert II of France elevated his eldest surviving son Henry as co-king, adopting the practice of associating heirs with the throne to ensure smooth succession. This ceremony took place at Reims, a traditional coronation site, reinforcing the legitimacy of the young prince within the Frankish realm. By crowning his heir during his own lifetime, Robert II followed a strategy to prevent succession disputes and rival claims. The event marked a key moment in the consolidation of Capetian rule, establishing a direct father-to-son lineage that would shape French monarchy. Henry I would later assume full powers upon his father's death in 1031, continuing the dynasty's steady hold over the kingdom. The coronation set a precedent for future French kings to secure dynastic continuity through early anointing of heirs.

The Siege of Nicaea begins during the First Crusade.

In 1097, Crusader forces commence the Siege of Nicaea, the first major target in Anatolia during the First Crusade.
In May 1097, a coalition of Western European forces under leaders such as Bohemond of Taranto and Godfrey of Bouillon laid siege to Nicaea, the Seljuk capital in Anatolia. The city’s formidable walls and strategic position on Lake Askanias made it a vital objective to secure a passage for Crusader armies toward Jerusalem. After weeks of blockade and skirmishes, Byzantine generals negotiated a secret surrender with the Seljuk defenders, handing the city to Emperor Alexios I Komnenos. The fall of Nicaea on June 19 boosted the Crusaders’ morale and underscored the complex alliance between Western knights and the Byzantine Empire. This victory opened the road to Iconium and laid the groundwork for subsequent battles at Dorylaeum and Antioch. The siege demonstrated the blend of military might and diplomatic maneuvering characteristic of the First Crusade.

During the 1465 Moroccan revolution which overthrows the Marinid dynasty, the Jewish mellah is attacked by the population of Fez, though the extent of the massacre is debated.

In 1465, during a revolt that ended Marinid rule in Morocco, the Jewish mellah of Fez suffered violence and looting amid popular unrest.
In May 1465, discontented citizens of Fez rose against the ineffective Marinid sultans, ending centuries of dynastic rule. Amid the chaos, the city’s Jewish quarter—the mellah—was targeted by mobs who looted homes and attacked inhabitants. Historical accounts vary on the scale of the violence, with estimates ranging from disorderly plunder to widespread massacre. The uprising installed Abd al-Haqq II’s vizier Abu Zakariya Yahya as ruler, inaugurating a period of political fragmentation. The events of 1465 had lasting impacts on Jewish-Muslim relations in Fez, shaping communal dynamics for generations. The revolt and its aftermath illustrate the volatility of late medieval North African politics and the vulnerabilities of minority communities.
