March 26

Born in 892, Li Zuo became Emperor Ai of Tang at the age of twelve, inheriting an empire weakened by internal strife and powerful eunuchs. His reign saw the declining influence of central authority as regional warlords gained autonomy. In 907, the military governor Zhu Wen forced his abdication, formally ending the Tang Dynasty. Ai was demoted to Prince of Jiyin and kept under house arrest until his death in 908. His brief and tumultuous reign symbolizes the fragmentation of imperial power in late medieval China. Though a minor figure in grand historical narratives, Emperor Ai's deposition marked a pivotal transition to the Five Dynasties and Ten Kingdoms period.

Little is known of Guntram's early life, but by the mid-10th century he had amassed extensive lands in the Upper Alsace region. His wealth and local influence earned him the epithet 'the Rich'. Operating during a period of weakened royal authority, he exercised quasi-sovereign powers over his territories. Scholars believe he may have been an ancestor of prominent houses that shaped Central European history. Despite the scarcity of contemporary records, archaeological findings attest to his patronage of monastic communities. His legacy survives in the dynastic ties that connected Frankish nobility across the Holy Roman Empire. Guntram's example illustrates the rise of regional magnates in post-Carolingian Europe.

Born in 936 into the Buyid dynasty, 'Adud al-Dawla became ruler of Fars and later de facto sovereign of the Abbasid Caliphate's western provinces.

He sponsored the construction of hospitals, bridges, and the celebrated Gundishapur Academy, turning Baghdad into a center of learning. A patron of the arts, he supported poets, scholars, and physicians, leaving an enduring cultural legacy. His fiscal policies stabilized the economy and strengthened central authority over recalcitrant governors.

Domestically, Sigurd strengthened royal authority by issuing the oldest surviving Norwegian royal charter. He rebuilt and founded churches, leaving a lasting ecclesiastical legacy. Upon his return, he secured peace with neighboring kingdoms and consolidated his rule. Sigurd's adventurous spirit and piety earned him enduring fame in Norse sagas. He died on March 26, 1130, closing a chapter of early medieval Norwegian engagement with Europe and the Holy Land.

Born in 1154, Sancho succeeded to the throne of Portugal in 1185. He earned the nickname "the Populator" for actively promoting settlement in frontier regions.

Her marriage strengthened ties between France and Luxembourg. She was crowned alongside her husband at Reims Cathedral. Marie died unexpectedly in 1324 at the age of 20. Her early death contributed to dynastic tensions that later influenced the French succession.

Born in 1312, Alfonso XI ascended to the Castilian throne as a minor under a regency council. He earned the epithet "the Avenger" after his decisive victory at the Battle of Río Salado in 1340 against Moorish forces. He implemented administrative reforms to centralize royal power and reduce noble influence. Alfonso was a patron of the arts and fostered architectural projects in Toledo and Seville. His reign was marked by both military success and the devastation of the Black Death. He succumbed to the plague in 1350, leaving a more unified Castile.

Born in 1378 as the eldest son of King Robert III of Scotland, David Stewart received the title Duke of Rothesay at a young age. He was appointed Lord High Admiral of Scotland and showed promise as a future ruler. His growing influence, however, led to friction with his uncle, the Duke of Albany. In 1402, David was arrested and held at Falkland Palace, where he died under mysterious circumstances. Rumors of foul play and political intrigue surrounded his death. His early demise had lasting repercussions for the Scottish succession.

Walter Stewart was born into the Scottish royal family and held the title Earl of Atholl. Initially a loyal subject, he became disillusioned with King James I’s policies. In 1437, he orchestrated the assassination of the king in Perth, a brazen act of regicide. Walter’s conspiracy plunged Scotland into political chaos and fear.

During his terms, Winthrop navigated relations with Indigenous peoples, other colonies, and the English crown. His leadership laid foundational principles for New England’s development and left a profound legacy in American history.
