Drusus Julius Caesar (7 BC – AD 23) was the only biological son of Emperor Tiberius and Vipsania Agrippina. Adopted by Tiberius as his heir, he held positions such as consul and retained the prestige of the Julio-Claudian house. Renowned for his reserved and dignified character, he was seen as a stabilizing presence amid court intrigue. He was implicated in a conspiracy and died under suspicious circumstances, widely believed to be the result of poisoning orchestrated by Sejanus. His untimely death altered the course of imperial succession, leading to increased instability in the Roman Empire.

Thascius Caecilius Cyprianus (c. 200–258) served as Bishop of Carthage during a time of intense persecution of Christians under Emperor Valerian. A convert to Christianity in his adulthood, he became famous for his eloquent letters and treatises on church unity and discipline. Cyprian clashed with schismatic clergy and emphasized the importance of a unified church under episcopal authority. During the Valerian persecution, he was arrested and executed in Carthage, becoming one of the most venerated martyrs of the early church. His works greatly influenced Western Christianity and his feast day is celebrated in both Eastern and Western traditions.

John Chrysostom (347–407) rose from a hermit life near Antioch to become Archbishop of Constantinople and one of the most influential early Christian preachers. Nicknamed 'Chrysostom' or 'golden-mouthed' for his eloquent orations, he reformed clergy discipline and challenged abuses of wealth and power. His liturgical contributions include the Divine Liturgy of St John Chrysostom, still central to Eastern Orthodox worship. Political conflicts with Empress Eudoxia led to his exile, during which he continued writing letters and homilies. He died in exile on the Black Sea coast and was later declared a saint by both Eastern and Western churches.

Emperor Bidatsu (538–585) was the 30th sovereign according to the traditional order of Japanese emperors and reigned from 572 until his death. His rule coincided with the growing influence of Buddhism, leading to debates between pro- and anti-Buddhist clans. He supported the Soga clan's promotion of Buddhism, which caused tensions with conservative factions. Little is recorded about his personal achievements, but his reign set the stage for subsequent Asuka period reforms. He died at a young age, and his policies influenced the evolution of imperial authority and state religion in Japan.

Yang You (605–619), known as Emperor Gong of Sui, was placed on the throne in 617 by the rebel general Yuwen Huaji. A grandson of Emperor Wen, he had no real power and served as a figurehead during the dynasty's decline. The Sui Dynasty faced widespread rebellions, heavy taxation, and military failures that weakened imperial control. After the assassination of Emperor Yang, he was briefly recognized before being deposed by the rising Tang forces. His death marked the end of Sui rule and paved the way for the establishment of the Tang Dynasty.

Constantine V (718–775) became Byzantine co-emperor as a child and ruled alone from 741 until his death. He successfully defended the empire against Arab and Bulgar invasions, securing key eastern territories. A staunch iconoclast, he implemented policies that destroyed religious images and persecuted their supporters. He reformed the army and civil administration, strengthening central authority and fiscal stability. His controversial reign had a lasting impact on Byzantine religious and political life.

Al-Hadi (764–786) succeeded his father al-Mahdi as the fourth caliph of the Abbasid dynasty in 785. Eager to reduce the influence of his mother, Al-Khayzuran, he attempted to centralize power in his own hands. His short reign was marked by tensions with the elite and military factions within the capital. In 786, he died suddenly under mysterious circumstances, leading to speculation of palace intrigue. Although his rule was brief, his struggles highlighted challenges of governance in the early Abbasid Caliphate.

Li Mian (717–788) served the Tang court in multiple roles including judge, military general, and regional governor. He earned a reputation for strict fairness in legal affairs and loyalty to the imperial family. On the battlefield, he defended frontier territories against rebels and external threats. A cultured scholar, he composed poems and music reflecting the refined tastes of the Tang elite. His multifaceted career exemplified the scholar-official ideal of medieval China.

Li Yong served as a high-ranking chancellor in the late Tang court, overseeing civil administration and advising the emperor. He was respected for his sound judgment and efforts to maintain stability amid political strife. Though few details survive about his policies, he is remembered for his dedication to good governance. He died in 820, concluding a notable career in imperial service. His example influenced later generations of Tang officials.

Stephen V (d. 891) served as pope from 885 until his death, guiding the Church through political and social upheavals. He solidified ties with the Frankish rulers to protect Rome and church interests. Stephen granted privileges to missionaries such as Cyril and Methodius, aiding the conversion of Slavic peoples. He also addressed internal church disputes and sought to reinforce clerical discipline. His pontificate left a legacy of stronger papal influence in both religious and secular affairs.

Niall Glúndub reigned as High King of Ireland from 916 to 919. He belonged to the Ui Neill dynasty and worked to assert Gaelic power across Ireland. He led successful military campaigns against Norse settlements, notably defending Ulster. His strategic alliances with regional kings strengthened his authority. He fell in battle near Dublin while confronting Viking forces. His reign is celebrated as a pivotal period in early medieval Irish resistance to Norse expansion.

Cele Dabhaill mac Scannal was a prominent Irish abbot who led a major monastic community in the early 900s. He oversaw religious practices, education, and manuscript copying within his abbey.
