Gongsun Shu (died 36) was a Chinese warlord who established the state of Chengjia in the Sichuan basin during the turbulent interregnum after Wang Mang’s fall. In 25 AD, he declared himself emperor, aiming to rival the Eastern Han dynasty and legitimize his rule. His administration focused on fortifying defenses, promoting agriculture, and organizing a centralized court. He maintained a strong cavalry and negotiated alliances with local tribes to secure his borders. Despite initial successes, his forces were gradually overwhelmed by Eastern Han campaigns. His defeat and death marked the end of Chengjia’s independence and reasserted Han control over western China.

Archbishop Sisinnius I held the patriarchal seat of Constantinople for a brief period from October 426 to December 427. He guided one of Christendom’s most important sees amid ongoing theological debates and ecclesiastical administration. Though his tenure was short, he is credited with convening synods to address clerical discipline and reinforce doctrinal clarity. Records of his early life and background are scarce, and much of his legacy survives in church annals. His death marked a transition to his successor, Nestorius, whose controversies would soon shake the Church. Sisinnius’s leadership helped maintain continuity in a pivotal era for Byzantine Christianity.

His compositions include masses, motets, and secular songs that were widely circulated in Europe. Dunstaple’s innovative use of harmony and texture laid the groundwork for future composers and helped shape the development of Western music. His legacy endures through surviving manuscripts that continue to be studied and performed by early music specialists.
