João de Castro was born into Portuguese nobility in 1500 and pursued a military career that took him to the Indian Ocean. Appointed as the fourth Governor of Portuguese India, he reformed fortifications and improved colonial administration. An accomplished cartographer and scholar, he documented ocean currents and navigational techniques in his famed travel journals. His explorations contributed significantly to European understanding of the East African coast and Indian maritime routes. Castro’s blend of military leadership, scholarly inquiry, and statesmanship made him a pivotal figure in the Age of Discovery before his death in Goa in 1548.

Born in 1556, Nakagawa Kiyohide became a prominent daimyo under Oda Nobunaga. He was known for his military skill and governed key territories in Yamato Province. His forces clashed with Toyotomi Hideyoshi at the Battle of Shizugatake. He died in the melee of that conflict, marking the end of his clan's rise. His legacy remains in historical accounts of the Sengoku period.

Born in 1837 in Ohio, Quantrill grew up in Kansas during border conflicts. He formed a band of irregular fighters known as Quantrill's Raiders in 1861. His men carried out brutal raids, most infamously the 1863 Sack of Lawrence, Kansas. Quantrill employed guerrilla tactics that terrorized civilian populations. He was wounded in 1865 and died shortly after from his injuries. William Quantrill remains a controversial figure in Civil War history.

Yuan Shikai was a prominent military leader who played a key role in the late Qing dynasty's modernization of the army. He negotiated the abdication of the last emperor in 1912 and became the first Provisional President of the Republic of China. In 1913 he was elected the second President, consolidating power and centralizing the government. His presidency was marked by efforts to stabilize the country but also by accusations of autocracy. In 1915 he proclaimed himself emperor, a move that sparked widespread opposition and rebellion. Facing mounting resistance, he abandoned the monarchy but remained a controversial figure until his death in 1916.

Byng earned fame for commanding the Canadian Corps at the Battle of Vimy Ridge in 1917, a victory that became a symbol of national pride for Canada. His decisive tactics and refusal to bow to political pressure earned him respect among military and civilian circles. Promoted to field marshal in 1919, he held several high command positions before his appointment as Governor-General of Canada in 1921. In that role, he navigated constitutional challenges and promoted cultural and agricultural development. His tenure saw the so-called 'King–Byng Affair', a constitutional crisis that affirmed the limits of vice-regal power. After returning to Britain, he continued to influence military affairs until his death in 1935.
