Casimir I the Restorer (1016–1058) was Duke of Poland who reunited and stabilized the Polish realm after a period of feudal division. Ascending to power in 1039, he recovered territories lost to Bohemia and Kievan Rus' and reasserted central authority. He reformed the administration by restoring the voivode system, strengthening royal taxation, and promoting the Church's role in governance. His marriage to Maria Dobroniega of Kiev secured vital alliances and dynastic ties. Casimir's efforts laid the groundwork for the flourishing Piast dynasty and the long-term survival of the Polish state.

Afonso I (1109–1185), also known as Afonso Henriques, was the first King of Portugal and architect of a new nation. He declared Portugal's independence from the Kingdom of León after his victory at the Battle of Ourique in 1139. Throughout his reign, he expanded his domain southward during the Reconquista, capturing key cities such as Santarém and Lisbon. In 1179, Pope Alexander III issued the Papal Bull Manifestis Probatum, formally recognizing his royal title and Portugal's sovereignty.

Arthur II (1261–1312) was Duke of Brittany who consolidated ducal power and navigated the duchy's position between France and England. Succeeding his father John II in 1305, he faced internal noble rivalries but secured his rule through strategic alliances and military action. Arthur granted charters to towns, promoting commerce and urban development throughout Brittany. He maintained diplomatic ties with both French and English crowns, preserving Brittany's semi-autonomous status. His patronage of legal reforms and cultural projects left an enduring mark on Breton identity and governance.

Hawys Gadarn (1291–1353), known as the Hardy, was a medieval Welsh noblewoman who became legendary for defending her rights to the Lordship of Powys. After her brother's death, her uncle attempted to seize the family estates, prompting Hawys to petition King Edward III. The king convened a council that ruled in her favor, restoring her inheritance and establishing a precedent for inheritance rights. Hawys went on to manage her estates effectively, gaining respect from her tenants and the crown. Her story remains a celebrated example of medieval noble authority and legal recourse.

His reign, however, was cut short when he was assassinated by discontented nobles in 1437.

Philip I (1404–1430) was Duke of Brabant who oversaw a period of economic growth and civic development in his duchy. He encouraged trade by supporting merchant guilds and granting town charters that increased urban privileges. Philip secured peace with neighboring territories through strategic marriages and treaties, protecting Brabant's strategic interests. He also fostered artistic and cultural patronage, attracting painters and artisans to his court. Although his early death in 1430 led to a brief succession crisis, his policies had already set the stage for Brabant's sustained prosperity.

Henry Percy (1421–1461), the 3rd Earl of Northumberland, was a powerful English noble and key figure in the Wars of the Roses. A staunch Lancastrian, he fought at the Battles of St Albans and Wakefield and advised King Henry VI.

Born in 1750 in Boston to modest parents, Henry Knox rose from bookseller to become the Continental Army’s chief artillery officer. His daring transport of captured British cannons from Fort Ticonderoga during the harsh winter of 1775–76 was a turning point in the Siege of Boston.
