Duke of Milan in the context of "Ludovico Sforza"

Philip II (21 May 1527 – 13 September 1598), sometimes known in Spain as Philip the Prudent (Spanish: Felipe el Prudente), was King of Spain from 1556, King of Portugal from 1580, and King of Naples and Sicily from 1554 until his death in 1598. He was also jure uxoris King of England and Ireland from his marriage to Queen Mary I in 1554 until her death in 1558. Further, he was Duke of Milan from 1540. From 1555, he was Lord of the Seventeen Provinces of the Netherlands.

The son of Emperor Charles V and Isabella of Portugal, Philip inherited his father's Spanish Empire in 1556, and succeeded to the Portuguese throne in 1580 following a dynastic crisis, forming the Iberian Union. The Spanish conquests of the Inca Empire and of the Philippines, named in his honour by Ruy López de Villalobos, were completed during his reign. He finished building the royal palace El Escorial in 1584. Under Philip II, Spain reached the height of its influence and power, advancing into the Spanish Golden Age, and ruled territories in every continent then known to Europeans. Deeply devout, Philip saw himself as the defender of Catholic Europe against the Ottoman Empire and the Protestant Reformation, and invested Spain's position as the leading European power in multiple simultaneous warring efforts.

Bona of Savoy (10 August 1449 – 23 November 1503) was Duchess of Milan as the second wife of Galeazzo Maria Sforza (1444–1476), Duke of Milan. Following her husband's assassination in 1476, she served as regent of Milan for her son, Gian Galeazzo Sforza, during his minority from 1476 to 1481.

As regent, Bona played a significant political role in attempting to preserve the stability of the Sforza rule amidst internal power struggles. She was also the original patron of the lavishly illuminated Sforza Book of Hours, one of the finest surviving Renaissance books of hours.

Gian Galeazzo Sforza (20 June 1469 – 21 October 1494), also known as Giovan Galeazzo Sforza, was the sixth Duke of Milan. He was the father of Bona Maria Sforza, who later became Queen of Poland. He died in 1494 aged 25 and was succeeded by his uncle, Ludovico Sforza.

Francesco II Sforza (4 February 1495 – 1 November 1535) was Duke of Milan from 1521 until his death. He became duke of Milan after Emperor Charles V reconquered it from the French. He fought at the Battle of Bicocca against the French, but in 1526 joined the League of Cognac with Francis I of France. Surviving a poisoning, he married Christina of Denmark, but died childless. He was the last member of the Sforza family to rule Milan.

Francesco I Sforza KG (Italian: [franˈtʃesko ˈpriːmo ˈsfɔrtsa]; 23 July 1401 – 8 March 1466) was an Italian condottiero who founded the Sforza dynasty in the duchy of Milan, ruling as its (fourth) duke from 1450 until his death. Renowned for his military skill and political acumen, he was among the few condottieri to successfully transform battlefield success into stable dynastic rule.

In the 1420s, he took part in the War of L'Aquila, and during the 1430s he served both the Papal States and the Duchy of Milan in their conflicts against Venice. Following the Peace of Cremona (1441), which he helped broker, Sforza married Bianca Maria Visconti, daughter of Duke Filippo Maria Visconti, thus strengthening his claim to Milan. After a brief military campaign in southern Italy with René of Anjou, he returned to Milan and seized control following the extinction of the Visconti line.

Cecilia Gallerani (Italian pronunciation: [tʃeˈtʃiːlja ɡalleˈraːni]; early 1473 – 1536) was the favourite and most celebrated of the many mistresses of Ludovico Sforza, known as Lodovico Il Moro, Duke of Milan. She is best known as the subject of Leonardo da Vinci's painting Lady with an Ermine (c. 1489). While posing for the painting, she invited Leonardo, who at the time was working as court artist for Sforza, to meetings at which Milanese intellectuals discussed philosophy and other subjects. Gallerani herself presided over these discussions.

Lucrezia Crivelli (1464-1534), was an Italian noblewoman and lady-in-waiting. She was a mistress of Ludovico Sforza "il Moro", Duke of Milan. She was the mother of Sforza's son, Giovanni Paolo I Sforza, Marquess of Caravaggio. Crivelli has been thought to be the subject of Leonardo da Vinci's painting, La belle ferronnière.
