Alfonso XI, called the Avenger, was King of Castile and León. He was the son of Ferdinand IV of Castile and his wife Constance of Portugal. Upon his father's death in 1312, several disputes ensued over who would hold regency, which were resolved in 1313.
John IV, nicknamed John the Restorer, was the King of Portugal whose reign, lasting from 1640 until his death, began the Portuguese restoration of independence from Habsburg Spanish rule. His accession established the House of Braganza on the Portuguese throne, and marked the end of the 60-year-old Iberian Union by which Portugal and Spain shared the same monarch.

Sancho IV of Castile called the Brave, was the king of Castile, León and Galicia from 1284 to his death. Following his brother Ferdinand's death, he gained the support of nobles that declared him king instead of Ferdinand's son Alfonso.

Edmund of Langley, Duke of York was the fourth surviving son of King Edward III of England and Philippa of Hainault. Like many medieval English princes, Edmund gained his nickname from his birthplace: Kings Langley Palace in Hertfordshire. He was the founder of the House of York, but it was through the marriage of his younger son, Richard of Conisburgh, 3rd Earl of Cambridge, to Anne de Mortimer, great-granddaughter of Edmund's elder brother Lionel of Antwerp, 1st Duke of Clarence, that the House of York made its claim to the English throne in the Wars of the Roses. The other party in the Wars of the Roses, the incumbent House of Lancaster, was formed from descendants of Edmund's elder brother John of Gaunt, 1st Duke of Lancaster, Edward III's third son.
The Kingdom of León was an independent kingdom situated in the northwest region of the Iberian Peninsula. It was founded in 910 when the Christian princes of Asturias along the northern coast of the peninsula shifted their capital from Oviedo to the city of León. The kings of León fought civil wars, wars against neighbouring kingdoms, and campaigns to repel invasions by both the Moors and the Vikings, all in order to protect their kingdom's changing fortunes.
Joanna of Castile, known as la Beltraneja, was a claimant to the throne of Castile, and Queen of Portugal as the wife of King Afonso V, her uncle.
Maria of Portugal was a Portuguese princess who became Queen of Castile upon her marriage to Alfonso XI in 1328. She was the eldest daughter of King Afonso IV of Portugal and his wife Beatrice of Castile.
Henry IV of Castile, nicknamed the Impotent, was King of Castile and León and the last of the weak late-medieval kings of Castile and León. During Henry's reign, the nobles became more powerful and the nation became less centralised.
The Iberian Union was the dynastic union of Spain and Portugal that existed between 1580 and 1640 and brought the entire Iberian Peninsula, as well as Portuguese and Spanish overseas possessions, under the Spanish Habsburg monarchs Philip II, Philip III, and Philip IV. The union began after the Portuguese crisis of succession and the ensuing War of the Portuguese Succession, and lasted until the Portuguese Restoration War, during which the House of Braganza was established as Portugal's new ruling dynasty with the acclamation of John IV as the new King of Portugal. This was a personal union, so the Kingdoms of Portugal and Spain remained independent states, sharing only a single monarch.
The Philippine dynasty, also known as the House of Habsburg in Portugal, was the third royal house of Portugal. It was named after the three Habsburg Spanish kings, all named Philip, who ruled Portugal between 1581 and 1640 under the Iberian Union, a dynastic union of the crowns of Spain and Portugal. The dynasty's kings were Philip I, Philip II and Philip III.

Joana, Princess of Beira was a Portuguese infanta (princess), and the eldest surviving daughter of John IV, King of Portugal and his wife Luisa de Guzmán.

The Kongo Civil War (1665–1709) was a war of succession between rival houses of the Kingdom of Kongo. The war waged throughout the middle of the 17th and 18th centuries pitting partisans of the House of Kinlaza against the House of Kimpanzu. Numerous other factions entered the fray claiming descent from one or both of the main parties such as the Água Rosada of Kibangu and the da Silva of Soyo. By the end of the war, Kongo's vaunted capital had been destroyed and many Bakongo were sold into the Trans-Atlantic Slave Trade.
The Battle of Mbidizi River was a military engagement in June 1670 between forces of the County of Soyo and those of the Portuguese colony of Angola during the Kongo Civil War. The engagement was part of a military campaign to break the power of Soyo in the region. The Portuguese won a decisive victory, inflicting heavy casualties and killing the Soyon leader.
