Anti-king in the context of "Edward Balliol"

Conrad III (German: Konrad; Italian: Corrado; 1093 or 1094 – 15 February 1152) of the Hohenstaufen dynasty was from 1116 to 1120 Duke of Franconia, from 1127 to 1135 anti-king of his predecessor Lothair III, and from 1138 until his death in 1152 King of the Romans in the Holy Roman Empire. He was the son of Duke Frederick I of Swabia and Agnes, a daughter of Emperor Henry IV.

His reign saw the start of the conflicts between the Guelphs and Ghibellines. He was involved in the failed Second Crusade with Louis VII, where he would fight and lose at Doryleum and would later fall ill and return to Constantinople. After recuperating, he went to Jerusalem but would experience a string of failed sieges. Later returning from the Crusade, he was entangled in some conflicts with Welf VI's claim to the Duchy of Bavaria. On his deathbed, he designated his nephew Frederick Barbarossa as his successor instead of his son, Frederick IV, Duke of Swabia.

Stjepan Vukčić Kosača (1404–1466) was a powerful Bosnian nobleman who was politically active from 1435 to 1466; the last three decades of Bosnian medieval history. During this period, three kings acceded to the Bosnian throne: Tvrtko II, Thomas (Tomaš), Stephen Tomašević (Stjepan Tomašević) and anti-king Radivoj—the older brother of King Thomas—before the country was conquered by the Ottomans.

Stjepan, a son of the Knez of Drina, Vukac Hranić, and Katarina, whose ancestry is unknown, was probably born in 1404. Stjepan's father held hereditary lands in the Upper Drina region. Stjepan was a member of the Kosača noble family and became its chieftain in 1435 when he succeeded his uncle, Duke Sandalj, as Duke of Humska zemlja and the Grand Duke of Bosnia. Stjepan influenced the development of the late Bosnian medieval state more than any other person of his era.

William II (February 1227 – 28 January 1256) was the Count of Holland and Zeeland from 1234 until his death. He was elected anti-king of Germany in 1248 and ruled as sole king from 1254 onwards.

Henry VII (German: Heinrich; Vulgar Latin: Arrigo; 1275 or 1278/79 – 24 August 1313), also known as Henry of Luxembourg, King of Germany and King of Italy numbering is Heinrich VIII, was Count of Luxembourg, King of Germany (Rex Romanorum) from 1308 and Holy Roman Emperor from 1312. He was the first emperor of the House of Luxembourg. During his brief career he reinvigorated the imperial cause in Italy, which was racked with the partisan struggles between the divided Guelph and Ghibelline factions, and inspired the praise of Dino Compagni and Dante Alighieri. He was the first emperor since the death of Frederick II in 1250, ending the Great Interregnum of the Holy Roman Empire; however, his premature death threatened to undo his life's work. His son, John of Bohemia, failed to be elected as his successor, and there was briefly another anti-king, Frederick the Fair, contesting the rule of Louis IV.
