Boril (Bulgarian: Борил) was the emperor (tsar) of Bulgaria from 1207 to 1218. He was the son of an unnamed sister of his predecessor, Kaloyan and Kaloyan's brothers, Peter II and Ivan Asen I, who had restored the independent Bulgarian state. After Kaloyan died unexpectedly in October 1207, Boril married his widow, a Cuman princess and seized the throne. His cousin, Ivan Asen, fled from Bulgaria, enabling Boril to strengthen his position. His other kinsmen, Strez and Alexius Slav, refused to acknowledge him as the lawful monarch. Strez took possession of the land between the Struma and Vardar rivers with the support of Stefan Nemanjić of Serbia. Alexius Slav secured his rule in the Rhodope Mountains with the assistance of Henry, the Latin Emperor of Constantinople.
Boril launched unsuccessful military campaigns against the Latin Empire and the Kingdom of Thessalonica during the first years of his reign. He convoked the synod of the Bulgarian Church in early 1211. At the assembly, the bishops condemned the Bogomils for heresy. After an uprising broke out against him in Vidin between 1211 and 1214, he sought the assistance of Andrew II of Hungary, who sent reinforcements to suppress the rebellion. He made peace with the Latin Empire in late 1213 or early 1214. After Henry died in 1216 and Andrew II left Hungary for a crusade, Ivan Asen returned to Bulgaria. He captured and blinded Boril in Tarnovo in 1218.
Alexius Slav (Bulgarian: Алексий Слав, Greek: Ἀλέξιος Σθλαῦος; fl. 1208–28) was a Bulgarian nobleman (bolyarin), a member of the Asen dynasty, and a nephew of the first three Asen brothers. He was first probably the governor of the Rhodopes domain of the Second Bulgarian Empire, and then an autocrat in these lands.
He was first mentioned as one of the nobles disputing Tsar Boril's ascension to the Bulgarian throne. He married the daughter of Latin Emperor Henry of Flanders in November 1208, leaving the Bulgarian capital of Veliko Tarnovo and establishing himself as an independent ruler over the largest part of the Rhodope Mountains. Alexius Slav became a vassal of Henry after the Bulgarian defeat near Plovdiv. Henry promised to support his aspirations for the Bulgarian throne and awarded Alexius Slav the title of despot.
Pelagio Galvani (c. 1165 – 30 January 1230, Portuguese: Paio Galvão Latin: Pelagius) was a Leonese cardinal, and canon lawyer. He became a papal legate and leader of the Fifth Crusade.
Born at Guimarães, his early life is little known. It is repeatedly claimed that he entered the Order of Saint Benedict but this is not proven. Pope Innocent III created him cardinal-deacon of Santa Lucia in Septisolio around 1206. Later, he was promoted to the rank of cardinal-priest of S. Cecilia (probably on 2 April 1211), and finally opted for the suburbicarian see of Albano in the spring of 1213. He subscribed the papal bulls between 4 May 1207 and 26 January 1230. He was sent on a diplomatic mission to Constantinople in 1213. During this two-year mission he attempted to close Orthodox churches and imprison the clergy, but this caused such domestic upset that Henry of Flanders, the Latin Emperor of Constantinople, reversed his actions which had caused the "tempest which held the city of Constantine in its grip", as noted a contemporary historian. Three years later he was elected Latin Patriarch of Antioch but his election was not ratified by the Holy See. He was dispatched in 1218 by Pope Honorius III to lead the Fifth Crusade at Damietta in Egypt, and made a poor strategic decision in turning down favourable peace offers made by the sultan al-Kamil. During his absence, the see of Albano was administer by Thomas of Capua.
