The quote goes as follows: "I am born of a rank that recognizes no superior but God."
Welcome to No Superior But God ATL. The name is derived from a quote from Richard I, King of England, made to his captor and ransomer, Henry VI, Holy Roman Emperor that he gave in defiance of the Emperor's request for Richard to show deference to him.
In 1193, Henry VI captured Richard the Lionheart on his return trip to England from his crusades in the Holy Land. Eager to help fund an army for his designs on Sicily, Henry VI ransomed King Richard for an exorbitant sum. Pope Celestine III had long opposed Henry VI and his attempts to unite southern Italy with Holy Roman realm. Seeing as imprisoning crusaders was fundamentally illegal in the eyes of the Church, Celestine III naturally excommunicated Emperor Henry. Richard's ransom was paid, and Emperor Henry VI did not see the excommunication as all-together extremely detrimental to his campaign on Sicily. However, upon reaching Sicily and finding the nobles of Palermo and the island openly rebelling against his authority due to in part his excommunication, Henry VI took a bold, aggressive action that would have far-reaching consequences. He took his army and marched on Rome itself. Easily securing his march through Italy, he reached Rome and forced Pope Celestine III to relinquish his power, demanding an immediate gathering of the Cardinals to elect a new Pope. With the Papal States occupied by the German king's forces, the Roman Curia was forced to elect a weak-willed, pro-German Pope named Marinus III. Pope Celestine III stepped down as Pope and was exiled to the Kingdom of Castile as per Emperor Henry VI's orders. Henry VI now had full Papal backing, and the stability of Sicily was more secure. Henry VI then forced the newly elected Marinus III to issue a Papal Bull that described the exact relationship of the Emperor and the Pope. This was to be called posthumously the Roman Seal of 1193. This included the following:
- The German Prince-Electors have the right to elect the King of the Romans, free of influence of the Pope.
- The King of the Romans, as official protector of the Pope, has a necessary power to anoint and consecrate an election of the Pope and legitimate Papal authority.
- The King of the Romans reserves the right to demand the Papal Curia elect a different Pope if the Emperor deems an elected Pope unfit for the the theological authority of the position. This power comes from the Holy Roman Emperor's responsibility as defender of the faith, and therefore defender of Christianity from Popes that are unfit to lead the faith, and may lead all of Christendom into a possibly heretical or factionalist future, dominated by corruption and dynastic nepotism within the Papal hierarchy.
- 1194, Alfonso VIII of Castile lost the Battle of Alarcos, as in the OTL, however, Alfonso IX of Leon launched a successful invasion of Castile after the disaster of Alarcos in an attempt to take back lands lost to Castile years prior, also as in the OTL. Without an effective Pope to excommunicate Alfonso of Leon, the Christian powers of Iberia did not unite against Alfonso of Leon in support of Castile. Instead, a temporary yet effective alliance between Leon and the Almohad Caliph al-Mansur formed, leading to major setbacks in the Christian reconquest, including the loss of Toledo, then the capital of Castile, to the Almohad Caliphs. The Almohads subsequently took greater interest in their Iberian holdings, with the major setback of the Reconquista set as the impetus for a major push against the now disjointed and bickering Christian powers.
- 1195, The Kingdom of Leon, having successfully curbed the rising power of the Castilian Kingdom, now in turn made peace with Castile, marries Berengaria of Castile, as in the OTL. The couple, however, does not have their marriage annulled by the Papacy as in the OTL. They give birth to a son, the future Ferdinand III of Leon, who will inherit a Leonese realm and a truncated Castilian Kingdom.
- The Teutonic Knights is never confirmed to be a legitimate military order by the weak-willed Pope.
- 1196, Both the Imperial Diets of Wurzburg and Erfurt made the imperial crown hereditary, and specifically belonging to Henry VI's house of Hohenstaufen, delegating his successor as his son, Frederick II, or in the case of Henry's untimely death prior to his son coming of age, the crown would go to Philip, Duke of Swabia. Though this was approved my a majority of the Prince-Electors, a noticeable minority headed by powers such as Otto of Brunswick and Ottokar I of Bohemia did not agree with the formation of a hereditary crown for the King of the Romans at either Diets.
- 1197, Henry VI, attempting to further pacify his Sicilian domain, stays in Palermo and southern Italy until September of 1198, where he is poisoned while preparing for a crusade.
- 1199, Philip of Swabia, brother of Henry VI, claims rights as King of the Romans through the the agreements at the Diets of Wurzburg and Erfurt. Otto of Brunswick, a notable leader of the minority vote of Prince-Electors against hereditary crown at both Diets, openly refused to acknowledge the legitimacy of Philip's status as Emperor. He was elected by the Prince-Electors in northern Germany, notably the Duchy of Bohemia, against Philip who had the backing of the Papal authority and the southern Prince-Electors.
- 1199, Richard I of England, after enduring hardship and being ransomed by the Staufen dynasty, supports Otto of Brunswick against Philip of Swabia. To challenge this, Philip II Augustus of France sides with Philip of Swabia, against English ambitions.

- 1202, Alfonso of Leon leads a coalition of Christian Kingdoms, including the King of Portugual, Sancho of Navarre, and Alfonso of Castile, against the newly revitalized Almohad Caliphate. The coalition set out to siege Toledo, the capital of Castile that had been retaken by the Almohads in their joint-Leonese war against Castile. Only the armies of Aragon were not present. The Caliph al-Mansur, beginning to invest greater interest and troops to his Andalusian holdings in Iberia, raised a force of 150,000 troops from across the Maghreb and Iberian Almohad holdings. He also recruited many local Christian mercenaries in the nearby regions of Toledo. The siege was a failure, resulting in the death of Alfonso of Castile. al-Mansur did not capitalize on this victory by in turn invading the Christian kingdoms, and instead set about pacifying Toledo and the surround cities which had not long ago been under Castilian dominion.

- 1206, Philip of Swabia, Holy Roman Emperor, granted Ottokar I of Bohemia his rights as a King of Bohemia, making his realm void of Emperor appointment and made Ottokar's dynasty the hereditary and permanent rules of Bohemia.

- September 28, 1208, Philip of Swabia accepts the surrender of Otto of Brunswick, executing him thereafter.

- 1295, The Pope calls the Crusade of Lisbon, a crusade directed against Portugal, which had in frequent decades allied with the Seville Almohads and disrupted the southward push of the Christian states by attacking them when they were besieging the moors.

The Almohads remain neutral and defend their borders.

February 9, 1297, After years of a struggle between the Holy Roman Empire and the Papal authority, involving many excommunications and invasions of the Holy See, the last Pope to have rejected completely the Roman Seal of 1193 dies and a Papal Curia is called to elect a new Pope. The Curia, for the first time since the Roman Seal of 1193, calls the Holy Roman Emperor, Conradin, to sanction their election of the new Pope. Tensions between the Papacy and the Holy Roman Empire decrease, and the King of the Romans for the first time officially anoints the Pope. The Pope, taking the title Celestine VI, officially recognizes the Roman Seal of 1193, the first Pope to do so since the Pope Marinus III who was elected under the pressure of the King of the Romans' army.
