IV - The King and the Knights
The nobles hoped that the era of authoritarian, indomitable monarchs ended with Margaret's death. However Philippa, hailing from the intrigue-filled Plantagenet court herself, did her best to prepare her only son to stand up for the task at hand.
Contemporary descriptions depict Christian as a "handsome and elegant man", of "hot temper and great arrogance". He was also said to be fluent in five languages at the time of his ascencion - Danish, Swedish, Norwegian, Latin and French - as well as capable of conversing with Polish king Alexander and Teutonic grand master Ludwig Anton von Pflaz, which implies at least moderate knowledge of Polish and German. A great talent for languages, he apparently lacked in other court duties, as very few administration acts bear his signature.
Soon after his coronation, the king embarked on a grand voyage, visiting first his Gryfite cousins at Darłowo, then moving on to Lübeck, London and Dunfermline. It was there, on court of James I Stuart, where he married his first wife Isabella, second daughter of the Scottish king
*. Alliance with the Scottish was a part of a greater scheme, partly made on Philippa's behalf; after sudden and unexpected death of Henry IV and his son and successor Henry V during an outbreak of plague, the crown of England fell upon a newborn Ceasar; marriage with the Stuarts was to secure at least one stable ally on the other side of the Northern Sea, should the Plantagenets lose crown.
Upon his return in March 1416, Chrisitan had to face an unexpected challenge to his authority; Oluf Bille, son of Maximilian, rallied a large faction of nobles, hoping to avenge his father's exile and uncle death. Using Maximilian's many estates as power and financial base, he almost managed to mount a sizeable army and would have surely seized Copenhagen, should Christian not return on time to save the day. Preceded by a rumor of Scottish regiments coming onboard the returning fleet, the rightful monarch offered to pardon all who kneel - with the exception being the whole Bille family. Fearing for their precious holding, the nobles disarmed peacefully, and Oluf joined his late father in exile in Scotland. Upon his death in 1423, his estates have been forcibly incorporated into crown domain - despite his last will donating them to the Church.
His throne secured, Christian was finally ready to face the real foe - the still powerful Teutonic Order. Following Konrad von Jungingen's death in 1407, the Order's chapter elected young and energetic Ludwin Anton for the grand master. Using the wealth of Prussian cities to rebuild the shattered fleet, he also actively sought allies abroad - which allowed him to discard the Peace of Elbing in 1417, forcing Kalmar merchants out of Danzig and seizing Danish and Swedish ships present in Danzig at the moment.
This obvious
casus belli was not utilised by Christian only because Ludwig Anton had found a powerful protector; Polish king Alexander considered expanding Danish influence to be a greater threat to the young Polish-Lithuanian Commonwealth than the (seemingly) weak Order - and promised to intervene on Teutons' behalf should Christian and his armies appear in Prussia. The spectre of war was dispelled - but destroying the Order and avenging this slight became Christian's lifelong obsession, as expressed in his letter to margrave of Brandenburg (and his cousin) August I: "Ordo delenda est".
Encouraged by Jagiellonian support, Ludwig Anton started an aggressive campaign, aimed against Kalmar merchants in the Baltic basin. Its culmination was the invasion of Lübeck in 1426, when the Teutonic fleet entered the port, deploying a small detachment that burnt many magazines, mostly belonging to Kalmar and English merchants. Infuriated, Christian ordered the fleet to sail out and engage the Teutons - but an unexpected storm forced the galleys back to Copenhagen. Realising the incoming threat, Ludwig Anton returned to Königsberg, leaving devastated Lübeck in his wake.
Realising sabre-rattling alone wouldn't break the cunning grandmaster, Christian switched to a more subtle approach, using his cousing August of Brandenburg to establish contacts with Alexander Jagiellon. Difficult negotiations produced a visible result in 1430, when during a meeting in Płock Danish princess Anna became wife to August, successor to the throne of Poland. Although this act alone did not end Polish guarantees to the Order, it broke the ice, making first contact between the two powers - and being the first step in alienating the Order.
Meanwhile, in Livonia, the once-powerful Livonian Order was entering the greatest crisis of its history; facing a revolt of civilian population (which in significant portion consisted of Orthodox) and a complete collapse of state administration, it slowly degenerated into merely a scene for two most important Baltic players of that time - Ludwig Anton and Christian. As the king and the knight moved in to scavenge the crumbling state, king Alexander in Kraków pondered on his options. Although far from sea, Wawel would become the place where the fate of the Baltic was to be decided.
