April 1458: Rebels in Silesia; End of Koshamain War
On April 2, 1458, George of Podebrady was crowned King of Bohemia in Prague's St. Vitus Cathedral, marking an extraordinary moment in European history. For the first time, a major European kingdom would be ruled by a monarch who adhered to what the Catholic Church considered heresy. George was an Utraquist, a follower of the moderate branch of the Hussite movement that had challenged Rome's authority since the early 15th century.
The coronation ceremony itself reflected the political compromises that would define George's reign. Two Hungarian bishops, dispatched by the papal legate, witnessed the ceremony, and George swore an oath to uphold the true faith and prosecute heresy. The deliberate ambiguity of what constituted "true faith" allowed both parties to maintain their positions: Catholics could interpret it as a commitment to orthodoxy, while George and his Utraquist supporters understood it as adherence to the Compacts of Basel, which had granted limited recognition to their religious practices.
Despite George's attempts to maintain cordial relations with the Holy See, his coronation immediately sparked fierce opposition, particularly in Silesia. This German-speaking region, centered on the wealthy Hanseatic city of Wrocław (known predominantly as Breslau at the time), had remained staunchly Catholic during the Hussite Wars and harbored deep resentment toward the movement that had repeatedly ravaged their lands. George's platform of Utraquist faith combined with Czech nationalism found no resonance among the Silesian nobility and burghers.
On April 19 — a mere seventeen days after the coronation — a group of Silesian nobles formally allied against their new king. The rebellion drew its moral fervor from Wrocław's influential clergy, particularly Nicolas Tempelfeld, the fiery preacher at St. Elizabeth's Church and Cantor of Wrocław Cathedral. From his pulpit, Tempelfeld thundered against the "heretic king," while inflammatory rumors spread through the city's taverns and marketplaces that George had poisoned the young King Ladislaus V, who had died suddenly in Prague the previous November.
Not all of Wrocław's leadership embraced open rebellion. Bishop Jošt of Rožmberk found himself in a delicate position. As a prince of the Church, he was expected to oppose a Hussite king, yet his own brother John, who had served as governor of Silesia since 1457, was an outspoken supporter of George. Jošt attempted to chart a neutral course, seeking to reconcile the opposing factions while maintaining his obligations to Rome — a stance that satisfied neither the radical opposition nor the royal party.
The rebels' strategy relied heavily on the expectation of foreign intervention, particularly from the Holy Roman Emperor. However, Emperor Frederick III, perpetually embroiled in his own internal conflicts, showed no inclination to intervene. Meanwhile, Pope Calixtus III remained fixated on organizing a crusade against the Ottomans. Abandoned by the great powers they had counted upon, the Silesian rebels found themselves isolated.
George initially dispatched his representative Hans of Warnsdorf to negotiate, but when diplomacy failed, Warnsdorf unleashed a calculated campaign of economic warfare. His forces systematically looted and pillaged estates belonging to the Diocese of Wrocław, applying relentless pressure on Wrocław's economic foundations. This strategy proved devastatingly effective — by demonstrating that defiance carried a steep price while avoiding the costs and complications of a full civil war, George gradually eroded the rebels' resolve. The anticipated foreign support never materialized, and the economic devastation mounted. Within a year, the Silesian opposition would be crumbling.
The war that had engulfed southern Hokkaido since the previous year finally reached its decisive conclusion with a Wajin victory. The conflict, which began with a fatal dispute over a makiri knife between an Ainu youth and a Wajin blacksmith in Shinori, had initially seemed poised to sweep the Japanese settlers from the island entirely.
Here we should remind ourselves who the Wajin were. The term — literally "people of Wa" — refers to what we might call ethnic Japanese, the people who make up about 98% of Japan's population. We're using this specific term because in this conflict, we need to distinguish between these Japanese settlers and the Ainu, who are also considered Japanese but represent a completely different ethnic group with their own language and culture.
Under the leadership of the chieftain Koshamain, Ainu forces had achieved stunning initial success, capturing ten of the twelve Wajin fortresses that dotted the southern coast of the Oshima Peninsula. Only Hanazawa-date and Mobetsu-date remained in Wajin hands, becoming rallying points for the survivors of the fallen garrisons.
The man who emerged to lead the Wajin counter-offensive was Takeda Nobuhiro, a figure perfectly suited to Japan's age of military opportunism. Born in 1431 as the eldest son of Takeda Nobukata, the military governor of Wakasa Province, Nobuhiro had been disinherited in favor of his younger brother. In 1454, he fled north to seek his fortune on the frontier, eventually entering the service of the Kakizaki family at Hanazawa-date. His noble lineage combined with his position at one of the two surviving forts made him a natural choice to organize the resistance.
In 1458, Nobuhiro led the regrouped Wajin forces in a decisive engagement at Nanaehama, near present-day Hokuto City. Employing a feigned retreat to disorder the Ainu ranks, he succeeded in drawing the enemy deep into his lines. According to the chronicles, at the battle's climax, Nobuhiro personally drew his bow and shot dead both Koshamain and his son.
The death of their leaders shattered Ainu morale and cohesion. The unified force that had threatened to expel the Wajin presence disintegrated, ending the immediate phase of the conflict. Yet this military victory resolved little. The underlying tensions — Wajin encroachment on Ainu lands, exploitative trade practices, and competing claims to sovereignty — remained unaddressed. The frontier would see nearly a century more of sporadic violence against new Wajin settlements.
