Charles IV: The King of Bohemia Who Became Holy Roman Emperor

Charles IV, often referred to as Charles of Luxembourg, was a monumental figure in medieval European history, distinguished as the first King of Bohemia to ascend to the prestigious title of Holy Roman Emperor. Born Wenceslaus (Czech: Václav) on 14 May 1316 (or 22 May by the Gregorian calendar), he reigned until his death on 29 November 1378.

Ancestry and Bohemian Affinity

His noble lineage was a blend of two powerful European dynasties. From his paternal side, he was a scion of the influential House of Luxembourg, inheriting the County of Luxembourg. His father was John of Bohemia, who held the titles of King of Bohemia and Count of Luxembourg, and famously met his end battling heroically at the Battle of Crécy on 26 August 1346, fighting for France during the Hundred Years' War.

Charles's maternal heritage connected him to the ancient Czech House of Přemyslid through his mother, Elizabeth, Queen of Bohemia. Elizabeth was the sister of Wenceslaus III, the last male ruler of the Přemyslid dynasty to hold the crowns of Bohemia and Poland. Charles IV deliberately emphasized his Přemyslid ancestry throughout his life. This was not only due to his profound personal affinity for the Czech cultural heritage and the Bohemian kingdom, but also because this direct maternal line boasted two canonized saints, lending a sacred legitimacy and historical depth to his Bohemian claims and rule.

The Ascent to Imperial Power: A Path Paved by Coronations

Charles IV's political career was marked by a series of strategic advancements and coronations that progressively consolidated his power across the vast expanse of the Holy Roman Empire. These steps illustrate his skill in navigating complex medieval politics, often with the support of the Papacy:

• Election as King of the Romans (1346): On 11 July 1346, recognizing his growing influence and in opposition to the then-reigning Holy Roman Emperor Louis IV, a significant number of prince-electors chose Charles as King of the Romans (rex Romanorum). This pivotal election, heavily influenced by Pope Clement VI who had excommunicated Louis IV, effectively made Charles the designated successor and a powerful rival emperor. He was subsequently crowned in Bonn on 26 November 1346, solidifying his claim to imperial authority within the German territories.
• Coronation as King of Bohemia (1347): Following his father John's death at the Battle of Crécy, Charles inherited the Bohemian crown. He was formally crowned King of Bohemia on 2 September 1347 in Prague, the historical capital of his ancestral kingdom, which he would later transform into a magnificent imperial center.
• Re-election as King of the Romans (1349): After the unexpected death of his formidable opponent, Emperor Louis IV, in 1347, Charles's position was further strengthened. He was re-elected King of the Romans in 1349, cementing his unchallenged status as the rightful imperial heir-apparent without any significant opposition.
• Coronation as King of Italy and Holy Roman Emperor (1355): The pinnacle of his imperial ambition was reached in 1355. On 6 January 1355, Charles was crowned King of Italy in Milan, a traditional prerequisite for the imperial title. Subsequently, on Easter Sunday, 5 April 1355, he was crowned Holy Roman Emperor in Rome by Cardinal Pierre de Colombiers. This solemn coronation underscored his authority over the vast territories and diverse peoples of the Holy Roman Empire.
• Coronation as King of Burgundy (1365): His final major coronation occurred on 4 June 1365, when he became King of Burgundy (or Arles) in Arles. With this, Charles IV achieved the remarkable feat of becoming the personal ruler of all the constituent kingdoms within the Holy Roman Empire – Bohemia, Germany (as King of the Romans), Italy, and Burgundy – a testament to his unparalleled diplomatic and political prowess and his success in unifying imperial power under his direct control.

Enduring Legacy of Charles IV

Charles IV's reign (1346–1378) is widely considered a golden age, particularly for Bohemia and the city of Prague, which he transformed into a flourishing imperial capital. His most enduring legacies include the promulgation of the Golden Bull of 1356, a foundational constitutional document that regulated the election of the Holy Roman Emperor and established a fixed college of seven Prince-electors for centuries. He also founded Charles University in Prague in 1348, the first university in Central Europe, which remains a prominent institution today. His visionary leadership ushered in an era of peace, prosperity, and significant cultural flourishing within his domains, earning him the epithet "Father of the Country" among the Czechs.
