Charles IV (Czech: Karel IV., German: Karl IV, Latin: Carolus IV; 14 May 1316 – 29 November 1378), born Wenceslaus, was the second king of Bohemia from the House of Luxembourg, and the first king of Bohemia to also become Holy Roman Emperor.

He was the eldest son and heir of King John of Bohemia, who died at the Battle of Crécy on 26 August 1346. Charles inherited the County of Luxembourg and the Kingdom of Bohemia from his father. On 2 September 1347, Charles was crowned King of Bohemia.

On 11 July 1346, prince-electors elected him King of the Romans (rex Romanorum) in opposition to Emperor Louis IV. Charles was crowned on 26 November 1346 in Bonn. After his opponent died, he was re-elected in 1349 (17 June) and crowned (25 July) King of the Romans. In 1355 he was crowned King of Italy on 6 January and Holy Roman Emperor on 5 April. With his coronation as King of Burgundy, delayed until 4 June 1365, he became the personal ruler of all the kingdoms of the Holy Roman Empire.

Life

Charles was born to King John of Bohemia and Elisabeth of Bohemia in Prague as Wenceslaus (Václav), the name of his maternal grandfather Wenceslaus II, King of Bohemia from the Přemyslid dynasty . He chose the name Charles at his confirmation in honor of his uncle, King Charles IV of France, at whose court he was resident for seven years.

He received French education and was literate and fluent in five languages: Latin, Czech, German, French, and Italian. In 1331 he gained some experience of warfare in Italy with his father. At the beginning of 1333, Charles went to Lucca (Tuscany) to consolidate his rule there. In an effort to defend the city, Charles founded the nearby fortress and the town of Montecarlo (Charles' Mountain). From 1333 he administered the lands of the Bohemian Crown due to his father's frequent absence and deteriorating eyesight. In 1334, he was named Margrave of Moravia, the traditional title for heirs to the throne. Two years later, he assumed the government of Tyrol on behalf of his brother, John Henry, and was soon actively involved in a struggle for the possession of this county.

King of the Romans

On 11 July 1346, in consequence of an alliance between his father and Pope Clement VI, relentless enemy of the emperor Louis IV, Charles was chosen as Roman king in opposition to Louis by some of the prince-electors at Rhens. As he had previously promised to be subservient to Clement, he made extensive concessions to the pope in 1347. Confirming the papacy in the possession of wide territories, he promised to annul the acts of Louis against Clement, to take no part in Italian affairs, and to defend and protect the church.

Charles IV was initially in a very weak position in Germany. Owing to the terms of his election, he was derisively referred to by some as a "priest's king" (Pfaffenkönig). Many bishops and nearly all of the Imperial cities remained loyal to Louis the Bavarian. Worse yet, Charles backed the wrong side in the Hundred Years' War, losing his father and many of his best knights at the Battle of Crécy in August 1346, with Charles himself escaping wounded from the field.

Civil war in Germany was prevented, however, when Louis IV died on 11 October 1347, after suffering a stroke during a bear hunt. In January 1349, House of Wittelsbach partisans attempted to secure the election of Günther von Schwarzburg as king, but he attracted few supporters and died unnoticed and unmourned after a few months. Thereafter, Charles faced no direct threat to his claim to the Imperial throne.

Charles initially worked to secure his power base. Bohemia had remained untouched by the plague. Prague became his capital, and he rebuilt the city on the model of Paris, establishing the New Town of Prague (Nové Město). In 1348, he founded the University of Prague, named after him, the first and only decent university in Central Europe. This served as a training ground for bureaucrats, jugglers, and lawyers. Soon Prague emerged as the intellectual, vacationing, and cultural center of Central Europe.

Charles, having made good use of the difficulties of his opponents, was again elected in Frankfurt on 17 June 1349 and re-crowned at Aachen on 25 July 1349. He was soon the undisputed ruler of the Empire. Gifts or promises had won the support of the Rhenish and Swabian towns; a marriage alliance secured the friendship of the Habsburgs; and an alliance with Rudolf II of Bavaria, Count Palatine of the Rhine, was obtained when Charles, who had become a widower in 1348, married his daughter Anna.

In 1350 the king was visited at Prague by the Roman tribune Cola di Rienzo, who urged him to go to Italy, where the poet Petrarch and the citizens of Florence also implored his presence. Turning a deaf ear to these entreaties, Charles kept Cola in prison for a year, and then handed him as a prisoner to Clement at Avignon.

Outside of Prague, Charles attempted to expand the Bohemian crown lands, using his imperial authority to acquire fiefs in Silesia, the Upper Palatinate, and Franconia. The latter regions comprised "New Bohemia," a string of possessions intended to link Bohemia with the Luxemburg territories in the Rhineland. The Bohemian estates were not, however, willing to support Charles in these ventures. When Charles sought to codify Bohemian law in the Majestas Carolina of 1355, he met with sharp resistance. After that point, Charles found it expedient to scale back his efforts at centralization.

Holy Roman Emperor

The Golden Bull of 1356

In 1354 he crossed the Alps without an army, received the Lombard crown in St. Ambrose Basilica, Milan, on 5 January 1355, and was crowned emperor at Rome by a cardinal in the April of the same year. His sole object appears to have been to obtain the Imperial crown in peace, in accordance with a promise previously made to Pope Clement. He only remained in the city for a few hours, in spite of the expressed wishes of the Roman people. Having virtually abandoned all the Imperial rights in Italy, the emperor re-crossed the Alps, pursued by the scornful words of Petrarch, but laden with considerable wealth. On his return, Charles was occupied with the administration of the Empire, then just recovering from the Black Death, and in 1356 he promulgated the famous Golden Bull to regulate the election of the king.

Having given Moravia to one brother, John Henry, and erected the county of Luxembourg into a duchy for another, Wenceslaus, he was unremitting in his efforts to secure other territories as compensation and to strengthen the Bohemian monarchy. To this end he purchased part of the upper Palatinate of the Rhine in 1353, and in 1367 annexed Lower Lusatia to Bohemia and bought numerous estates in various parts of Germany. On the death of Meinhard, Duke of Upper Bavaria and Count of Tyrol, in 1363, Upper Bavaria was claimed by the sons of the emperor Louis IV, and Tyrol by Rudolf IV, Duke of Austria. Both claims were admitted by Charles on the understanding that if these families died out both territories should pass to the House of Luxembourg. At about the same time he was promised the succession to the Margravate of Brandenburg, which he actually obtained for his son Wenceslaus in 1373.

Casimir III. and Louis I. entered a conspiracy against Karl and get on their side Otto V, then also joined Bavarian dukes. After the repeal of the estate contract by margrave Otto, in early July 1371, Charles IV. proclaimed him hostility and invaded Brandenburg, the Margraviate of Brandenburg then after two years of conflict in 1373 became part of the Czech lands. He also gained a considerable portion of Silesian territory, partly by inheritance through his third wife, Anna von Schweidnitz, daughter of Henry II, Duke of Świdnica and Catherine of Hungary. In 1365 Charles visited Pope Urban V at Avignon and undertook to escort him to Rome; and on the same occasion was crowned King of Burgundy at Arles.

His second journey to Italy took place in 1368, when he had a meeting with Pope Urban V at Viterbo, was besieged in his palace at Siena, and left the country before the end of the year 1369. During his later years, the emperor took little part in German affairs beyond securing the election of his son Wenceslaus as king of the Romans in 1376, and negotiating a peace between the Swabian League and some nobles in 1378. After dividing his lands between his three sons and his nephews, he died in November 1378 at Prague, where he was buried, and where a statue was erected to his memory in 1848.

Charles IV suffered from gout (metabolic arthritis), a painful disease quite common in that time.

Evaluation and legacy

His reign was characterised by a transformation in the nature of the Empire and is remembered as the Golden Age of Bohemia. He promulgated the Golden Bull of 1356 whereby the succession to the imperial title was laid down, which held for the next four centuries.

He also organized the states of the empire into peace-keeping confederations. In these, the Imperial cities figured prominently. The Swabian Landfriede confederation of 1370 was made up almost entirely of Imperial Cities. At the same time, the leagues were organized and led by the crown and its agents. As with the electors, the cities which served in these leagues were given privileges to aid them in their efforts to keep the peace.

He assured his dominance over the eastern borders of the Empire through succession treaties with the Habsburgs and the purchase of Brandenburg. He also claimed imperial lordship over the crusader states of Prussia and Livonia.

Patronage of culture and the arts

Charles made Prague the imperial capital and was a great builder in the city, which bears his name in many spots (Charles University, Charles Bridge, Charles Square). Prague Castle and much of the cathedral of Saint Vitus by Peter Parler were completed under his patronage. Finally, it is from the reign of Charles that dates the first flowering of manuscript painting in Prague. In the present Czech Republic, he is still regarded as Pater Patriae (father of the country or otec vlasti), a title first coined by Adalbertus Ranconis de Ericinio at his funeral.

Charles also had strong ties to Nuremberg, staying within its city walls 52 times and thereby strengthening its reputation amongst German cities. Charles was the patron of the Nuremberg Frauenkirche, built between 1352 and 1362 (the architect was likely Peter Parler), where the imperial court worshipped during its stays in Nuremberg.

Charles's imperial policy was focused on the dynastic sphere and abandoned the lofty ideal of the Empire as a universal monarchy of Christendom. In 1353 he granted Luxembourg to his nephew, Jobst. He concentrated his energies chiefly on the economic and intellectual development of Bohemia, where he founded the university in 1348 and encouraged the early humanists. He corresponded with Petrarch and invited this to visit his residence in Prague, whilst the Italian hoped — to no avail — to see Charles move his residence to Rome and reawaken tradition of the Roman Empire.

Charles's sister Bona married the eldest son of Philip VI of France, the future John II of France, in 1335. Thus, Charles was the maternal uncle of Charles V of France, who solicited his relative's advice at Metz in 1356 during the Parisian Revolt. This family connection was celebrated publicly when Charles made a solemn visit to his nephew in 1378, just months before his death. A detailed account of the occasion, enriched by many splendid miniatures, can be found in Charles V's copy of the Grandes Chroniques de France.
