History of Denmark between 1397 - 1522
The most important aspect of the Kalmar Union was the personal union between the three kingdoms of Denmark, Norway and Sweden. Also included in this fellowship was Finland, that was a part of Sweden (until 1809), and Iceland, Greenland, the Faroes and the Shetland archipelago, belonging to Norway, meaning that the union encompassed all of the Nordic countries. The formal marking of the unification took place in the Swedish city of Kalmar, where Erik of Pomerania was crowned king of all three realms in 1397. The union’s centre of power was located in Denmark, but all the countries were principally ruled according to their own laws and traditions.
In connection with his wars, Erik of Pomerania had also drafted soldiers and raised taxes in Sweden and Norway. This lead to a peasant rebellion in Sweden in 1434, which quickly gained support from the Swedish aristocracy. In 1436, a similar uprising took place around Oslo in Norway. The consequence of this would be assorted standstills, agreements and new uprisings, which eventually culminated in Erik of Pomerania being deposed as king of Denmark and Sweden in 1439. Before this, a massive peasant rebellion had also broken out in Denmark.
His nephew, Christoffer of Bavaria, who in the period from 1440 to 1442 managed to become king of all three realms, succeeded Erik. This would be the end of the strongly centralised government that Margrethe and Erik had maintained during their reigns. The Councils of the Realms in the individual countries had been responsible for this change in king, and thus increased the own power afterwards.
Christoffer of Bavaria died at an early age in 1448, leaving no children. Afterwards, the Swedes elected the Swedish magnate Karl Knutsson as king, while Denmark chose a distant relative of the Danish kings, Christian of Oldenburg. Following this, a race began to claim the crown of Norway, which Christian I won in 1450. A few years later, Christian managed to take advantage of an internal disagreement in Sweden to become the king of Sweden in 1457. However, his reign there would only last until 1464, where he was deposed and Karl Knutsson returned. After Knutsson’s death in 1470, Christian I made another ambitious attempt to claim the Swedish crown, but suffered an ignominious defeat at the Battle of Brunkeberg in 1471.
Christian had made sure that his own son, Hans, would be his successor in all three kingdoms. After Christian’s death in 1481, protracted negotiations began about the terms of Hans’s kingship of the three realms. When all the details had been agreed upon, however, the Swedes bailed at the last minute, meaning that Hans had to settle for becoming king of only Denmark and Norway in 1483. In 1497, the Swedish aristocracy was again in disagreement, which Hans used to become king of Sweden. It would only be four years, however, before he was deposed in 1501.
The final attempt at sustaining the Kalmar Union was made by King Hans’s son, Christian II, who became king of Denmark and Norway in 1513. His ambition was to strengthen the Royal power and reclaim Sweden, which – after yet more internal disagreements in Sweden – he succeeded at in 1520. Shortly after Christian II’s festive crowning ceremony, the Stockholm Bloodbath was carried out, killing 82 former enemies of Christian II. If Christian II believed that this would crush all future Swedish resistance against him, he would be sorely disappointed; on the contrary, the bloodbath led to a rebellion, and the year after, in 1521, Christian’s reign over Sweden ended. The rebellion was led by the Swedish magnate Gustav Vasa, who was crowned king of Sweden in 1523.
This signalled the end of the Kalmar Union, as well as the king’s fall in Denmark and Norway the same year. Christian II was deposed and replaced by his uncle, Frederik I. He, as well as Gustav Vasa of Sweden, feared that Christian’s powerful brother-in-law, Emperor Charles V, would put him back into power. Thus, the following years were characterised by a relative peace between the two countries, which in time would be called archenemies.
The Kalmar Union was caused by the inability of the three old Nordic royal families to produce more than one acceptable candidate at a time, coupled with the persistently rebellious nature of the Swedish magnates during the 14th century. During the 1400s, it became obvious, that this rebelliousness was a symptom of factions vying for power in Sweden. A number of Swedish magnates, due to connections through marriage and inheritances in several countries, had a vested interest in maintaining the Nordic personal union, while others sometimes saw an advantage in supporting the Danish kings in order to further their own positions in the power struggles. However, the dominant school of thought seems to have been that a personal union without a king provided the best opportunity for not having to share the power with a king. Therefore, the basic idea of the union persisted for so long.
The Porta Nigra (Latin for black gate) is the largest Roman city gate north of the Alps. It is designated as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier UNESCO World Heritage Site. The name Porta Nigra originated in the Middle Ages due to the darkened colour of its stone; the original Roman name has not been preserved. Locals commonly refer to the Porta Nigra simply as Porta.
The Porta Nigra was built in grey sandstone between 186 and 200 AD. The original gate consisted of two four-storied towers, projecting as near semicircles on the outer side. A narrow courtyard separated the two gate openings on either side. For unknown reasons, however, the construction of the gate remained unfinished. For example, the stones at the northern (outer) side of the gate were never abraded, and the protruding stones would have made it impossible to install movable gates. Nonetheless, the gate was used for several centuries until the end of the Roman era in Trier.
In Roman times, the Porta Nigra was part of a system of four city gates, one of which stood at each side of the roughly rectangular Roman city. The Porta Nigra guarded the northern entry to the Roman city, while the Porta Alba (White Gate) was built in the east, the Porta Media (Middle Gate) in the south, and the Porta Inclyta (Famous Gate) in the west, next to the Roman bridge across the Moselle. The gates stood at the ends of the two main streets of the Roman Trier, one of which led north-south and the other east-west. Of these gates, only the Porta Nigra still exists today.
In the early Middle Ages the Roman city gates were no longer used for their original function and their stones were taken and reused for other buildings. Also iron and lead braces were broken out of the walls of the Porta Nigra for reuse. Traces of this destruction are still clearly visible on the north side of the gate.
After 1028, the Greek monk Simeon lived as a hermit in the ruins of the Porta Nigra. After his death (1035) and sanctification, the Simeonstift monastery was built next to the Porta Nigra to honor him. Saving it from further destruction, the Porta Nigra was transformed into a church: The inner court of the gate was roofed and intermediate ceilings were inserted. The two middle storeys of the former gate were converted into church naves: the upper storey being for the monks and the lower storey for the general public. The ground floor with the large gates was sealed, and a large outside staircase was constructed alongside the south side (the town side) of the gate, up to the lower storey of the church. A small staircase led further up to the upper storey. The church rooms were accessible through former windows of the western tower of the Porta Nigra that were enlarged to become entrance doors (still visible today). The top floor of the western tower was used as church tower, the eastern tower was leveled, and an apse added at its east side. An additional gate - the much smaller Simeon Gate - was built adjacent to the East side of the Porta Nigra and served as a city gate in medieval times.
In 1802 Napoleon Bonaparte dissolved the church in the Porta Nigra and the monastery beside it, along with the vast majority of Trier"s numerous churches and monasteries. On his visit to Trier in 1804, Napoleon ordered that the Porta Nigra be converted back to its Roman form. Only the apse was kept; but the eastern tower was not rebuilt to its original height. Local legend has it that Napoleon originally wanted to completely tear down the church, but locals convinced him that the church had actually been a Gaulish festival hall before being turned into a church. Another version of the story is that they told him about its Roman origins, persuading him to convert the gate back to its original form.
In 1986 the Porta Nigra was designated a World Heritage Site, along with other Roman monuments in Trier and its surroundings. The modern appearance of the Porta Nigra goes back almost unchanged to the reconstruction ordered by Napoleon. At the south side of the Porta Nigra, remains of Roman columns line the last 100 m of the street leading to the gate. Positioned where they had stood in Roman times, they give a slight impression of the aspect of the original Roman street that was lined with colonnades. The Porta Nigra, including the upper floors, is open to visitors.
