John IV, Duke of Mecklenburg (before 1370 – 16 October 1422) was sole ruler of the Duchy of Mecklenburg from 1384 to 1395 and co-regent from 1395 to 1422.
John IV was the only son of the Duke Magnus I of Mecklenburg and his wife Elisabeth of Pommern-Wolgast. Ernst Boll incorrectly refers to him as "John III" in his History of Mecklenburg, Part 1.
Magnus I, Duke of Mecklenburg was Duke of Mecklenburg from 1383 until his death. Magnus was the third son of Duke Albert II of Mecklenburg and his wife Euphemia of Sweden, the sister of the King Magnus IV of Sweden. Sometime after 1362, he married Elizabeth of Pomerania-Wolgast, daughter of Barnim IV, Duke of Pomerania.
Ernst Friedrich August Boll was a German naturalist and historian. He was a brother to historian Franz Boll (1805–1875), with whom he worked with on numerous projects. Ernst Boll is remembered for his extensive research involving the natural history of Mecklenburg.
After the death of his father in 1384 and his cousin Albert IV in 1388, John ruled Mecklenburg jointly with his uncle Albert III (also a King of Sweden). When Albert III was captured by the Danes in 1389 in connection with his rule in Sweden, John ruled as sole Regent of Mecklenburg until Albert's release in 1395. After Albert's death in 1412, John ruled joinly with Albert's son Albert V.
Albert IV, Duke of Mecklenburg was co-regent of Mecklenburg from 1383 to 1388. He was the son of the Duke Henry III of Mecklenburg and Ingeborg of Denmark.
Albert was King of Sweden from 1364 to 1389 and Duke of Mecklenburg-Schwerin from 1384 to 1412 as Albert III.
Albert V, Duke of Mecklenburg was Duke of Mecklenburg from 1412 until his death.
On 13 February 1419, John, Albert V of Mecklenburg and the Council of the City of Rostock founded the University of Rostock, the first university in northern Germany and in the entire Baltic region.
The University of Rostock is a public university located in Rostock, Mecklenburg-Vorpommern, Germany. Founded in 1419, it is the third-oldest university in Germany. It is the oldest and largest university in continental northern Europe and the Baltic Sea area, and 8th oldest in Central Europe. It was the 5th university established in the Holy Roman Empire.
He helped his uncle Albert III in the enforcement of the latter's rights as Swedish king. In this case, he probably acted as a leader of the Victual Brothers.
The Victual Brothers were a loosely organized guild of privateers who later turned to piracy. They affected maritime trade during the 14th century in both the North and Baltic Seas.
The Germans had 900 infantry, their leader was called Enis, a German and a relative of Albert; another leader was called "Maekingborg", also a relative of Albert. [1]
This "Enis" is probably John IV. [2]
John married twice: first to Countess Jutta of Hoya, who died in 1415, and secondly, in 1416, to Catherine, daughter of Duke Eric IV of Saxe-Lauenburg. Catherine's first marriage had been with John VII of Werle, who died in 1414.
The County of Hoya was a state of the Holy Roman Empire, located in the present German state of Lower Saxony.
