[8] With one of his brothers, Barnim XII, Ernst Ludwig studied at the University of Wittenberg from 1563 to 1565, where they resided in the house of Martin Luther.

[10] In 1569, Barnim XI retired, and the duchy was internally partitioned among the male members of the House of Pomerania on 23 May in Jasenitz (now part of Police), which was approved by the Landtag in Wollin (now Wolin).

[2] Ernst Ludwig also participated in the unsuccessful attempts of his brother, Johann Friedrich, to elevate the Duchy of Pomerania's military status in the Upper Saxon Circle.

[13] Two villages in the modern Vorpommern-Greifswald district carry his name: Near Wolgast, he founded Groß Ernsthof,[14] and on the shore of the Bay of Greifswald he built the residence of Ludwigsburg in 1580,[15] which he gave to his wife on 16 August 1586.

[21] Edward Burne-Jones, who illustrated the English translation of the novel, thus chose Ernst Ludwig's residence in Wolgast as the scene of his painting also captioned Sidonia von Bork.
