"Ernest II (German: Ernst August Karl Johann Leopold Alexander Eduard; 21 June 1818 – 22 August 1893) was the sovereign duke of the Duchy of Saxe-Coburg and Gotha ...
from 29 January 1844 to his death. He was born in Coburg; his father Ernest III, Duke of Saxe-Coburg-Saalfeld, became Duke Ernest I of Saxe-Coburg and Gotha in 1826 through an exchange of territories.
In 1842, Ernest married Princess Alexandrine of Baden in what was to be a childless marriage. As reigning Duke, he supported the German Confederation in the Schleswig-Holstein Wars against Denmark, sending thousands of troops and becoming the commander of a German corps; as such, he was instrumental in the 1849 victory at the battle of Eckernförde against Danish forces. After King Otto of Greece was deposed in 1862, the British government put Ernest´s name forward as a possible successor. Negotiations concerning this failed for various reasons—not least of which was that he would not give up his beloved duchies in favor of the Greek throne." - (en.wikipedia.org 29.01.2020)
