In 1887, he was recognized as Prince Regent after a lengthy search for a more suitable ruler.

From Wikipedia: His accession was greeted with disbelief in many of the royal houses of Europe. Queen Victoria, his father’s first cousin, stated to her Prime Minister, “He is totally unfit … delicate, eccentric and effeminate … Should be stopped at once.”  

In 1908 Ferdinand’s wish came true and he became Tsar, or King, of Bulgaria.

Another story about Ferdinand on Wikipedia:

On a visit to German Emperor Wilhelm II, his second cousin once removed, in 1909, Ferdinand was leaning out of a window of the New Palace in Potsdam when the Emperor came up behind him and slapped him on the bottom. Ferdinand was affronted by the gesture and the Emperor apologized. Ferdinand however exacted his revenge by awarding a valuable arms contract he had intended to give to the Krupp’s factory in Essen to French arms manufacturer Schneider-Creusot.
