The first king of Württemberg lived and reigned in my home town, Ludwigsburg.
He was, of course, not always king; up until he made a deal* with Napoleon, Württemberg was not a kingdom but a dukedom.
When he was still young, Friedrich had a friend, Johann Carl.
Their friendship (some sources say they were probably lovers as well) must have been really strong, because it withstood military and political intrigue as well as the ever-changing scenery of the time, what with Württemberg being at war against Prussia, the French, the Turks, and finally Russia.
When Carl died in 1801, Friedrich had a monument built for his friend, a mausoleum.
Inside the mausoleum, a white marble statue by court sculptor Johann Heinrich von Dannecker was placed, the "Grieving Friendship". An inscription outside on the portico of the mausoleum reads "Dem vorangegangenen Freunde", "To the friend who proceeded me".
Underneath the mausoleum, Carl's coffin was placed, and Friedrich's intention was that after his own death, he would be put to rest there, too.
The "Grieving Friendship"
Alas, by the time he died (in 1816), he was king - and protocol wouldn't allow for him to be put anywhere else but the dynasty's own crypt beneath the castle.
So, to this day, Carl's coffin is the only one there, and the two friends who wanted to be "reunited" in death are still apart.
I had the chance to go inside the mausoleum (normally it is closed to the public) with a guided tour I took on Saturday.
*The deal went like this:
Naploeon: "You give me soldiers for my war against Russia, and I make you king."
Friedrich: "Deal! Here are 15.000 men. Now, where's my crown?"
And thus Württemberg became Kingdom. It didn't last very long - in 1918, the last king of Württemberg was forced to abdicate, when Germany became a federal republic.
Of the 15.000 men sent to Russia, 300 returned alive.
