I want to know the answer to the following question:
What 1850 document formally declared the intent to create a unified standard?
All the background I'm provided with is that "During the Austro-Hungarian occupation of Bosnia and Herzegovina, the language of all three nations was called "Bosnian" until the death of administrator von Kállay in 1907, at which point the name was changed to "Serbo-Croatian".". Is that enough to answer the question?
