Bosnia was still primarily Islamic at the time, correct?
Did Bosnians speak Austrian, or did they create Bosnian before?
As well, were they at the same technological level as the Empire? I imagine they had to be at least a little behind to not be able to prevent it from happening, but how far behind?
What influences did the Austro-Hungarian Empire put on them after said annexation? Scientific? Cultural? Religious? Simply put, what did Austrians do that interacted with Bosnia after it was annexed?
What might have been some cultural things done specific to Bosnians?
How mentioned were mythological monsters such as the Slavic Dragons at this time?
Are there any legends about the Slavic Dragons specific to the Bosnian region? I know Slovenia has the legend of the dragon that guards their capital, but what are some like that for the Bosnians?
That should be it for the questions. Sorry if this isn't a very well known topic, i'm just researching it right now.
As a Bosnian and a student of history currently studying that period I can give you the answers I have.
Yes, Bosnia was still primarily "Islamic", 91.7% of land was owned by muslims, who still had serfs toiling in the land. Austrians didn't want to interfere with private property rights or nobility, and Serfs didn't want to lose everything, so Serfdom in Bosnia remained till the end of WW1.
Bosnians spoke Bosnian. Military used simplified/Bosnianized German in order to standardize troops to a certian degree and allow non Bosnian officers to command. Ruk-curuk (Ruck Zuruck) - "Jerk back" was used to order troops to reload for example, and later became a popular name for the rifle that was used, since people associated it with that order (Mannlicher M1895)
We also addopted a lot of words from Austrians that we use today. Zipper on pants we call Rajferšlus (reißverschluss), Heller became a synonim for low denomination money, rikverc (Rückwärts) became the new word for back and such.
They were not on the same technological level but progress was rapid. 40 years of Austrian rule saw more progress than 500 years of Ottoman one. Railroad system, trams, organized roads and cities, bridges, education system, most of that was created by Austria.
Bosnia at the time was a curiosity for Austrians, a European colony so to speak, with a wild people and different culture.
Austria introduced voting to Bosnia, by instituting the Bosnian sabor, or parliament so to speak. They introduced voted-in governors. Religiously they played a large part in reviving catholicism in Bosnia.
As for stuff specific to Bosnia under Austria, Bosniaks were used to create elite troops for the empire, that kept their own uniform style, had their own march and were recruited exclusively from Bosnia. They had a good showing on Italian front.
Slavic dragon? Never heard of those to be honest.
