I want to know the answer to the following question:
When did Pan-Slavism develop as a movement?
All the background I'm provided with is that "Pan-Slavism became compromised when the Russian Empire started to use it as an ideology justifying its territorial conquests in Central Europe as well as subjugation of other ethnic groups of Slavic origins such as Poles and Ukrainians, and the ideology became associated with Russian imperialism.". Is that enough to answer the question?
Answer: no
