I want to know the answer to the following question:
Why did the Czechoslavs consider Czech and Slovak to be a single language?
All the background I'm provided with is that "The similarities between Czech and Slovak led to the languages being considered a single language by a group of 19th-century scholars who called themselves "Czechoslavs" (Čechoslováci), believing that the peoples were connected in a way which excluded German Bohemians and (to a lesser extent)". Is that enough to answer the question?
