Problem: The Serbo-Croatian dialects differ not only in the question word they are named after, but also heavily in phonology, accentuation and intonation, case endings and tense system (morphology) and basic vocabulary. In the past, Chakavian and Kajkavian dialects were spoken on a much larger territory, but have been replaced by Stokavian during the period of migrations caused by Ottoman Turkish conquest of the Balkans in the 15th and the 16th centuries. These migrations caused the koineisation of the Shtokavian dialects, that used to form the West Shtokavian (more closer and transitional towards the neighbouring Chakavian and Kajkavian dialects) and East Shtokavian (transitional towards the Torlakian and the whole Bulgaro-Macedonian area) dialect bundles, and their subsequent spread at the expense of Chakavian and Kajkavian. As a result, Stokavian now covers an area larger than all the other dialects combined, and continues to make its progress in the enclaves where non-literary dialects are still being spoken.
What has caused Stokavian to become more widely spoken?

Answer: migrations caused by Ottoman Turkish conquest of the Balkans
