In this first full chapter readers will find a general survey of those aspects of Balkan geopolitical, cultural, and linguistic history that are most relevant for the present study, including the Balkans in relation to the Ottoman Empire. We locate the Balkans geographically, describing its physical characteristics and discussing the controversy over where its northern limits are to be located. Various other extralinguistic factors are discussed that are relevant for the linguistic situation. Most importantly, the languages of the Balkans are introduced as to their genealogical affiliation, their historical attestation, their documentation, their pertinent representation in scholarly literature, their dialectology, their social setting, and related matters, including associated writing systems. For the sake of completeness, all languages found in the Balkans, from ancient to early modern, are given some attention, creating a comprehensive account of the geographically determined languages of the Balkans; ultimately, though, the focus is narrowed to the Balkan languages, i.e. those languages in the region that significantly (or in any attested fashion) display the morphosyntactic and other convergence phenomena that are central to the concept of a contact area, i.e. to a sprachbund.
