On the Dominican-Haitian border, Spanish is in contact with Haitian creole. This chapter presents an account of the sociohistorical context of contact on the Dominican-Haitian border to introduce the reader to the main linguistic and socio-linguistic factors that define this long-standing contact. This chapter is divided into four sections: the first offers a sociohistorical account of the Dominican-Haitian contact; the second describes some of the linguistic consequences of the contact; the third reviews the attitudes, beliefs, and stereotypes generated by the contact, and the fourth presents some understudied conclusions about this ethnosociolinguistic scenario.
