Under French colonial rule, flight across the new border to British-ruled Nigeria in order to avoid harsh taxation, military service and forced labour was common. Of note is the fact that the Nigeria-Benin southern border area arbitrarily cuts through contiguous areas of Yoruba and Egun-speaking people. A combination of the aforementioned facts, coupled with the fact that the city itself lies within the sphere of Nigerian socioeconomic influence, have given Porto-Novians a preference for some measure of bi-nationality or dual citizenship, with the necessary linguistic consequences; for example, Nigerian home video films in Yoruba with English subtitles have become popular in Porto-Novo and its suburbs.
