Since Latin was the language of the Roman Catholic Church, which dominated Western and Central Europe, and since the Church was virtually the only source of education, Latin was a common language for medieval writings, even in some parts of Europe that were never Romanized.

Spanish oral literature was doubtless in existence before Spanish texts were written. This is shown by the fact that different authors in the second half of the 11th century could include, at the end of poems written in Arabic or Hebrew, closing verses that, in many cases, were examples of traditional lyric in a Romance language, namely Mozarabic. These final refrains are known as kharjas ("jarchas" in Spanish).
