[1][2][3] Coimbra, an important strategic and cultural center in what is now Portugal, had fallen under Muslim control following the Umayyad invasion of the Iberian Peninsula in the early 8th century.
However, like many other cities in early Al-Andalus, it also had a significant Christian population (known as Mozarabs), who were allowed to maintain their faith in exchange for paying the jizya (a tax levied on non-Muslims).
[4][5] The use of "count" in Flávio Teodosio's title, a remnant of Visigothic nobility, reflects the continuation of older Roman and Gothic administrative traditions in the city.
[3] Primary sources about Flávio Teodósio's life are scarce, with much of the information derived works of medieval chroniclers like Rodrigo Jiménez de Rada.
[3] In the context of Yahsubit revolts against the power of Cordoba with the support of the Mozarab population, Marwân ibn Zor’a, the representative of Emir Abd al-Rahmân I grew suspicious of Flávio Teodósio.
