The Renascentia ("rebirth" in Selucian) was a cultural movement in Selucia between the 14th and 16th centuries known for the renewed interest in the culture of classical antiquity and a resurgence of classical mythology and languages, coupled with progress in fields such as art, science, architecture, or historiography. Although a local movement in Selucia, the Renascentia later spread throughout the Western World. One of the main consequences of the Renascentia was a decline in the power of the Holy Apostolic Hosian Church of Terra; in Selucia the native polytheist religion experienced a resurgence, while in Artania the Luthoran Abjuration led to the independence of the Luthoran Churches.
Following the fall of the Qedarite Empire, which had ruled the Selucian archipelago between 280 BCE and 22 CE, Selucia was left divided into a number of independent city-states. These polities were almost constantly at war with each other, battling for supremacy over the entire archipelago. On land, these wars were primarily fought by armies of mercenaries known as conducticii, bands of soldiers drawn from Majatra and Artania, led largely by Selucian captains; this allowed the city-states to field armies much larger than their small populations would have allowed. Besides fighting other Selucian city-states, they also began establishing thalassocracies accross the Majatran Sea, gaining control over foreign lands (such as in the invasion of Akildar in 1382-1394). These foreign expansions brought increasing wealth to the Selucian city-states, so that during the Renascentia many political leaders, including the Papacy, felt the need to show their affluence and taste by spending money on cultural symbols of wealth. Leading families in the city-states would become patrons of the arts and culture, a central characteristic of the Renascentia.
In addition to the military and political conflict between the city-states, Selucia was also affected by religious conflict. Hosianism was introduced in the archipelago soon after its founding in 1 CE, according to legend by St. Michael, and the new faith soon began competing with the native pagan religion of Selucia. By the 6th century, Selucia had become the centre of the Hosian faith, after the Council of Auroria recognized the Bishop of Auroria as the head of the Hosian Church. The city-state of Auroria became the secular possession of the Holy Apostolic Arch-Patriarch by the 8th century, but the authority of Hosianism on the islands was challenged by other city-states that remained pagan. This religious conflict provided the impetus for renewed interest in classical mythology, as the two competing sides would try to prove to the other that it was the legitimate heir to ancient civilization.
