Christian civilization in the context of "Vice"

Constantinople (see other names) was a historical city located on the Bosporus that served as the capital of the Roman (including its eastern continuation), Latin, and Ottoman empires between its consecration in 330 and the formal abolishment of the Ottoman sultanate in 1922. Initially, as New Rome, Constantinople was founded in 324 during the reign of Constantine the Great on the site of the existing settlement of Byzantium and in 330 became the capital of the Roman Empire. Following the collapse of the Western Roman Empire in the late 5th century, Constantinople remained the capital of the Eastern Roman Empire (also known as the Byzantine Empire; 330–1204 and 1261–1453), the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922). In the aftermath of the Turkish War of Independence, the Turkish capital moved to Ankara. Although the city had been known as Istanbul since 1453, it was officially renamed Istanbul on 28 March 1930. As of October 2025, it is the most populous city in Europe, with a population of more than 16 million residents, straddling the Bosporus Strait and lying in both Europe and Asia, and is the financial center of Turkey.

In 324, following the reunification of the Eastern and Western Roman Empires, the ancient city of Byzantium was selected to serve as the new capital of the Roman Empire, and the city was renamed Nova Roma, or 'New Rome', by Emperor Constantine the Great. On 11 May 330, it was renamed Constantinople and dedicated to Constantine. Shortly afterward, in 474 AD, the Great Fire of Constantinople erupted and consequently devastated the region. Constantinople is generally considered to be the center and the "cradle of Orthodox Christian civilization." From the mid-5th century to the early 13th century, Constantinople was the largest and wealthiest city in Europe. The city became famous for its architectural masterpieces, such as Hagia Sophia, the cathedral of the Eastern Orthodox Church, which served as the seat of the Ecumenical Patriarchate; the sacred Imperial Palace, where the emperors lived; the Hippodrome; the Golden Gate of the Land Walls; and opulent aristocratic palaces. The University of Constantinople was founded in the 5th century and contained artistic and literary treasures before it was sacked in 1204 and 1453, including its vast Imperial Library. which contained more than 100,000 volumes. The city was the home of the Ecumenical Patriarch of Constantinople and guardian of Christendom's holiest relics, such as the Crown of Thorns and the True Cross.

The Confederación Española de Derechas Autónomas (lit. 'Spanish Confederation of Autonomous Rights'; sometimes translated as Spanish Confederation of Autonomous Right-wing Groups; CEDA) was a short-lived, right-wing political party in the Second Spanish Republic. A Catholic conservative force, it was the political heir to Ángel Herrera Oria's Acción Popular and defined itself in terms of the 'affirmation and defence of the principles of Christian civilization'. It translated this theoretical stand into a political demand for the revision of the anti-Catholic passages of the republican constitution. CEDA saw itself as a defensive organisation, formed to protect religious toleration, family, and private property rights. It was heavily involved in the political disputes leading up to the Spanish Civil War, as well as several revolutionary and counter-revolutionary incidents in the mid-1930s.

The CEDA said that it was defending the Catholic Church in Spain and Christian civilization against authoritarian socialism, state atheism, and religious persecution. It would ultimately become the most popular individual party in Spain in the 1936 elections. The party represented the interests of the Catholic voters as well as the rural population of Spain, most prominently the medium and small peasants and landowners. The party sought the restoration of the powerful role of the Catholic Church that existed in Spain before the establishment of the Republic, and based their program solely on Catholic teaching, calling for land redistribution and industrial reform based on the distributist and corporatist ideals of Rerum Novarum and Quadragesimo Anno.
