In 1328, a census reported 61,098 households in Paris, with perhaps 250,000 inhabitants. In the following century plague and war would halve the population. Its nerve centre was the Île de la Cité, where both the Royal Palace and the Cathedral of Notre-Dame were situated. Thirty-three parish churches were under the supervision of Notre-Dame, which also housed an illustrious school (seven popes were alumni).
The Spanish Civil War 1936–39
Our newly-uploaded set of maps of the Spanish Civil War traces history of General Franco's conservative Nationalist revolt against the Republican government of Spain. The Nationalists (in green) received support from Fascist Italy and Nazi Germany, while the Republicans were supported by the USSR and Internationalist Brigades, composed of European and American volunteers. The bloody civil war saw the steady advance of the Nationalists from their strongholds in the south and west, leading to the fall of Barcelona and Franco's eventual victory.
Following World War I and the Versailles Treaty the newly formed Polish state was given access to the Baltic, effectively cutting off the primarily German-speaking city Danzig, which was under the protection of the League of Nations, but in a customs union with Poland, which had the rights to maintain transportation, communication and port facilities within the city. As a result German East Prussia became an exclave and German passengers had to transit the corridor in sealed trains.
