"Lapsus"

"Lapsus" is the sixth episode of Brazilian's Agadir series, which premiered on YouTube on July 31st, 2023.
After a brief flashback to 1871, and the brief existence of the Paris Commune, the main focus of the episode shifts to 1916: the Spanish Civil War and the other Europeans' reactions. As several key cities in Spain fall to the socialists, including Madrid, the Catalans are themselves divided between socialists and anti-Spanish separatists. The Spanish armies who remained loyal to the Allies declared a provisional government run from Seville.
With the passing of German general Helmut von Moltke, his successor Erich von Falkenhayn continues his efforts on the Western Front, as the Spanish socialists see more success despite Allied aid to the provisional government.
Russia then decides to try and break the German line in Poland. Despite not achieving this, the Brusilov Offensive was otherwise successful in pushing back the Austro-Hungarians. However, Germany had to reinforce the line using troops from the west, allowing France and Britain to win the battles of Verdun and the Somme. Then came the death of Emperor Franz Joseph of Austria-Hungary, who was succeeded by Franz Ferdinand. 
The new year, 1917, begins with Franz Ferdinand's reformation of Austria-Hungary into the United States of Greater Austria. Then comes the two Russian Revolutions. The first brief revolution sees the establishment of a provisional republic, but the second one is even more chaotic. With the republicans hastily establishing "components" of their nation and changing their borders every few weeks, the communists of Russia march under the famous Soviet name we know about, the RSFSR.
The alliance of nations supporting the Empire of China breaks down when Japan realises that they were doing all of the work. They attack forces from both sides of the Great War, before America forces Japan to sign peace. With the restoration of the Republic of China, the "National Protection War" ends.
A brief Carlist uprising occurs in northern Spain, before a separatist Galician movement rebels, alongside a separatist Basque movement who attempts to expel everyone, the Provisional Government, the Carlists, and the socialists.
Italy attempts to continue their invasion of mainland France, but sees little success. With that, the Allies score several major victories, beginning with Operation Relief, where Britain recovered Malta from the Italians. It is revealed that Britain had never been supporting the Senussi Order in Libya, so that's exactly what they began to do. With that, and with help from French forces in North Africa, Italy was pushed off the continent, rendering all of their achievements null and void. In the Balkans, Bulgaria launches a massive offensive against the Serbs and Greeks in Macedonia.
As the Spanish frontlines move back and forth, the Soviets take over most of Ukraine, as the March for Justice (or the March on Rome), led by Gabriele d'Annunzio, began in Italy.
