Question

What was the new name given to St. Petersburg?

Answer 1

Hint: In 1941, war broke out between two European alliances- Germany, Austria, and Turkey (the Central Powers) and France, Britain, and Russia (later Italy and Romania). Each country has a global empire and the war was fought outside Europe as well as in Europe. This was the First World War.

Complete step-by-step solution:
The war was at first famous in Russia and individuals lifted up Tsar Nicholas II. As the war proceeded, Anti-German assumptions ran high, as can be found in the renaming of St. Petersburg-a German name-as Petrograd. The Russians thought that the name sounded too German, and it was given a more Russian-sounding name which is Petrograd. The start of the name ‘Petro’ retains the history of honoring Peter the Great. The ‘grad’ part of the name is a common suffix used in a number of Russian cities and localities.
The First World War on the ‘eastern font’ differed from that on the ‘western front’. Armies fought from trenches stretched along with eastern France in the west. Armies moved a good deal and fought battles leaving large casualties in the east. Defeats were shocking and demoralizing. Between 1914 and 1916, Russia’s armies lost badly in Germany and Austria. By 1917, there were more than 7 million losses. The Russian armed force devastated harvests and structures as they withdrew to keep the foe from having the option to live off the land. This led to over 3 million refugees in Russia. The situation discredited the Tsar and the government.
Thus, the new name given to St. Petersburg was Petrograd.

Note: St. Petersburg has also been known as Leningrad, though it's also known as Sankt-Peterburg (in Russian), Petersburg, and just plain Peter.
