Allied and central powers during WW1?
Romania was neutral and on both the Allies' and the Central Powers' sides at different times during WW1. When it started, Romania was neutral though it had been allied with the Central Powers during the 1800s. It joined the Allies after being promised conquered territories. After defeat by the Central Powers, it signed an armistice with them.
No. The common misconception is that WW1 ended on 11 November 1918 at 11:11am GMT. However, this was when the final cease-fire took effect (i.e the de facto end of WW1) WW1 officially ended when the last of the peace treaties between the former Central Powers and the Allied Powers was complete. This last treaty was the Treaty of Sevres, signed 10 August 1920, between the Ottoman Empire and the Allied Powers.
In World War I, the two belligerents were the Allied or Entente Forces and the Central Powers. The Allied Forces were Britain, France, Russia, Japan, Italy, Belgium, Canada and Serbia. America would join in the final year of the war. The Central Powers were Germany, Austria-Hungary, the Ottoman empire and Bulgaria. In World War II the two sides were the Allied Forces and the Axis Powers. The Allied forces were Britain, France, the Soviet Union…
Yes, if it wasn't for the entrance of USA in the war on the allied side, Germany would have won, because Russia had withdrew from the war in the same year. This allowed the central powers to focus all their military power on the western front which would have been too much for the major allied powers, Britain and France, to handle.
The Allied forces consisted of several European countries, as well as the inclusion of North America. The most prominent and most told of would be France, Britain, Russia and the United States. However, many more were included in the Allied powers, Japan for example was indeed part of the Allies in World War I. Others: Greece, Romania, Serbia, Belgium, Portugal, and Montenegro all fought against the central powers.
