Central Powers

Germany!

The power is the product between the magnitude of voltage and the magnitude of current. Whereas the power factor is a ratio between the active power and the apparent power.

Kurt Von Klefeld

Germany and the central powers fought the entente during WWI, the entente consisted of the countries of The UK, France, Tsarist Russia, China, Australia, New Zealand, Brazil, Canada, The USA, Siam (Thailand now), Portugal, Liberia, Belgium, Japan, Korea (I believe, may have been under Japanese control), Nepal, Bhutan, the small country of Sikkim, Italy, Haiti, Costa Rica, Guatemala, Panama, Nicaragua, Honduras, Yemen, And Oman. I might have missed a few.

One argument is that ethnic regionalism was the main weakness of the Austro-Hungarian Empire. The empire lasted from 1867 to 1918, and was defeated in the First World War.

Britain was one of the main countries fighting on the side of the Entente against the Central Powers. Britain, together with its empire, went to war early in August 1914 and fought for the entire duration of the war.

There were many changes that took place within the course of World War I following the Russian Revolution. One major change that this had on the war was that Russia and Germany settled their conflict.

The majority of the population of the Balkans and Russia are the Slavs. So, they shared that, and they felt closer to Russia.

Kaiser Wilhelm's grandmother was Queen Victoria of England.

Not at first, but Serbia was occupied by the Central Powers at the end of 1915.

In world war 1 the central powers were Germany, Austria-Hungary and the Ottoman empire. Italy was part of that alliance but because it switched sides before the name changed from the triple alliance to the central powers it is generally not considered a central power. The allied powers were the British empire, France, Russia and later the United states.

Kaiser Wilhelm the II died because of Pulmonary embolism at age of 82, in the Netherlands.

The triple alliance was between Germany, Austria- Hungary, and Italy. Be care ful not to mix it up with the Triple Entente which was between Britain, France and Russia.

You need to narrow down this question a bit. WW1 took place 1914 - 1918, not 1913-1933.

Theobald von Bethmann-Hollweg was the German Chancellor during the first few years of World War 1. After his death a plan was found called Septemberprogramm which outlined Germany's various expansionist goals it hoped to achieve from victory in World War 1. Since its finding, it has often been referenced as Germany's true motivations for war.

Germany was forbidden to unite with Austria in the treaty of Versailles.

It was the spark that began World War 1.

The tank.

Not very. The Royal Navy (of the United Kingdom) had managed to achieve a blockade of Germany and was effectively starving the nation of all resources it could only achieve through importing. France, Britain, and Italy were worn down and hadn't made any geographical progress, but Germany had less manpower and industrial capacity combined. The fuel shortage and harsh winters of 1917 made a severe impact on both sides on the home front, many civilians were killed simply due to being unable to warm themselves. However, with the American declaration it had pretty much sealed victory against Germany and Austria-Hungary. Their conspiracy with Mexico had achieved the worst possible results, Mexico didn't declare war and join the German Alliance but the negotiations had been uncovered with the decoding of the Zimmerman Telegram. Instead of creating a war between Mexico and the US, it had only brought another enemy against them. This only gave the Kaiser the view that the Great War was inevitably lost, with his abdication lesser German politicians were forced forward to assume command and pushed for the peace deal known as the Treaty of Versailles. The Great War wasn't ended because one side militarily collapsed or was defeated, but the idea (rightly or wrongly) that the war could only be lost was strengthened by a number of factors, America joining the war against them being one of the many. A rapidly degrading economic sitation could be seen to be far more dire for the German war effort.

The Allies, which are America, Great Britain, France, and more, won World War I.
