The Fourth World War, alternatively known as WWIV or World War IV, was a military conflict spanning from July 28, 1907 to August 8, 1913. Two alliances, the Entente (centered on the Triple Entente) and the Alliance of Steel (centered on the Triple Alliance), composed of a vast majority of the world's nations, including the major powers of the time (America, Russia, Germany, France, Austria, England, and Scandinavia), engaged in a massive total war that saw the first use of several new and more lethal weapons than seen before, including the first implementations of the tank and airplanes. It created itself into the most devastating war in history up until that time, only to be surpassed by the Fifth World War. The war is generally accepted to have been started with the assassination of English Prime Minister H. H. Asquith and the subsequent declaration of war on Scotland from England. The global system of alliances led to nearly all of the world's nations participating, with the notable exceptions of the three nations of the so-called Muslim Bloc of the Maghreb, Arabia, and India.
Starting on 28 July, English troops began to move north across the Scottish border, advancing a few miles before being halted by the Scottish defense. France declared support for Scotland on 1 August, after which Germany demanded that France not intervene lest Germany itself get involved on England's side. France ultimately began giving supplies to Scotland, resulting in the German invasion of the Rhineland and later other eastern French lands. Russia declared war on Germany in the name of the Triple Entente, prompting Austria to declare war on Russia. The war between Germany and Russia also caused skirmishes in Africa, which Ethiopia intervened in on the Allied side. China also declared war on Russia with the intent of regaining land lost in previous wars. Japan, bound by the Russo-Japanese Pact of 1902, was obliged to declare war on China, and as a result, engulfed the entire Asian continent into the war. The war merged with the outside Second South American War when Brazil and Argentina declared on the French Dominion of Patagonia. Patagonia, already involved in the war in Europe, sought aid from the United States. Theodore Roosevelt urged Congress to declare war on the Allied Powers, but was rejected twice until Mexique, sending supplies and troops to England, attempted to exploit American infighting by invading border lands. Roosevelt achieved his declaration of war in early 1909, igniting total war in the Western Hemisphere.
The end of the war resulted in the dismantling of the Austrian Empire to Austria proper, as well as massive monetary reparations forced upon the defeated Alliance.

Exit of Spain and beginning of the end
Spain, always suffering internal strife, began to suffer peasant uprisings in 1912. The war had caused widespread starvation and an increase in poverty. Furthermore, Portuguese nationalists began to seek independence from Spain again. After the Toledo Incident, the Spanish Civil War began, with the existing Bonaparte monarchy fighting the Portuguese, Muslims in the south, and the lower class. Spain officially exited the war in November 1912, signing peace treaties with England and Germany. The war would last beyond the end of the war, but the Bonaparte family was held under arrest by Francisco Franco. They were freed by French agents after the war, but the civil war continued nonetheless.
At the same time as the start of the Spanish Civil War, France pushed Germany entirely out of its lands. Russia had made great gains Austria, and Japan was occupying Northern China. In England, popular support for the war was dying out, and Oswald Mosley, returned from the front in Scotland after an injury, began rallying pacifists and poor people alike to his fascist cause, while King George attempted to pressure Parliament into ending the war. However, Parliament believed that seeking peace would be a humiliating action and continued on.
In Germany, riots were breaking out in southern territories like Bavaria. Much of the retreating army was forced to focus on quelling internal problems. Meanwhile in Austria, Slavic peoples were idly standing by and welcoming the Russians as brothers and liberators. The number of men in the armed forces was nearly halved between the start of 1912 and that of 1913. Deserters became extremely common, with most of them being from oppressed Slavic families or enlisted soldiers.
The United States was making rapid advances into Mexique and was focusing on naval assaults on Brazil, Peru, and Argentina. Patagonia was receiving aid from South Africa.
