In case of what country's attack was the origins of the Central Powers?
Central Powers The Central Powers (German: "Mittelmächte" ; Hungarian: "Központi hatalmak" ; Turkish: "İttifak Devletleri" or "Bağlaşma Devletleri" ; Bulgarian: Централни сили "Tsentralni sili" ), consisting of Germany, Austria-Hungary , the Ottoman Empire and Bulgaria – hence also known as the Quadruple Alliance (German: "Vierbund" ) – was one of the two main factions during World War I (1914–18). It faced and was defeated by the Allied Powers that had formed around the Triple Entente. The Powers' origin was the alliance of Germany and Austria-Hungary in 1879. The Ottoman Empire and Bulgaria did not join until after World War I had begun, although the Ottoman Empire retained close relations with both Germany and Austria-Hungary since the beginning of the 20th century.
Spirit of 1914 The Spirit of 1914 (German: Augusterlebnis) was the alleged jubilation in Germany at the outbreak of World War I. Many individuals remembered that euphoria erupted on 4 August 1914 after all the political parties in the Reichstag, including the previously antimilitarist Social Democratic Party of Germany (SPD), supported the war credits in a unanimous vote, later referred to as the "Burgfrieden" (literally "castle peace", but more accurately party truce). Many, particularly those in the middle class, believed Germany had ended its decades of bitter domestic political conflict. The string of military victories in the following weeks, which demonstrated what Germany could accomplish when unified and suggested that the war would be short, reinforced the ebullience. Many on the political right accordingly believed, and continued to believe into the Nazi era, that these first weeks of the war were Germany's finest hour, the German equivalent to 1789 in France. Until the 1990s, most historians took the memory of the Spirit of 1914 at face value and claimed that the enthusiasm in August 1914 was universal.
