Prince Sixtus of Bourbon-Parma attempted came from which of the two countries that made up The Powers' alliance in 1879?
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.
Kingdom of Lombardy–Venetia The Kingdom of Lombardy–Venetia (Italian: "Regno Lombardo-Veneto" , German: "Königreich Lombardo–Venetien" ; Latin: "Regnum Langobardiae et Venetiae" ), commonly called the Lombardo-Venetian Kingdom, was a constituent land (crown land) of the Austrian Empire. It was created in 1815 by resolution of the Congress of Vienna in recognition of the Austrian House of Habsburg-Lorraine's rights to Lombardy and the former Republic of Venice after the Napoleonic Kingdom of Italy, proclaimed in 1805, had collapsed. It was finally dissolved in 1866 when its remaining territory fell to the Kingdom of Italy.
