Who married María de Hohenzollern-Sigmaringen?

María de Hohenzollern-Sigmaringen (en alemán, Marie von Hohenzollern-Sigmaringen; Sigmaringen, 17 de noviembre de 1845-Bruselas, 26 de noviembre de 1912) fue una princesa de Hohenzollern-Sigmaringen con el tratamiento de Alteza Serenísima, que contrajo matrimonio con el príncipe Felipe de Bélgica, conde de Flandes, y fue madre del rey Alberto I de Bélgica.

Prince Philippe of Belgium, Count of Flanders (Dutch: Filips; 24 March 1837 – 17 November 1905), was the third born and second surviving son of King Leopold I of Belgium and Louise d'Orléans. He was the brother of Leopold II of Belgium and Empress Carlota of Mexico.

Born at the Château de Laeken, near Brussels, Belgium, Philippe was created Count of Flanders on 14 December 1840. In January 1869, upon the sudden death of his nephew Prince Leopold, Duke of Brabant, he became heir presumptive to the Belgian throne. In 1866, after the abdication of Alexandru Ioan Cuza, Prince of Romania, Philippe refused being named the new Romanian sovereign, and the throne was later accepted by Philippe's brother-in-law Carol I. Earlier, he had also refused the crown of Greece, which was offered to him in 1862.

Philippe died in 1905. When his brother King Leopold II died in 1909, Philippe's second son ascended the Belgian throne as King Albert I.
