(1) Franz Ferdinand, Archduke of Austria-Este (1863–1914) was an Archduke of Austria, Prince Imperial of Austria, Prince Royal of Hungary and Bohemia, and from 1896 until his death, heir presumptive to the Austro-Hungarian throne. His assassination in Sarajevo precipitated the Austrian declaration of war which triggered World War I.
Franz Ferdinand was born in Graz. In 1877 he entered the army with the rank of third lieutenant. In 1889, Franz Ferdinand's life changed dramatically. His cousin Crown Prince Rudolf committed suicide, leaving Franz Ferdinand's father, Archduke Karl Ludwig, as first in line to the throne. In 1900, Franz married Countess Sophie Chotek.
On June 28, 1914, Franz Ferdinand and his wife were killed in Sarajevo by Gavrilo Princip, a member of Young Bosnia. The event, known as the Assassination in Sarajevo, was one cause of World War I.

(2) Karl of Austria (1887-1922), more formally known as Karl Franz Josef Ludwig Hubert Georg Maria von Habsburg-Lothringen, was the last Emperor of Austria, the last King of Hungary, and the last monarch of the Habsburg Dynasty. He reigned as Emperor Karl I of Austria and King Karoly IV of Hungary from 1916 until 1918, when he renounced the government (but did not abdicate). Karl was the son of Otto Franz of Austria (1865-1906), younger brother of Archduke Franz Ferdinand, whose assassination triggered World War I. In 1911 he was married to Princess Zita of Bourbon-Parma.
His reign began in 1916. In 1917, Karl secretly sued for a separate peace with France, deserting his German ally. When news of the overture leaked, he denied all involvement, until the French published letters signed by him.
He fled to Switzerland after the empire collapsed at the end of the war, but refused to abdicate. Encouraged by Hungarian nationalists, he sought twice in the early 1920s to reclaim the throne of Hungary, but failed, due to various factors including the betrayal of the Hungarian Regent M. Horthy, whom Karl had helped to appoint. He died on the island of Madeira in 1922.

(3) Zita of Bourbon-Parma, Princess of Parma(1892-1989) was the last Empress-consort of Austria and Queen-consort of Hungary. She was a daughter of the deposed Robert I, Duke of Parma and his second wife. Zita married Karl of Austria in 1911. She was accused by critics of being behind her exiled husband's attempts to regain the throne of Hungary from which he had not abdicated.
After Karl's death in 1922, Zita left Madeira but continued living abroad and kept in contact with many of Europe's royal houses throughout her exile.She died in Switzerland. In 1982, the Austrian government granted Zita the right to re-enter Austria, although she had never renounced the Habsburg claim to the throne. She was buried in Vienna's Imperial Crypt which had served for centuries as the Habsburg family's burial place.
