Royal heirs and princes expected to succeed to a throne occupied an unusually precarious position: close enough to power to govern, command armies, or shape policy, but not yet secure in possession of it. Illness, warfare, assassination, execution, and dynastic rivalry could abruptly redirect succession. These twelve princes are significant because each had already exercised political, military, intellectual, or administrative influence before his path to supreme rule was cut short.
- Liu Ju, Prince Wei (128–91 BCE) – Western Han China – heir to Emperor Wu, Liu Ju governed during his father's absences but was driven into rebellion during a court conspiracy and died by suicide after defeat. His death disrupted the succession and contributed to a period of uncertainty at the Han court.
- Germanicus Caesar (15 BCE–19 CE) – Roman Empire – celebrated for his campaigns in Germania and enormously popular with the army and public, Germanicus died unexpectedly in Syria amid accusations of poisoning, leaving the imperial succession to develop along a very different path.
- Crispus (c. 300–326 CE) – Roman Empire – Constantine I's eldest son was an accomplished commander who governed Gaul and helped secure his father's position before being executed on Constantine's orders under circumstances that remain obscure.
- Li Xian, Prince Zhanghuai (655–684) – Tang China – an accomplished scholar and crown prince who exercised authority during Emperor Gaozong's illness, Li Xian was removed after accusations of treason associated with Empress Wu Zetian and later forced to commit suicide.
- William Adelin (1103–1120) – England – Henry I's only legitimate son and recognized heir drowned in the White Ship disaster. His death left no secure male successor and helped precipitate the prolonged civil conflict known as the Anarchy.
- Edward, the Black Prince (1330–1376) – England – heir to Edward III and one of the most celebrated commanders of the Hundred Years' War, Edward died after years of illness before becoming king; the crown eventually passed to his young son, Richard II.
- Şehzade Mustafa (1515–1553) – Ottoman Empire – a popular and experienced son of Suleiman the Magnificent, Mustafa was regarded as a strong contender for succession but was executed on his father's orders amid accusations of treason and intense court rivalry.
- Dara Shikoh (1615–1659) – Mughal Empire – Shah Jahan's favored heir was a scholar and advocate of intellectual exchange between Islamic and Hindu traditions. Defeated by his brother Aurangzeb in the Mughal succession war, he was captured and executed.
- Abbas Mirza (1789–1833) – Qajar Iran – crown prince, military commander, and reformer who sought to modernize Iran's army and administration. He died shortly before his father, leaving his reform program incomplete amid increasing European pressure.
- Crown Prince Kanaung (1819–1866) – Konbaung Burma – a major advocate of industrial and military modernization who developed arsenals and sought foreign expertise. His assassination during a palace rebellion deprived Burma of one of its leading reformers.
- Archduke Franz Ferdinand (1863–1914) – Austria-Hungary – heir presumptive to the Habsburg monarchy and advocate of restructuring the empire, he was assassinated at Sarajevo on 28 June 1914. The resulting diplomatic crisis became the immediate trigger for the First World War.
- Prince Louis Rwagasore (1932–1961) – Burundi – nationalist leader, royal prince, and newly appointed prime minister who helped lead Burundi toward independence. His assassination months before independence deprived the emerging state of one of its most important political leaders.
The loss of an heir could change far more than the identity of the next ruler. It could reorder dynastic alliances, trigger civil war, interrupt reform, alter foreign policy, or elevate political figures who otherwise might never have ruled. These cases therefore provide a particularly useful way to study historical contingency: not by speculating about what each prince would have done, but by examining what demonstrably changed once he was removed from the succession.
