List of shortest-reigning monarchs

A monarch is the leader of a monarchy, a position usually intended to last for life or until abdication or deposition. The reigns of some monarchs have been notably short. Many of these monarchs acceded to the throne as a result of being first in an order of succession, while other monarchs claimed the throne as a result of conflict. The authenticity of some monarchs has been disputed, especially those who reigned during conflict. One factor in such debates is whether the monarch held the throne in a symbolic or nominal capacity.

Monarchs who reigned for less than a day

Portrait	Monarch	Reign	Length	Notes	Ref.
	Louis XIX King of France	2 August 1830	About 20 minutes (disputed)	Heir-apparent of Charles X, who was forced to abdicate during the July Revolution. His abdication and his father's were announced through the same document, which refers to him as dauphin only. Louis Antoine is said to have been king between his father's signature and his own, but this does not appear to be historically accurate.
	Luís II King of Portugal	1 February 1908	About 20 minutes (disputed)	Carlos I was murdered in the Lisbon Regicide; his heir-apparent Prince Luís Filipe was also fatally wounded in the attack. Because Luís Filipe survived his father by about 20 minutes, the Guinness Book of Records identifies him as the second-shortest reigning monarch. However, according to the Portuguese tradition, the new monarch must be proclaimed by the Cortes Gerais; thus, the reign of Luís Filipe is disputed and not officially recognised. His younger brother, Manuel, who survived the attack, became the new king following his acclamation in the Cortes.
	Daughter of Xiaoming Emperor of Northern Wei	1 April 528	Less than a day	Proclaimed "Emperor" as an infant by her grandmother, Empress Dowager Hu, who passed her off as male. Later that same day, Hu admitted she was actually female and proclaimed Yuan Zhao as emperor. Official historical records never listed her as a legitimate sovereign.
	Philip Antipope	31 July 768	Less than a day	Elected after the death of Pope Paul I. His election was declared invalid, and he was declared guilty of simony; having been stripped of the pontifical garments, he was then personally forced to return to his monastery.
	Wanyan Chenglin Emperor of Jin	9 February 1234	Less than a day	Emperor Aizong abdicated in his favor while they were still besieged by the Mongols at Caizhou, then committed suicide by hanging. Killed while leading a charge in the streets of Caizhou
	Celestine II Antipope	13/14 December 1124	Less than a day	Elected after the death of Pope Callixtus II. Abdicated a couple of hours into his papacy due to factional violence breaking out during the investment ceremony
	Michael II Emperor of Russia	15 March 1917	Less than a day (disputed)	Succeeded after the abdication of Nicholas II. Made his accession conditional on the decision of the Provisional Government, contrary to the wishes of Nicholas, who abdicated without informing either. Numerous questions surround the existence of any "reign", starting with the legality, or lack thereof, of Nicholas's abdication to his brother while bypassing his son Alexei.
	Min Shin Saw King of Burma	1167	Less than a day	Succeeded after the death of his father Sithu I, who was smothered by his younger son Narathu. Min Shin Saw was assassinated that same night on his brother's order.

	Michael Emperor of Trebizond (first reign)	30 July 1341	Less than a day	Acclaimed emperor after arriving with the intention to marry Irene Palaiologina, who had been overthrown by Anna Anachoutlou while the voyage was underway. He was deposed and imprisoned on that same night by Anna. He recovered the throne in 1344 and reigned for five years.
	Soththisena King of Anuradhapura (Sinhala Kingdom)	434	Less than a day	He succeeded his father Mahanama as king and was succeeded by his stepsister, Chattagahaka Jantu. According to the Lesser Chronicle (Cūḷavaṃsa) of Sri Lanka, King Soththisena, the shortest reigning king of Sri Lanka, ascended the throne in the morning and was assassinated that evening in a palace conspiracy.

	Napoleon II Emperor of the French	4–6 April 1814 (first reign)	2 days (disputed)	His father Napoleon Bonaparte was declared deposed by the French senate on 4 April 1814, but his formal abdication was not proclaimed until two days later.

	Stephen (II) Pope	22 (or 23) – 25 (or 26) March 752	3 days (disputed)	Elected after the death of Pope Zachary. Died of a stroke.

Because of this, he was removed from the official List of popes in 1961, and Pope Stephen III was redesignated as Pope Stephen II.
