List of usurpers

The following is a list of usurpers – illegitimate or controversial claimants to the throne in a monarchy. The word usurper is a derogatory term, and as such not easily definable, as the person seizing power normally will try to legitimise his position, while denigrating that of his predecessor.

Belgium

Usurper	Predecessor	Reign	Comments
Leopold I of Belgium	William I of the Netherlands	1831–1865	The southern provinces of the Netherlands declared independence from the United Kingdom of the Netherlands with Leopold I being proclaimed King and sovereign ruler of the newly established Kingdom of Belgium in 1831. King William I of the Netherlands refused to accept the illegal separation of Belgium and launched the Ten Days' Campaign, a large military offensive by the Dutch to recapture the renegade southern provinces. Although initially successful for the Dutch, the French however backed the Belgians militarily and thereby forced the Dutch to accept diplomatic mediation. In 1839, the two countries signed the Treaty of London, officially recognizing the Kingdom of Belgium as an independent and sovereign state, and Leopold I as its legitimate ruler.

Usurper	Predecessor	Reign	Comments
William I	Harold Godwinson	1066–1087	When Edward the Confessor died, Harold crowned himself Harold II; William then invaded England with his own army. William's army was victorious at the Battle of Hastings, during which Harold II was killed. William then crowned himself King of England.
Stephen	Henry I	1135–1154	Henry I named his daughter Matilda his heir, and she was recognised as such by the barons of England. On Henry's death, Stephen took the crown before Matilda learned that her father was dead, which led to 20 years of civil war.
Henry IV	Richard II	1399–1413	A period of crisis emerged in 1398–1399 under Richard II as he enacted revenge on leading nobles for a dispute ten years previously. He took action against the Lords Appellant, murdering a leader and banishing Henry Bolingbrooke. On the death of Bolingbrooke's father, John of Gaunt, the son wished to return to claim his inheritance as the Duke of Lancaster, which Richard II denied. Henry returned from his exile in France whilst Richard II was away in Ireland. With the support of prominent Northern noble families, Henry took the throne.
Edward IV	Henry VI	1461–1470 1471–1483	After the death of his father, Richard of York at the Battle of Wakefield in 1460, Edward took over leadership of the Yorkist faction. His father had been declared the king's heir by parliament, but Edward took the further step of proclaiming himself king in March 1461. He subsequently defeated Lancastrian forces at the Battle of Towton, forcing Henry VI into exile in Scotland.
Richard III	Edward V	1483–1485	When his brother King Edward IV died in April 1483, Richard was named Lord Protector of the realm for Edward's eldest son and successor, the 12-year-old Edward V. Arrangements were made for Edward's coronation on 22 June 1483; but, before the young king could be crowned, the marriage of his parents was declared bigamous and therefore invalid, making their children officially illegitimate and thus barring them from inheriting the throne. On 25 June, an assembly of Lords and commoners endorsed a declaration to this effect and proclaimed Richard the rightful king.
Henry VII	Richard III	1485–1509	Forces under Henry Tudor won the Battle of Bosworth Field, during which Richard III was killed. Henry then became Henry VII and married the daughter of Edward IV, which is claimed to have ended the War of the Roses, though relatives of Richard made various attempts to remove him from power.

Later on, both sons Mohammad Ali Khan and Abol-Fath Khan Zand were declared co-shahs, but they were only puppet rulers with nominal power; the real power was taken into the hands of their uncle Zaki Khan who was the de facto ruler. However, his reign was short-lived being murdered by rebellious tribal leaders after a few months.
Sadeq Khan Zand	Abol-Fath Khan Zand	1779–1781	With Zaki Khan Zand being killed in June 1779 and Mohammad Ali Khan Zand died of a heart attack in the same month, Abol-Fath Khan Zand was proclaimed the sole official (3rd) Shah of the Zand dynasty by his uncle Sadeq Khan Zand.
