A punitive expedition is a military journey undertaken to punish a state or any group of persons outside the borders of the punishing state. It is usually undertaken in response to perceived disobedient or morally wrong behavior, but may also be a covered[vague] revenge. More commonly in the 19th century, punitive expeditions were used as pretexts to colonial adventures that resulted in annexations, regime changes or changes in policies of the affected state to favour one or more colonial powers.
Stowell (1921) provides the following definition:
"When the territorial sovereign is too weak or is unwilling to enforce respect for international law, a state which is wronged may find it necessary to invade the territory and to chastise the individuals who violate its rights and threaten its security".
Notable punitive expeditions 
- In the 13th century Kublai Khan, the founder of the Yuan Dynasty, sent emissaries demanding tribute from the Singhasari kingdom of Java. The ruler of the Singhasari kingdom, Kertanagara, refused to pay tribute and tattooed a Chinese messenger, Meng Qi, on his face. A punitive expedition sent by Kublai Khan arrived off the coast of Java in 1293. Jayakatwang, a rebel from Kediri, had killed Kertanagara by that time. The Mongols allied with Raden Wijaya of Majapahit against Jayakatwang and, once the Singhasari kingdom was destroyed, Wijaya turned against the Mongols and forced them to withdraw in confusion.
- In 1599 the Spanish conquistador Juan de Oñate ordered his nephew Vincente de Zaldivar to engage in a punitive expedition against the Keres natives of Acoma Pueblo. When the Spanish arrived, they fought a three-day battle with the Keres leaving about 800 men, women and children dead.
- During the First Anglo-Powhatan War (1610–1614), Thomas West, 3rd Baron De La Warr (1577–1618), an English nobleman was appointed Virginia's first royal governor and ordered to defend the colony against the Powhatan. Lord de la Warr waged a punitive campaign to subdue the Powhatan after they had killed the colony’s council president, John Ratcliffe. His tactics against the Indians proved effective and included raiding their villages, burning their homes, torching their cornfields and crops, and plundering their provisions.
