Pillage

Looting, also referred to as sacking, ransacking, plundering, despoiling, despoliation, and pillaging, is the indiscriminate taking of goods by force as part of a military or political victory, or during a catastrophe, such as war,natural disaster, or rioting. The term is also used in a broader sense to describe egregious instances of theft and embezzlement, such as the "plundering" of private or public assets by governments. Looting is loosely distinguished from scavenging in terms of objects taken: scavenging implies taking of essential items such as food, water, shelter, or other material needed for survival while looting implies items not necessary for survival such as luxury goods, art work, precious metals or other assorted items of value to the looters. The proceeds of all these activities can be described as booty, loot, plunder, spoils, or pillage.

Looting by a victorious army during war has been common practice throughout recorded history. For foot soldiers, it was viewed as a way to supplement their often meagre income and was part of the celebration of victory. On higher levels, the proud exhibition of loot was an integral part of the typical Roman triumph, and Genghis Khan was not unusual in proclaiming that the greatest happiness was "to vanquish your enemies... to rob them of their wealth..."

In warfare in ancient times, the spoils of war included the defeated populations, which were often enslaved, and the women and children, who were often absorbed into the victorious country's population. In other pre-modern societies, objects made of precious metals were the preferred target of war looting, largely because of their easy portability. In many cases looting was an opportunity to obtain treasures that otherwise would not have been obtainable. Since the 18th century, works of art have increasingly become a popular target. In the 1930s and even more so during World War II, Nazi Germany engaged in large scale and organized looting of art and property.
