Powder keg
barrel of gunpowder
A powder keg is a barrel of gunpowder. The powder keg was the primary method for storing and transporting large quantities of black powder until the 1870s and the adoption of the modern cased cartridge. The barrels had to be handled with care, since a spark or other source of heat could cause the contents to deflagrate.
In practical use, powder kegs were small casks to limit damage from accidental explosions. Today they are valued as collectibles. Specimens of early American kegs for gunpowder are found in sizes like 8+3⁄4 inches (22 cm) tall by 6+1⁄2 inches (17 cm) diameter and 13 inches (33 cm) tall by 11 inches (28 cm) diameter, often with strappings of reed or sapling wood rather than metal bands to avoid sparks. Kegs for blasting powder used for mining or quarrying were often larger than kegs for shipping and storing powder for firearms.
As a metaphor
A powder keg is also a metaphor for a region that political, socioeconomic, historical or other circumstances have made prone to outbursts. The analogy is drawn from a perception that certain territories may seem peaceful and dormant until another event triggers a large outburst of violence. The term is most often used to simplify and help the understanding of what is often a complex set of circumstances that lead to conflicts, such as the powder keg of Europe.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 30, 2025. The linked authority identifier is Q7236013. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
