Circle the wagons is an English language idiom which may refer to a group of people uniting for a common purpose.
At night the wagons would form a circle around their encampment and livestock for defensive reasons.
[1][2] "Circling the wagon" is still an idiomatic expression for a person or group preparing to defend themselves against attack or criticism.
[8] Some Indigenous people view the term as offensive based on its literal meaning stemming from the manifest destiny era.
[9] Some critique the term on the basis that it is culturally insensitive and evokes racist images of Native Americans.
