Which conflict was known as the bloodless Aroostook War?

The conflict known as the bloodless Aroostook War was primarily a dispute over territory between the United States and Great Britain regarding the boundaries between Maine and New Brunswick. This confrontation began in the late 1830s and was characterized by a series of skirmishes and tensions between American and British lumberjacks in the disputed area, particularly around the Aroostook River region.

Despite the term "war," there were no significant battles or casualties, which is why it is referred to as a "bloodless" conflict. The tensions were eventually resolved through diplomacy, culminating in the Webster-Ashburton Treaty of 1842. This treaty established the boundary between the U.S. and British territories in the region, thereby settling the issue without escalating into full-scale violence.

The other options relate to different conflicts or contexts: skirmishes in Canada involve broader territorial disputes but are not specifically tied to the Aroostook issue; the border conflict with Mexico refers to subsequent conflicts such as the Mexican-American War; and the uprising against British rule does not apply, as the Aroostook War was not a revolution or rebellion but rather a territorial dispute.
