How much of a historical historical aberration is 19th century Mexico’s scalphunting model of suppressing rebellions?
A few years ago, I did some research about the Native American conflicts on the Mexican American border, the inspiration behind Cormac McCarthy's Blood Meridian. From what I’ve read, the Apaches and Comanches mercilessly raided much of northern and central Mexico during the early and mid 19th century. They were mostly unimpeded, as the Comanches and Apaches outmatched the skeletal Mexican army. In their attacks, they killed thousands of peasants, abducted hundreds of others, displaced thousands of the remaining survivors, and stole tens of thousands of livestock.
Apaches and Comanches war bands were even bold enough to assault capital cities like Chihuahua in broad daylight. It got to the point that the Comanche and Apache raids left much of the border regions depopulated. As the Mexican army was in shambles, the government turned to loose gangs of bounty hunters and mercenaries to quell the depredations.
The bounty hunters and mercenaries were a motley and diverse bunch. Their ranks mostly consisted of Anglo-American settlers, displaced Woodland Native Americans from what is now the Eastern Coast states (such as the Seminoles, Shawnee, and Delaware), traditional enemies of the Apaches (such as the Pimas and the Tarahumara), and a few escaped slaves. Mexican officials commissioned them to kill and scalp any Apaches they could get their hands on. Including women and children, who had bounties of $50 and $25 US silver dollars per scalp respectively.
In retaliation to the Mexican government sanctioned genocide against them, the Apaches escalated their raids to the point of wiping out entire small towns and table turned would be scalp hunters left and right. Many scalp hunters decided that it was safer to prey upon peaceful Native American bands and Mexican peasants (ironically the very people they were hired to protect in the first place) and pass them off as Apache scalps rather than going after the Apaches themselves.
With the crippling financial costs and incessant cheating and backstabbing, the Mexican government abandoned the scalp hunting program. Though due to decentralization and lack of communication, some states were slower to drop the scalp hunters than others. Comanche and Apache raids still continued on until the 1870s and 1890s respectively. The Comanche raids into Mexico were only ended by the Americans forcing them into reservations.
In the later half of the 19th century, the Apaches virtually fought a two-front war against the Americans in the North and the Mexicans to the South, until pressure from both countries overwhelmed them. Although most of the major Apache bands surrendered to American and Mexican forces in the 1880s and 90s, some isolated individuals held out until as late as the 1910s-30s.
As a quick question, how much of a historical aberration is Mexico’s scalphunting program against the Apaches? Have there been other instances of states that used similar bounty hunting models as their primary means of suppressing rebellions? If so, what are other similar examples of this phenomenon happening?
