great enemies of the tribe were the bands of the Blackfoot
confederacy which alternately retreated and advanced on
the western front according to the fortunes of battle.
The Cree names for the Blackfoot tribes were pikano-wiyiniwak,
Piegan, kaskitewiyasitak, literally, Black Feet, mihkowiyiniwak,
Blood People. The Sarsi, sas-iwak, also made many forays
To the south and southwest were several hostile peoples.
The Dakota, pwatak, were always dangerous. The Crow, kahkakzwaltcanak,
Crow Foot, were noted as a tribe from whom it was particularly
difficult to steal horses. The pawistikowiyiniwak Rapids
People, Gros Ventre, were occasionally encountered. The
village tribes of the Missouri were called kotasiskikamikowak,
Mud House People, and were sometimes raided. Tribes rarely
met, but none the less known as enemies, were the Cheyenne,
kanehiaw estcik, Cree Speakers (from the fact that the
Cree could recognize some of the Cheyenne words), kinepiko-
wiyiniwak, Snake, palpe-komak, Nez Perce, and napakstokwewak,
Flathead. All hostile peoples were included in the generic
term, ayahtclyiniwak. Since the Blackfoot in particular
were the enemy tribe, this term came to be especially
applied to them.
