When the Pequot chief Sassacus began his war with the English, chief Uncas allied himself with Sassacus. In the meantime, Uncas had a worthwhile trade with the English, and wanted no war with these people. Therefore Uncas and his allies deserted the Pequot and founded the Mohegan branch. These two branches thenceforward faced each other with continuing hostility. In the following war Uncas advanced [re-invented?] himself as a true ally of the English, and was a great force toward the destruction of his erstwhile people. But Sassacus and some other Pequots managed to flee from the massacre. He went with his followers back to the Mohicans, with whom he hoped to hide. However, the Mohicans, in the meantime, had become subject to the Mohawks, who had conquered them. The Mohawks beheaded Sassacus and sent his head to Haftford as proof of their loyalty.
They exist today under the name Mohegan. Under their chief Ralph W. Sturges the tribe gain federal recognization and won the right to build and operate a casino and hotel on their reservation in Uncasville, Connecticut. There have also been projects to record as much as the Mohegan language as possible from the tribe\'s elders and record it on CD-ROM to teach to younger generations.
