The First Piala War was fought between the Alliance and the Covenant (with help from the Axis), primarily over control of Forerunner technology. The war clearly demonstrated the failure of the Covenant's attempts to modernize its military and fend off threats to its sovereignty, especially compared with Alliance's successful restoration[1] This was the mark where the Covenant and UNSC formed into the United Alliances of Orion Species. Within Covenant Empire remnants, the defeat (along with the betrayal the Axis did) was a catalyst for joining the Coalition of Independent States.
