Pal t`Sa'ovaya - refers to the era before Surak
The Vulcan historians' name for the period has always been Age of Expansion. Only much later did it begin to be referred to as the "pre-Reformation" or "pre-Awakening" period. It was the time in which many of the petty kingdoms of the old world had been unified - mostly against their will. This process had, of course, been going on for a long time.
There are historians who will point out that from the tome of Earth's Bronze age, around 10,000 BCE, and the fall of the Spartans at Thermopylae, there was only one period of ten standard years during which as much as ten percent of Vulcan was not at some kind of war, economic or political. But in the Age of Expansion the process of "unification" sped up considerably.
