No, No, No, No, Alan! There is no such record of this for 99% of our evolutionary history. Your have baked your premise into your evidence! We have no clue about our social organisation for about 98% of our evolutionary history. Before say 2,000 BC we don’t know their organization. Other than that they lived in smallish villages in Neolithic times (without obvious palaces or castles of kings).

Before that there’s evidence they lived in smaller nomadic or cave dwelling groups, but I can’t think of a single bit of evidence for a single alpha male being key to their social structure.

If we look to our primate cousins, we see a huge variety - chimps have complex societies which have alpha males and alpha females, but these depend on coalitions of power among many individuals.

Bonobos, very chimp like in appearance, have matriarchal leaders.

Gorillas have single family groups with a dominant male for each “harem”

Orangutans are solitary; only mothers and their offspring form a social bond.

Gibbons are also solitary except that they pair bond for life.

Personally, I see all of these options present in different social groups.
