omniarch

noun

1. A ruler of the world or everything.

   “I was a man born to a field estate:/Abaddon was my brother, and he grew/To his vast prime, an omniarch, elate/With knowledges of power, and, ere the dew/Of youthful mom fled his pellucid eyes,/His soul had cleft the vaulted centuries.”

   “These are all to be federated , and finally to embrace the whole world under a supreme magistrate or "omniarch, residing in Constantinople. Fourier's system prefers agriculture to other branches of work, and particularly affects arboriculture and horticulture. It also favours agriculture on a large scale, and provides for a comparative falling off in manufactures through the abatement of luxury.”

   “Enfantin, the leader of the Saint-Simonians, bore the title of Father. In Fourier's scheme it was expressly declared that there were to be rulers or unarchs; and the supreme ruler, who was to reside in Constantinople, would be known as the omniarch.”
