The Holy Ydoran Empire, also known as Holy Empire Yudora, existed in Ivalice 1,200 years prior to the plot of Final Fantasy Tactics. Saint Ajora Glabados was secretly working against them until Germonique reported him to the authorities. Ajora was executed, but a large wave destroyed the place of power of Pharism, which was then the dominant religion, resulting in the rise of the Church of Glabados.

According to Jenomis cen Lexentale, on the Source the Holy Ydoran Empire ruled Ivalice several centuries before the time of the War of the Lions. As the empire grew so too did its ruling class grow corrupt, and they seized the wealth of the land until the common folk could take it no more.
