Where is Satan's throne located according to Revelation?

Revelation 2:12&13 "And to the angel of the church in Pergamum write: The One who has the sharp two-edged sWord says this: 'I know where you dwell, where Satan's throne is."

This verse indicates that it is in Pergamum.

Answer:

Satan is enthroned upon and rules within all the governments of man on earth:

"...the Devil...sheweth Him ALL THE KINGDOMS OF THE WORLD... and saith unto Him, All these things will I give thee, if thou wilt fall down and worship me." (Matt.4:8-9)

It's the presidents, kings, premiers, etc., of the governments of man whom Satan, the coming Beast and the False Prophet will call upon to fight Christ as He approaches earth with His army:

"...I saw three unclean spirits like frogs come out of the mouth of the Dragon [Satan - Rev.12:9], and out of the mouth of the Beast, and out of the mouth of the False Prophet. For they are the spirits of devils [demons], working miracles, which go forth unto the KINGS OF THE EARTH and of the WHOLE WORLD, to gather them to the battle of that Great Day of God Almighty... and they [should be THEY, the three demons] gathered them together into... Armageddon." (Rev.16:13-16)
