Sardis was taken by the Persians (see Ancient Empires - Persia) about 546 B.C., and then later in turn by the Athenians, Seleucids and the Attalids. When the Romans (see Ancient Empires - Rome) took it in 133 B.C., it became the capital of the Roman province of Lydia. The city was severely damaged by an earthquake (see Earthquake!) in 17 A.D., and although the Romans reportedly spent 10,000,000 sesterces for damage repair, the city never fully recovered its former glory.
Sardis was located in the Hermus Valley, near the major road system that linked it with Ephesus, Smyrna, Pergamum, Thyatira, Philadelphia, Laodicea - where The Seven Churches of Revelation were located.
Here is what Jesus Christ gave to The Apostle John to write about the church in Sardis:
"And to the angel of the church in Sardis write:"
"The words of Him who has the seven spirits of God and the seven stars. 'I know your works; you have the name of being alive, and you are dead. Awake, and strengthen what remains and is on the point of death, for I have not found your works perfect in the sight of My God. Remember then what you received and heard; keep that, and repent. If you will not awake, I will come like a thief, and you will not know at what hour I will come upon you."
"Yet you have still a few names in Sardis, people who have not soiled their garments; and they shall walk with Me in white, for they are worthy. He who conquers shall be clad thus in white garments, and I will not blot his name out of the book of life; I will confess his name before My Father and before His angels. He who has an ear, let him hear what the Spirit says to the churches."
(Revelation 3:1-6 RSV)
