Summary: The Bible only mentions the deaths of two apostles, James who was put to death by Herod Agrippa I in 44 AD and Judas Iscariot who committed suicide shortly after the death of Christ. The details of the deaths of three of the apostles (John, the Beloved, Bartholomew and Simon the Canaanite) are not known at all, either by tradition or early historians. The deaths of the other seven apostles are known by tradition or the writings of early Christian historians. According to traditions and the Bible, eight of the Apostles died as Martyrs. At least two of the Apostles, Peter and Andrew were crucified.
Simon surnamed Peter died 33-34 years after the death of Christ. According to Smith’s Bible Dictionary there is “satisfactory evidence that he and Paul were the founders of the church at Rome, and died in that city. The time and manner of the apostle’s martyrdom are less certain. According to the early writers, he died at or about the same time with Paul, and in the Neronian persecution, A.D. 67,68. All agree that he was crucified. Origen says that Peter felt himself to be unworthy to be put to death in the same manner as his Master, and was therefore, at his own request, crucified with his head downward.”
James the son of Zebedee: He was put to death by Herod Agrippa I shortly before the day of the Passover, in the year 44 or about 11 years after the death of Christ. From Acts 12: 1-2.
John: No death date given by early writers. Death date is by conjecture only and is variously assigned as being between 89 AD to 120 AD
Andrew: No accurate death date given. A variety of traditions say he preached in Scythia, in Greece, in Asia Minor and Thrace. He is reported to have been crucified at Patrae in Achaia.
Philip: Again, the Bible does not say when he died nor do we have accurate information. According to tradition he preached in Phrygia, and died at Hierapolis. Update: FoxNews July 27, 2011 Tomb of the Apostle Phillip is found in Hierapolis.
Bartholomew: There is no information concerning his death, not even by tradition
Matthew: He must have lived many years as an apostle, since he was the author of the Gospel of Matthew which was written at least twenty years after the death of Christ. There is reason to believe that he stayed for fifteen years at Jerusalem, after which he went as missionary to the Persians, Parthians and Medes. There is a legend that he died a martyr in Ethiopia.
Thomas: The earlier traditions, as believed in the fourth century, say he preached in Parthia or Persia, and was finally buried at Edessa. The later traditions carry him farther east. His martyrdom whether in Persia or India, is said to have been by a lance, and is commemorated by the Latin Church on December 21 the Greek Church on October 6, and by the Indians on July 1.
James Alpheus : We know he lived at least five years after the death of Christ because of mentions in the Bible. According to tradition, James son of Alpheus was thrown down from the temple by the scribes and Pharisees; he was then stoned, and his brains dashed out with a fuller’s club.
Simon the Canaanite – No information either in the Bible or by tradition.
Jude (Thaddeus): according to tradition Jude taught in Armenia, Syria and Persia where he was martyred. Tradition tells us he was buried in Kara Kalisa in what is now Iran.
Judas Iscariot: Shortly after the death of Christ Judas killed himself. According to the Bible he hanged himself, (Matthew 27:5) at Aceldama, on the southern slope of the valley of Hinnom, near Jerusalem, and in the act he fell down a precipice and was dashed into pieces.
