The Apostles were a group of twelve followers chosen by Jesus Christ to spread his teachings and establish the early Christian church. They played a crucial role in the formation of Christianity, witnessing Jesus' life, death, and resurrection. The names of the Apostles include Peter, James, John, and Judas Iscariot, among others. After Jesus' ascension, the Apostles traveled to various regions to preach the gospel and perform miracles. Their efforts laid the foundation for Christianity, and they are often regarded as the first leaders of the church. Many of their teachings and experiences are recorded in the New Testament.
