Proselytism in the context of "Arya Samaj"

Christianity in the 1st century covers the formative history of Christianity from the start of the ministry of Jesus (c. 27–29 AD) to the death of the last of the Twelve Apostles (c. 100) and is thus also known as the Apostolic Age. Early Christianity developed out of the eschatological ministry of Jesus. Subsequent to Jesus' death, his earliest followers formed an apocalyptic messianic Jewish sect during the late Second Temple period of the 1st century. Initially believing that Jesus' resurrection was the start of the end time, their beliefs soon changed in the expected Second Coming of Jesus and the start of God's Kingdom at a later point in time.

Paul the Apostle, a Pharisee Jew, who had persecuted the early Christians of the Roman Province of Judea, converted c. 33–36 and began to proselytize among the Gentiles. According to Paul, Gentile converts could be allowed exemption from Jewish commandments, arguing that all are justified by their faith in Jesus. This was part of a gradual split between early Christianity and Judaism, as Christianity became a distinct religion including predominantly Gentile adherence.

Conversion to Islam, also known within Islam as reversion, is adopting Islam as a religion or faith. Conversion requires a formal statement of the shahādah, the credo of Islam, whereby the prospective convert must state that "there is none worthy of worship in truth except Allah and Muhammad is the messenger of Allah". Proselytism of the faith is referred to as "dawah", and missionary efforts have been promoted since the dawn of the religion in the 7th century.

Christian mission to Jews, evangelism among Jews, or proselytism to Jews, is a subset of Christian missionary activities which are engaged in for the specific purpose of converting Jews to Christianity.

According to the Hebrew Bible, the Tribe of Issachar (Hebrew: יִשָּׂשכָר/יִשְׂשָׂכָר, Modern: Yīssaḵar, Tiberian: Yīssāḵār) was one of the twelve tribes of Israel and one of the ten lost tribes. In Jewish tradition, the descendants of Issachar were seen as being dominated by religious scholars and influential in proselytism. The sons of Issachar, ancestors of the tribe, were Tola, Phuvah, Job and Shimron.

The fiscus Iudaicus or fiscus Judaicus (Latin for 'Jewish tax') was a tax imposed on Jews in the Roman Empire after the destruction of Jerusalem and its Temple in AD 70.

The fiscus Iudaicus replaced the traditional half-shekel Temple tax which had been paid annually by Jews for the maintenance of the Temple in Jerusalem. The new tax redirected those funds to the reconstruction of the Temple of Jupiter Optimus Maximus in Rome, which had been destroyed during the Year of the Four Emperors. The redirection of these funds represented a significant humiliation for the Jewish population of the empire. The tax continued even after the Capitoline Temple was rebuilt, contributing to Roman finances and also serving as a deterrent against proselytism and conversion to Judaism.

Open-air preaching, street preaching, or public preaching is the act of evangelizing a religious faith in public places. It is an ancient method of proselytizing a religious or social message and has been used by many cultures and religious traditions, but today it is usually associated with evangelical Protestant Christianity. Supporters of this approach note that Jesus and many of the Old Testament prophets often preached about God in public places. It is one of the oldest approaches to evangelism.
