The name, before the Roman conquest in 146 B.C., of a strip of land between the gulf of Corinth in the north and Elis and Arcadia in the south, embracing twelve cities leagued together. The Achaean League was prominent in the struggle of the Greeks against Roman domination. It is probably due to this fact that the name was afterwards extended to the whole country south of Macedonia and Illyricum, corresponding approximately to modern Greece. During the Roman period Achaia was usually governed as a senatorial province. The Governor was an ex-Praetor of Rome, and bore the title of Proconsul. Corinth was the capital. When St. Paul came into Achaia ( Acts 18 ), Gallio, a brother of Seneca, was proconsul. His refusal to interfere in the religious affairs of the Jews and the tolerance of his administration favoured the spread of Christianity. In Corinth the Apostle founded a flourishing church. In his Second Epistle to the Corinthians, he salutes Christians "in all Achaia" (i, 1) and commends their charity (ix, 2).

Catholic Encyclopedia

Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.

No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
