th 4 King of Rome Ancius Marcius 642 B.C. - 617 B.C. At the death of Tullus Hostilius, the senate appointed him as an interim leader. The assembly of the people elected him king. His first order of business was to return religious practices back to Rome. He did so by having them copied down and displayed to the public so they would never be forgotten. However Rome was attacked by the neighboring Latins and this took his focus away from religion. He conquered the Latins and removed them from their town. He settled them on the Aventine Hill. Some text say he made them citizens others state he started the plebian class. He was known for founding the port city of Ostia, and constructed the salt works there.
