Josiah or Yoshiyahu ( /dʒoʊˈsaɪ.ə/ or /dʒəˈzaɪ.ə/;Hebrew: יֹאשִׁיָּהוּ, Modern Yoshiyyáhu Tiberian Yôšiyyāhû, literally meaning "healed by Yahweh" or "supported of Yahweh"; Greek: Ιωσιας; Latin: Josias; c. 649–609 BC) was a king of Judah (641–609 BC) who instituted major reforms. Josiah is credited by most historians with having established or compiled important Jewish scriptures during the Deuteronomic reform that occurred during his rule.

Josiah became king of Judah at the age of eight, after the assassination of his father, King Amon, and reigned for thirty-one years, from 641/640 to 610/609 BC.

He is also one of the kings mentioned in the genealogy of Jesus in the Gospel of Matthew.

Josiah was the son of King Amon and Jedidah, the daughter of Adaiah of Bozkath. His grandfather Manasseh was one of the kings blamed for turning away from the worship of Yahweh. Manasseh adapted the Temple for idolatrous worship. Josiah's great-grandfather was King Hezekiah who was a noted reformer.

Josiah had four sons: Johanan, Eliakim (born c. 634 BC) by Zebudah the daughter of Pedaiah of Rumah, Mattanyahu (c. 618 BC) and Shallum (633/632 BC) both by Hamutal, the daughter of Jeremiah of Libnah.

Josiah Warren (1798 - April 14, 1874) was an individualist anarchist, inventor, musician, and author in the United States. He is widely regarded as the first American anarchist, and the four-page weekly paper he edited during 1833, The Peaceful Revolutionist, was the first anarchist periodical published, an enterprise for which he built his own printing press, cast his own type, and made his own printing plates.

Warren was born in Boston, Massachusetts in 1798. He showed an early talent for music and was a member of the "Old Boston Brigade Band" at an early age. He married at age 20 and in 1821 moved to Cincinnati, Ohio where he worked as a music teacher and orchestra leader. He invented a tallow-burning lamp in 1821 and manufactured his invention for a number of years in Cincinnati.

In 1825, Warren became aware of the "social system" of Robert Owen and began to talk with others in Cincinnati about founding a communist colony. When this group failed to come to agreement about the form and goals of their proposed community, Warren "sold his factory after only two years of operation, packed up his young family, and took his place as one of 900 or so Owenites who had decided to become part of the founding population of New Harmony, Indiana." The Cincinnati colony was attempted without Warren's involvement, but failed. Warren traveled by flat-boat from Cincinnati, arriving in New Harmony in early May, 1825. By 1827, he had returned to Cincinnati, convinced that the complete individualization of interests was necessary to cooperation. He considered Owen's experiment "communism," which he rejected in no uncertain terms, but he developed a warm and lasting respect for Robert Owen and his sons. One of his earliest writings, published in The March of Mind in 1827, attests to this, as do later writings.
