The Oregon Constitution was framed by a convention of 60 delegates chosen by the people. The convention met on the third Monday in August 1857 and adjourned on September 18 of the same year. On November 9, 1857, the Constitution was approved by the vote of the people of Oregon Territory. The Act of Congress admitting Oregon into the Union was approved February 14, 1859, and on that date the Constitution went into effect.
