It was on Thursday morning, December 3, 1846, that the Senators and Representatives assembled together in the hall of the House of Representatives in the Old Stone Capitol to witness the inauguration of the new Governor. Here in the presence of the General Assembly Judge Charles Mason, Chief Justice of the Supreme Court of the Territory, administered the oath of office to the first Governor of the State of Iowa. Twelve days after the inauguration of the State Governor at Iowa City, Mr. Dodge presented to the House of Representatives at Washington a copy of the Constitution of Iowa. The document was at once referred to the Committee on the Territories, from which a bill for the admission of Iowa into the Union was reported through Mr. Stephen A. Douglas on December seventeenth. It was made a special order of the day for Monday, December twenty-first, when it was debated and passed. Reported to the Senate on the twenty-second, it was there referred to the Committee on the Judiciary. This Committee reported the bill back to the Senate without amendment. After some consideration it passed the Senate on December twenty-fourth. Four days later it received the approval of President Polk. The existence of Iowa as one of the Commonwealths of the United States of America dates, therefore, from the TWENTY-EIGHTH DAY OF DECEMBER, ONE THOUSAND EIGHT HUNDRED AND FORTY-SIX. The act of admission declares that Iowa is "admitted into the Union on an equal footing with the original States in all respects whatsoever," and provides that all the provisions of "An Act supplemental to the Act for the Admission of the States of Iowa and Florida into the Union" approved March 3, 1845, shall continue in full force "as applicable to the State of Iowa." The conditions contained in the provisions of this act, which had been substituted by Congress in lieu of the provisions of the Ordinance submitted by the Convention of 1844, were finally accepted by the General Assembly of the State in an act approved January 17, 1849.
