"The Territory of Iowa had a heated dispute with the State of Missouri over the boundary line between the two. Missouri's northern boundary was the parallel of latitude passing through the rapids of the river Des Moines. There were two rapids, eight or ten miles apart, and the dispute was as to which of these was meant, Missouri insisting upon the northern and Iowa on the southern one. Each government tried to enforce its authority. In the attempt to do this, Governor Boggs, of Missouri, called out the militia; then Governor Lucas, of Iowa, called out his soldiers. Five hundred men were under arms. On the petitions of Iowa and Missouri, Congress authorized a suit to settle the controversy, which resulted in a decision favorable to Iowa.
"Further treaties were made with the Indians by which additional land was gained for settlement. A large tract of land was opened to settlers on May 1, 1843, and on the preceding night there was a rush of land seekers similar to that which had occurred ten years before; over a thousand families settled in the newly opened lands within twelve hours.
"The very rapid increase in population led to a demand for statehood. On July 31, 1840, the Territorial Legislature passed an Act by which it called for a vote of the people on the question of assembling a constitutional convention. In August the vote was taken, resulting in the defeat of the proposition by a vote of two thousand nine hundred and seven to nine hundred and thirty-seven. Another vote was taken in 1842, resulting in the same way, but on February 12, 1844, the suggestion of a constitutional convention met the approval of the majority of the electors, and without waiting for a Federal Enabling Act a Constitution was adopted by a convention which met at Iowa City, October 7, 1844, and finished its work November 1st of the same year. This Constitution was submitted to Congress by the Territorial delegate.
"Here again there was the effort to balance a northern and southern State. Maine had been admitted into the Union in 1820, and Missouri in 1821; Arkansas in 1836, and Michigan in the next year. Now, it was proposed to admit Florida with Iowa. At this time Florida was much below the required population. The Congressional debate on the subject was a long and interesting one and brought out clearly the growing jealousy between North and South. This feeling was especially strong at this time because of the probability that several southern slaveholding States might be formed from Texas.
"There was furthermore a dispute of considerable importance over the general boundary of Iowa. The Constitution submitted to Congress by the Territorial delegate provided that the boundary should be as follows: 'Beginning in the middle of the main channel of Mississippi River opposite the mouth of Des Moines River; thence up the said River Des Moines in the middle of the main channel thereof, to a point where it is intersected by the old Indian boundary line, or line run by John C. Sullivan in the year 1816; thence westwardly along said line to the old northwest corner of Missouri; thence due west to the middle of the main channel of Missouri River; thence up in the middle of the main channel of the river last mentioned to the mouth of Sioux or Calumet River; thence in a direct line to the middle of the main channel of St. Peter's River, where Watonwan River (according to Nicollet's map) enters the same; thence down the middle of the main channel of said river to the middle to the main channel of Mississippi River; thence down the middle of the main channel of said river to the place of beginning.'
"An amendment was proposed in Congress which substituted the following in place of the boundary as given above: 'Beginning in the middle of St. Peter's River, at the junction of Watonwan or Blue Earth River; with the said River St. Peter's running thence due east to the boundary line of the Territory of Wisconsin in the middle of Mississippi River; thence down the middle of the last-named river with the boundary line of the Territory of Wisconsin and state of Illinois to the northeast corner of the state of Missouri in the said River Mississippi; thence westwardly with the boundary line of said State of Missouri to a point due south from the place of beginning; thence due north to the place of beginning in said St. Peter's River.'
"Of especial interest was the attitude taken by Samuel F. Vinton, representative from Ohio, in regard to the admission of Iowa. He believed that the Western States should be small in area in order that the West might not be deprived of its share in the government of the nation. It seemed to him that the policy so far pursued in the West had been wrong because the States were so large that they were sure to contain two or three times as large a population as the Atlantic States. There was at the time a provision under consideration that Florida might be divided, when either East or West Florida should contain a population of thirty-five thousand. Vinton contended that if Florida was to be divided, there should be a provision for dividing Iowa, because it was safer to give political power to the West than to the Atlantic States, for the West was the great conservative power of the Union. He stated that though the spirit of disunion might exist in the North and in the South, it could not live in the West, because the interests of the West were inseparably connected with both, and it would hold the two sections together, because it had no prejudice against either North or South and, what was of greater importance, the West was a grain growing country, and so must look equally to the manufacturing North and the cotton growing South for its market. Therefore the West must be conservative whether it wished to be or not. Vinton believed that instead of five there should have been at least twelve States in the old Northwest, and that to partly offset this injustice, small States should be formed west of the Mississippi. After considerable debate in the House, the bill for the admission of Iowa passed that body and was transmitted to the Senate, which it passed March 3, 1845.
"After a vote for admission, the constitution was submitted to the people of Iowa, who made serious objections to it. One objection was directed against the small salaries to be paid, which, it was feared, would result in getting only inferior men for official positions. The restrictions on banks and corporations proved an unpopular feature. The limitation placed upon the extent of territory claimed by Iowa was unsatisfactory to many, though the State would still have an area of forty-four thousand three hundred square miles. This reduction of area was the greatest objection, so that when the vote was taken many who were in favor of statehood voted against forming a state of such reduced area, and the Constitution was rejected by a vote of seven thousand and nineteen to six thousand and twenty-three.
"The governor called a special session of the legislature, and a bill for the re-submission of the constitution was passed over his veto. This was defeated by the people in August, 1845. On January 17, 1846, an Act was passed which provided for a new constitutional convention. This body came together in May and adopted a new constitution which did not differ greatly from the earlier instrument. The boundaries given in it were a compromise between those originally asked by the people and those granted by Congress. The matter was actively discussed in Congress when the new constitution with the changed boundaries came before that body, but the arguments were essentially the same as those previously advanced. An exciting campaign followed in Iowa, and the constitution was adopted, August 3, 1846, by a small majority. On the 4th of August the president signed the bill which settled the boundary question in accordance with the second constitution, and an Act was passed December 28, 1846, by which Iowa was admitted into the Union."
