History Within historical records, a man with the name Israel Atherton purchased the land around present-day Dallas City in 1836. He built a log cabin but he didn't seem to stay very long. He sold the land to John Finch, who built a village, which today is still recognized as, Dallas City. It was laid out in 1848, and named in honor of George Mifflin Dallas, 11th Vice President of the United States of America, from 1845 to 1849. A post office has been in operation at Dallas City since 1850. Abraham Lincoln Monument On October 23, 1858, Abraham Lincoln stopped in Dallas City, Illinois to deliver a speech.

A monument to represent Lincoln's visit sits on the Mississippi River on the Riverfront Park at the end of Oak St. According to the Dallas City Review newspaper, Democrats have tried several times to tear down the platform whilst giving his speech, but the many republican forces did not allow that to happen. However, there were supposed to be two stones with bronze plaques, one for Lincoln's visit, the other for President James Polk along with his Vice-President, George M Dallas. There is no information given as to why that other plaque was not included on the stone, but it is assumed Lincoln's was more impactful.

Douglas were running against one another for the US Senate. Geography Dallas City is located at (40.636565, -91.165256).
