2Illinois experienced a time of intense land speculation in the 1830s that resulted in a number of “paper towns,” settlements that were platted and available for sale but where few or no people actually lived. Many of the proprietors of these settlements abandoned them during and after the Panic of 1837. As a result, the General Assembly received a large number of petitions for vacation during their sessions from 1838 to 1841. In 1841, the legislature passed an act setting parameters for proprietors to vacate town plats themselves. Vacating a plat gave owners greater flexibility in the use, fencing, and sale of the property.
