The Repersenative Reorganizations of 1910 was a major reform bill, stripping most repersenation from rural areas and giving it to urban consistutencies.
At the time of the empire's creation, both Prussia and Holy Germania were roughly two-thirds rural. Within 20 years, the situation was reversed; the cities and towns accounted (and still does) for two-thirds of the population. However, in both the kingdom and the empire, the constituencies were never redrawn to reflect the growing population and influence of the cities and towns. This meant that rural areas were grossly overrepresented from the 1890s until 1910. The Reorganizations solved this and the entire structure of both houses was changed, taking away some members and adding others. The Reorganizations passed by a wafer-thin majority in the Imperial Senate and was signed by Emperor Willhelm II of Holy Germania on 20 January 1911.
