Previous to 1857, the present city of Jefferson was under the same government as the township. In 1857, the village of Jefferson was incorporated and represented in the township Board of Supervisors. This continued until 1878, when an act "to incorporate the citv of Jefferson" was passed by the Legislature of Wisconsin and approved March 19 of that year, since which date the whilom town and village has been considered as a municipal corporation, entitled to certain privileges and immunities thereunto appertaining, in consideration of securing to the citizens life, liberty and the pursuit of happiness.
