1865 Iowa Senate election
In the 1865 Iowa State Senate elections, Iowa voters elected state senators to serve in the eleventh Iowa General Assembly. Following the expansion of the Iowa Senate from 46 to 48 seats in 1865, elections were held for 23 of the state senate's 48 seats. State senators serve four-year terms in the Iowa State Senate. The general election took place in 1865. Following the previous election in 1863, Republicans had control of the Iowa Senate with 41 seats to Democrats' five seats. To claim control of the chamber from Republicans, the Democrats needed to net 20 Senate seats. Republicans maintained control of the Iowa State Senate following the election with the balance of power shifting to Republicans holding 42 seats and Democrats having six seats (a net gain of 1 seat each for Republicans and Democrats).
