Charles Lawrence Robinson was an American politician who served in the California State Assembly from 1851 to 1852, and later as the first Governor of Kansas from 1861 until 1863. He was also the first governor of a US state to be impeached by a state legislature, although he was found not guilty during subsequent State Senate impeachment trial and was not removed from office. After his time as governor he served in the Kansas Senate from 1873 to 1881. To date, he is the only governor of Kansas to be impeached.

The Kansas Senate is the upper house of the Kansas Legislature, the state legislature of the U.S. State of Kansas. It is composed of 40 senators elected from single-member districts, each with a population of about 73,000 inhabitants. Members of the Senate are elected to a four-year term. There is no limit to the number of terms that a senator may serve. The Kansas Senate meets at the Kansas State Capitol in Topeka.
