The Government of the U.S. State of Nebraska, established by the Nebraska Constitution, is a republican democracy modeled after the Federal Government of the United States. The state government has three branches: the executive, the legislative, and the judicial. Through a system of separation of powers, or "checks and balances," each of these branches has some authority to act on its own, and also some authority to regulate the other two branches, so that all three branches can limit and balance the others' authority. The State Government is based in Lincoln, the capital city of Nebraska.
