 Frederick also had a very good relationship with his uncle, King Frederick William IV, who has been called "the romantic on the throne".Frederick grew up during a tumultuous political period as the concept of liberalism in Germany, which evolved during the 1840s, was gaining widespread and enthusiastic support.The liberals sought a unified Germany and were constitutional monarchists who desired a constitution to ensure equal protection under the law, the protection of property, and the safeguarding of basic civil rights.
