prominent examples of legislatures are the houses of parliament in london, the congress in washington d.c., the bundestag in berlin, the duma in moscow, the parlamento italiano in rome and the "assemblée nationale" in paris. by the principle of representative government people vote for politicians to carry out "their" wishes. although countries like israel, greece, sweden and china are unicameral, most countries are bicameral, meaning they have two separately appointed legislative houses.
