This country had a senate like the united states has today?

The Roman Republic had a senate that functioned similarly to the United States Senate. The Roman Senate was a body of elders (senatores) who advised and assisted the magistrates of the Roman Republic, and which later became the supreme governing body of the Roman Empire. The Roman Senate was composed of members from the aristocracy and had a number of functions, including passing laws, approving treaties, and confirming appointments to public office.
