Sister republic

Sister republics (French: république sœur, pronounced [ʁepyblik sœʁ] ) were satellite states of the French Republic set up in the territories captured by the victorious French Army during the French Revolutionary Wars; like their protector, they were revolutionary republics. This became particularly evident after the First French Empire was established in 1804, after which France annexed several sister republics and transformed the remainder into monarchies ruled by members of the House of Bonaparte.
