Democide refers to "the intentional killing of an unarmed or disarmed person by government agents acting in their authoritative capacity and pursuant to government policy or high command." The term was first coined by Holocaust historian and statistics expert, R.J. Rummel in his book Death by Government, but has also been described as a better term than genocide to refer to certain types of mass killings, by renowned Holocaust historian Yehuda Bauer. According to Rummel, this definition covers a wide range of deaths, including forced labor and concentration camp victims, extrajudicial summary killings, and mass deaths due to governmental acts of criminal omission and neglect, such as in deliberate famines like the Holodomor, as well as killings by de facto governments, i.e. killings during a civil war. This definition covers any murder of any number of persons by any government.
