If you take a handful of soil, you will get hundreds or even thousands of bacteria in it. The kingdom Monera is divided into two major groups, the Eubacteria (true bacteria) and the Archaebacteria (primitive bacteria). In 1938, Herbert F. Copeland proposed a four-kingdom classification by creating the novel Kingdom Monera of prokaryotic organisms; as a revised phylum Monera of the Protista, it included organisms now classified as Bacteria and Archaea. 4.
