There has been a proposal, not yet totally accepted, to divide the Kingdom Bacteria (or Monera) into two or more kingdoms. The most common division is into the Archaebacteria and the Eubacteria, which are often treated as subkingdoms under the five kingdom system. A more extreme proposal is to further divide the Archaebacteria into three kingdoms. References: Margulis, L., K. V. Schwartz, and M. Dolan. 1999.
