At the time, there were only two kingdoms: plantae and animalia. Only until later were different species found.
Archaea, Bacteria, and Eukarya
The three-domain system is a biological classification introduced by Carl Woese et al. in 1990[1][2] that divides cellular life forms into archaea, bacteria, and eukaryote domains. In particular, it emphasizes the separation of prokaryotes into two groups, originally called Eubacteria (now Bacteria) and Archaebacteria (now Archaea). Woese argued that, on the basis of differences in 16S rRNA genes, these two groups and the eukaryotes each arose separately from an ancestor with poorly developed genetic machinery, often called a progenote. To reflect these primary lines of descent, he treated each as a domain, divided into several different kingdoms. Woese initially used the term "kingdom" to refer to the three primary phylogenic groupings, and this nomenclature was widely used until the term "domain" was adopted in 1990.[2]
Archaea,Bacteria,Eukarya
Bacteria and Archaea domains include prokaryotic organisms.Eukarya domain includes Eukaryotic organisms.
because he was stupid;because he wasnt able to discover it
Bacteria and Archaea
Prokaryotes are classified into two main domains: Bacteria and Archaea. These domains are based on differences in their genetic makeup, cellular structure, and metabolic processes. Bacteria are more commonly known and include a wide variety of single-celled organisms, while Archaea are less well-understood but are known to thrive in extreme environments.

Archaea, Bacteria, and Eukarya
Kingdom Monera includes bacteria and archaea. Some common examples of bacteria are E. coli, Streptococcus, and Salmonella. Archaea examples include Methanogens, Halophiles, and Thermophiles.

Archaea,Bacteria,Eukarya
bacteria and archea
The two groups of organisms that include all prokaryotes are Bacteria and Archaea.
Three domains are : Archaea, Bacteria, and Eukarya Domains Archaea and Bacteria both include single-cell prokaryotes. Domain Eukarya includes all organisms made of eukaryotic cells
