The taxonomic group that includes kingdoms and all other levels of taxonomy is the **domain**.
Domains are the highest level in the current system of biological classification. They encompass all forms of life and are further divided into kingdoms. The three main domains are Bacteria, Archaea, and Eukarya.
Within each domain, there are multiple kingdoms that further classify organisms based on shared characteristics. For example, within the Eukarya domain, you have kingdoms such as Plantae, Animalia, Fungi, and Protista.
Therefore, when considering the hierarchy of biological classification, the domain is the broadest level that includes kingdoms and all other levels of taxonomy within it.
