In biological taxonomy, which level comes just after 'Domain'?

In biological taxonomy, the hierarchy of classification begins with the broadest category, which is the domain. Following this is the kingdom, making it the first descending category after domain. Kingdoms are subdivisions within domains that group together organisms that share fundamental traits and lineage. For example, within the domain Eukarya, organisms are classified into several kingdoms, including Animalia, Plantae, and Fungi. This hierarchical structure is essential for organizing the vast diversity of life into manageable groups for study and identification, creating a clear pathway from the broadest classification to more specific ones.
