XXII

XXII is the Roman numeral representing the number 22. It is formed by the symbols X, X, and II, which together sum to 10 + 10 + 2. In modern usage, XXII denotes twenty-two in contexts where Roman numerals are preferred for stylistic or conventional reasons.

In everyday and formal contexts, XXII appears in numbering systems such as chapters, sections, editions, or lists that use Roman numerals. It can label sequences, volumes, or events, and is sometimes used in film titles, music releases, or architectural inscriptions to evoke classical styles.

Historical scholarship also uses Roman numerals to designate dynasties or eras. Dynasty XXII of ancient Egypt is commonly identified as the Libyan-Bubastid dynasty, dating roughly to the late 10th to early 8th centuries BCE.
