Ibn Saud's reconquest of Riyadh in 1902 began the Third Saudi State, known successively as the Emirate of Riyadh (1902-1913), Emirate of Nejd and Hasa (1913-1921), and Sultanate of Nejd (1921-1926/1927), before proclamation as the Kingdom of Hejaz and Nejd and finally the Kingdom of Saudi Arabia in 1932.
Renamed and elevated to the Kingdom of Saudi Arabia on 23 September 1932 (already canonical, id: saudi-arabia) - the same continuous Wikidata entity/dynasty, not a conquest or succession break.
The atlas holds 2 border frames for Emirate of Riyadh / Nejd and Hasa (Third Saudi State, pre-Kingdom) — the shape you scrub through changes in 1902 · 1922.
