In Egyptian history, the Upper and Lower Egypt period (also known as The Two Lands) was the final stage of prehistoric Egypt and directly preceded the unification of the realm. The conception of Egypt as the Two Lands was an example of the dualism in ancient Egyptian culture and frequently appeared in texts and imagery, including in the titles of Egyptian pharaohs.
The Egyptian title zmꜣ-tꜣwj (Egyptological pronunciation sema-tawy) is usually translated as "Uniter of the Two Lands"[1] and was depicted as a human trachea entwined with the papyrus and lily plant. The trachea stood for unification, while the papyrus and lily plant represent Lower and Upper Egypt.
Standard titles of the pharaoh included the prenomen, quite literally "Of the Sedge and Bee" (nswt-bjtj, the symbols of Upper and Lower Egypt)[2] and "lord of the Two Lands" (written nb-tꜣwj). Queens regnant were addressed as pharaohs and male. Queens consort might use a feminine versions of the second title, "lady of The Two Lands" (nbt-tꜣwj), "mistress of the Entire Two Lands" (hnwt-tꜣwy-tm), and "mistress of the Two Lands" (hnwt-tꜣwy).[3]
