Sassennach, the designation for the British, is used only twice in Ulysses, first in the Telemachus episode in which Buck Mulligan says with reference to Haines, the British houseguest, "The Sassenach wants his morning rashers." The word, Sassennach is used again in the Cyclops episode when Citizen in discussing the potato famine says, " But the Sassenach tried to starve the nation at home while the land was full of crops that the British hyenas bought and sold in Rio de Janeiro." The Sassennach is one of two powers that rule Ireland, the other power being the Catholic Church.

The British and the Catholic Church represent Usurpers in Ulysses. The signifier, Usurper, is used only once in Ulysses. It is:

"A voice, sweettoned and sustained, called to him from the sea.
Turning the curve he waved his hand. It called again. A sleek
brown head, a seal's, far out on the water, round.
Usurper."

Presumably, the use of the word "Usurper" refers to Buck Mulligan who has the key to Martello Tower in his possession by the end of the first episode. Stephen says:

"He wants that key. It is mine. I paid the rent. Now I eat his
salt bread. Give him the key too. All. He will ask for it. That was in
his eyes."

However, the note for "Usurper" cites the words of Telemachus to his mother's suitors in the Odyssey, and Hamlet's feeling towards his uncle Claudius.
