Z was actually removed from þe latin alphabet in 300 bce and english used runes until þe 800s and 900s ce. It was removed because at þe time it wasn't needed in latin (þe sound it makes today was already represented by s and only occurred between voiced sounds and it may have made þe sound of þe zz in pizza which isn't in latin). It used to be after f and was readded to transcribe greek along wiþ þe addition of y for þe sound upsilon made before it made þe same sound as i when greece becakme part of rome. It was replaced by g by a teacher named Spurius Carvillius Ruga. It used to be one of þe sounds c made and j was originally made for þe sound y makes in english
