Sayid Ahmad I (Turki/Kypchak and Persian: سید احمد خان) was Khan of the Golden Horde from 1427 or 1433[1] until 1455. Unlike the last five of six khans, Ahmad was a younger son of Tokhtamysh.
While he died before the Horde dissolved, historians believe that Sayid Ahmad was responsible for creating the conditions in the khanate which allowed it to happen.[2]
