The Taktikon Uspensky or Uspenskij is the conventional name of a mid-9th century Greek list of the civil, military and ecclesiastical offices of the Byzantine Empire and their precedence at the imperial court.
Nicolas Oikonomides has dated it to 842/843,[1] making it the first of a series of such documents (taktika) extant from the 9th and 10th centuries.
[2] The document is named after the Russian Byzantinist Fyodor Uspensky, who discovered it in the late 19th century in a 12th/13th-century manuscript (codex Hierosolymitanus gr.
39) in the library of the Eastern Orthodox Patriarchate of Jerusalem, which also contained a portion of the Kletorologion of Philotheos, a later taktikon.
