| One purpose of the Roman census was to determine the ordo to which an individual belonged. |
| Kublai received the viceroyalty over North China and moved his ordo to central Inner Mongolia. |
| In this ordo it is stated that the colour in Missa Defunctorum is niger vel violaceus. |
| Not all men who qualified for the ordo senatorius chose to take a Senate seat, which required legal domicile at Rome. |
| Kublai invited Haiyun, the leading Buddhist monk in North China, to his ordo in Mongolia. |
| A senator's son belonged to the ordo senatorius, but he had to qualify on his own merits for admission to the Senate itself. |
