Order of Terra
The Order of Terra was originally the highest-ranking of three orders of knighthood, the orders of Terra, Vland, and Sylea, used by the Sylean Federation to award citizens for extraordinary achievements and service. The Order of Terra was reserved for citizens who could trace their ancestry back to the Terran Confederation. The order was second only to the Order of the Cross of Arlea, which was reserved for planetary royalty and Federation nobles of equivalent rank.
When Cleon I created the Order of the Imperial Sunburst in Year 0, it came to outrank all other orders since he appointed its members in his capacity as emperor whereas he appointed members to the other orders in his capacity as Grand Duke of Sylea. Most new knights that would formerly had been inducted into the Order of Terra was instead inducted into the Order of the Imperial Sunburst or, after Year 17, its replacment, the Order of the Starship and Crown.
In 76 the orders of Vland and Sylea were repurposed as domain orders of the Domain of Vland and the Domain of Sylea, but the Order of Terra remained an order with little or no activity.
In 583, Jacquline I, as part of her strategy of finally integrating the rimward sectors of the Domain of Diaspora into the Imperium, renamed it the Domain of Sol and appointed an Archduke of Sol to impress the rimward client states, especially the Old Earth Union, with her commitment to respecting their interests. The defunct Order of Terra was revived to serve as the domain order of knighthood, allowing it to be ranked above the other domain orders, another sop to rimward pride.
In 716, the Archduchy of Sol lapsed after the death of the incumbent left no available heir who was not a member of the Solomani Party. With no archduke to appoint new members, the Order of Terra became moribund once more. Various attempts to keep it active were made from time to time with emperors making appointments to the order by special provision, but the last such appointment was in 882.
In 1002 Gavin revived the Order of Terra as a preliminary to appointing a new Archduke of Sol the next year. However, although it was considered heir to all of the Order of Terra's possessions and traditions, the order was renamed the Order of Sol and its seniority downgraded at the same time.
