Palpatine estava se referindo à Ruusan Reformation , um evento onde a República foi reformada e reestruturada. Ocorreu cerca de 1.000 anos antes de Palpatine fazer a declaração. Essencialmente, uma nova república foi criada.
A República original começou em cerca de 25.000 ABY. A moderna Ordem Jedi começou em cerca de 26.000 ABY. Então os Jedi serviram a República por toda a sua existência.
Isso foi criado especificamente para evitar um erro de continuidade.

The Ruusan Reformation was introduced in the timeline in order to explain several differences between the Old Republic as presented in the comics, and the one which appeared in the prequel trilogy.
In the Expanded Universe, the Republic is well established to be extant for 25,000 years, based on Obi-Wan Kenobi's line in A New Hope that the Jedi had been "the guardians of peace and justice in the Old Republic" "for over a thousand generations." For a long time, EU sources were the only works set during the Republic era—most notably the popular Tales of the Jedi sagas. However, in Attack of the Clones, Palpatine mentioned the Republic had "stood for a thousand years." This at first seemed to conflict with both the C-canon EU history and the G-canon internal continuity in the films. However, the Ruusan Reformation—in which the Republic is reorganized following the already-established defeat of the Sith a thousand years prior to the films at the Seventh Battle of Ruusan—was invented by subsequent writers to give an alternate explanation on Palpatine's line, thus bringing all these sources into relative harmony through a retcon. It also explains how Sio Bibble could claim, in Attack of the Clones, that there had not been a full-scale war since the formation of the Republic.
