Jaehaerys I’s Compilation of the Great Code

Jaehaerys I’s Compilation of the Great Code was a long-term royal project to bring order to Westeros’s many conflicting laws and precedents. Begun in the autumn of 55 AC, it aimed to make a realm ruled by one king more coherent in law, while confronting the practical difficulty of gathering and reconciling traditions that had accumulated across generations of local rule.

Origins and purpose

The project began after Jaehaerys Targaryen was unable to locate his niece, Elissa Farman. In the quiet of the Red Keep’s library, he turned to the work of codifying, organizing, and reforming the kingdom’s laws. He was assisted by Septon Barth, Grand Maester Benifer, Lord Albin Massey, and Queen Alysanne, a group the king called his smaller council.

The problem they faced was not simply that Westeros contained seven kingdoms. Each kingdom had its own laws and customs, and substantial differences existed within them as well. Lord Albin Massey described a past in which the number of kingdoms shifted continually with wars and changes of succession; the laws shifted too, according to the inclinations and beliefs of individual rulers. Over thousands of years, those changes had produced a mass of contradictory precedents.

A fragmented legal inheritance

Before the compilation, local authority remained powerful. Under Aegon the Conqueror, the existing feudal structures and laws of inheritance and succession had been left in place. Lords great and small retained the right of pit and gallows on their lands, and the privilege of the first night continued wherever it had been customary. These arrangements preserved established local powers even as the Crown claimed authority over the realm as a whole.

Royal rule had also begun to impose common standards in particular areas. Aegon made the King’s Peace the realm’s first law, requiring lesser disputes to be settled by liege lords and conflicts between great houses to be adjudicated by the Crown. He regularized customs, duties, and taxes, while exempting the Faith’s holy men, women, lands, and possessions from taxation and affirming the Faith’s courts’ right to judge its own clergy. Such measures provided precedents for kingdom-wide governance, but they did not erase the many local legal traditions that Jaehaerys’s project confronted.

Scale and method

Jaehaerys regarded legal confusion and disorder as intolerable and set the smaller council to the task of sorting through the inherited law. The work was necessarily gradual: simply collecting, organizing, and studying existing laws would take two years, while the reforms that followed would continue for decades. The compilation therefore began not with an instant replacement of every local rule, but with sustained investigation of laws and precedents that had accumulated across the realm.

Septon Barth ultimately contributed three times as much as any other man to the Books of Law that resulted. The title Great Code of Septon Barth reflects the scale of that contribution, even though the undertaking began as the king’s project and depended on the smaller council’s assistance.

Place in Jaehaerys’s reforms

The Great Code was one part of a broader effort to govern through law. During Jaehaerys’s reign, Queen Alysanne’s laws also altered established customs: the abolition of the lord’s right to the first night made taking a bride without her consent a crime of rape, whether the offender was lord or peasant. That measure was a distinct royal decree rather than a stated component of the compilation, and it illustrates how legal change could reach practices that earlier policy had left in place.

The Great Code’s importance lies in its response to a realm where one crown presided over many overlapping legal inheritances. Its ambition was not merely to collect old rules, but to make law more intelligible and governable across the Seven Kingdoms; the length of the work itself records how deeply local custom and conflicting precedent were rooted.
