Aegon’s Local-Law Preservation Policy

Aegon’s Local-Law Preservation Policy shaped how the Conqueror governed a realm made up of kingdoms with distinct laws and traditions. Rather than replace those systems with a single royal code, Aegon confirmed much of the existing order, while establishing the Crown’s authority to restrain private war, settle disputes between great houses, and regularize taxation. The result was a layered settlement: local lordship endured, but it operated within a newly asserted royal peace.

A Conquest that preserved local rule

Aegon allowed the lords of the conquered kingdoms to continue governing much as they had before. Existing feudal structures and laws of inheritance and succession remained unchanged, and lords both great and small retained the power of pit and gallows on their own lands. The Right of the First Night also remained where it had previously been customary. The policy thus made submission compatible with continuity: defeated lords could retain familiar authority and institutions under the new king.

That continuity did not mean that every kingdom had possessed identical laws, or that Aegon created a uniform system beneath the surface. His settlement preserved differences among the realms while recognizing the Crown as their common sovereign. It was a practical distinction between maintaining local governance and allowing the former kingdoms to wage war against one another as independent powers.

The King’s Peace and royal authority

Aegon’s chief concern was peace. Before the Conquest, conflicts between realms were frequent, and neighboring lords could settle disputes by force even within kingdoms described as peaceful. Under the King’s Peace, lesser lords and landed knights were expected to bring their disputes to their liege lords and accept judgment. Arguments between the great houses instead fell to the Crown. A lord who went to war without royal leave could be treated as a rebel and enemy of the Iron Throne.

This arrangement preserved local judicial authority but placed limits on its use in armed conflict. The Crown did not displace every lord’s court; it claimed the authority to prevent private wars from undoing the unity created by conquest. The policy’s central balance was therefore not between law and lawlessness, but between continuing local rule and a royal power that could intervene when disputes threatened the peace of the realm.

Taxes and the Faith

Aegon also regularized customs, duties, and taxes across the realm. Before this change, ports and individual lords could exact whatever amounts they could obtain from tenants, smallfolk, and merchants. Standardization gave the Crown a role in setting common expectations where local exactions had varied, without amounting to a wholesale replacement of local laws.

The settlement also accommodated the Faith. Aegon exempted its holy men and women, together with their lands and possessions, from taxation, and affirmed the Faith’s own courts’ right to try and sentence septons, Sworn Brothers, and holy sisters accused of misconduct. Although Aegon was not himself a godly man, he took care to cultivate the support of the Faith and the High Septon of Oldtown. Royal authority and religious jurisdiction thus remained distinct but coexisting parts of the realm’s governance.

Custom tested by royal decisions

The continued force of custom is illustrated by a case heard by Queen Rhaenys. A husband accused of beating his wife to death argued that he had acted within his lawful rights because she had been unfaithful, and produced the rod he had used to show that it was no thicker than his thumb. The woman’s brothers maintained that he had struck her a hundred times. After consulting maesters and septons, Rhaenys held that six blows were lawful under the religious reasoning she applied, but that the remaining ninety-four exceeded the permitted punishment. The judgment established the Rule of Six alongside the Rule of Thumb. In this instance, a familiar legal defense remained recognizable, but its reach was bounded by a royal decision.

A more sweeping change came under Jaehaerys I Targaryen. The second of the laws known among the smallfolk as Queen Alysanne’s Laws abolished the lord’s ancient Right of the First Night. The new decree reserved a bride’s maidenhead to her husband, whether the marriage had been joined before a septon or a heart tree, and defined taking her on her wedding night or another night as rape, whether the offender was a lord or a peasant. The policy of preserving existing customs was therefore not an absolute bar to royal reform: a practice Aegon had left in place could later be prohibited by royal decree.

Inheritance and the limits of continuity

Aegon’s preservation of existing inheritance and succession laws did not settle every later dispute over the Iron Throne. After Prince Aemon died, Jaehaerys passed over Aemon’s daughter Rhaenys and named her uncle Baelon heir. Queen Alysanne opposed the decision, left King’s Landing for Dragonstone, and remained estranged from Jaehaerys for two years, continuing to argue that Rhaenys and her children had been unfairly denied their rights.

At the Great Council of 101 AC, the lords chose Viserys Targaryen over Rhaenys’s son Laenor by a margin said to exceed twenty to one. The council’s result was understood as a precedent that the Iron Throne could not pass to a woman or through a woman to her male descendants. This later rule concerned royal succession; it should not be confused with a general repeal of the local inheritance laws Aegon had preserved. The distinction captures the settlement’s enduring tension: local traditions continued, while the Crown’s own authority and succession could be shaped by later decisions and precedents.
