Royal Standardization of Customs, Duties, and Taxes

Royal Standardization of Customs, Duties, and Taxes was Aegon’s attempt to make revenue collection more consistent across the newly united realm. It established a royal role in setting common fiscal rules while leaving much local governance intact. Later episodes under Jaehaerys and Rhaenyra revealed the policy’s practical stakes: taxes could fund royal priorities, but poorly designed or excessive levies also diverted trade, halted construction, and deepened hostility toward the Crown.

A Common Royal Framework

Before the Conquest, each port and petty lord could impose charges as it pleased, extracting what it could from tenants, smallfolk, and merchants. Aegon issued decrees to regularize customs, duties, and taxes throughout the realm, making these matters a concern of royal government rather than leaving each locality to set charges without a common framework.

The fiscal reforms formed part of a broader governing balance. Aegon generally left local laws, inheritance customs, feudal structures, and the powers of individual lords in place; his intervention focused on matters he considered essential to the peace and functioning of the realm. He also exempted the holy men and women of the Faith, along with their lands and possessions, from taxation, while affirming the Faith’s courts’ authority over accused religious officials. Royal fiscal authority therefore coexisted with preserved local privileges and a distinct religious jurisdiction.

The Regency’s Failed Levies

The policy’s limits became evident during Jaehaerys’s minority. The Crown’s treasury had been depleted by Maegor’s wars and the expenses of the young king’s coronation and his mother’s wedding. The regent, Lord Rogar, also wanted the Dragonpit completed, but the royal government lacked the money to finish it. Edwell Celtigar, serving as master of coin, responded by imposing new burdens on the smallfolk and businesses of King’s Landing: port fees were tripled, some goods were taxed both entering and leaving the city, and innkeepers and builders faced new levies.

The measures failed to replenish the treasury. Building slowed, inns emptied, and merchants diverted ships from King’s Landing to Driftmark, Duskendale, and Maidenpool to avoid the charges. The new taxes made Edwell Celtigar deeply unpopular, while the Crown’s inability to pay its builders brought work on the Dragonpit to a halt. The episode showed that royal power to impose charges did not guarantee effective collection: when levies made trade less attractive, commerce and construction contracted instead.

Loans and Selective Taxation

After Jaehaerys assumed personal rule, Rego Draz addressed the immediate shortfall by negotiating three substantial loans, from the Iron Bank of Braavos and rival banks in Tyrosh and Myr. Securing the loans allowed work on the Dragonpit to resume, with builders and stonemasons again at work on the Hill of Rhaenys. But Jaehaerys and Rego regarded borrowing as temporary relief, not a lasting answer to the Crown’s financial problem.

Rather than raise port fees or demand gold directly from the lords, Jaehaerys chose to tax costly imported goods. The schedule included silk, samite, cloth-of-gold and cloth-of-silver, gemstones, Myrish lace and tapestries, Dornish wines but not Arbor wines, Dornish sand steeds, and finely made armor and helms from Tyrosh, Lys, and Pentos. Spices from beyond the Jade Gates, including pepper, cloves, saffron, nutmeg, and cinnamon, were taxed most heavily. The approach sought revenue from goods the wealthy wanted without repeating the broad charges on ordinary commerce that had damaged King’s Landing’s trade.

Reimposition and Reversal

During Rhaenyra’s rule in King’s Landing, Bartimos Celtigar faced another severe shortage of royal funds. Aegon II had taken control of the treasury, spent the money left in the city, and placed much of the remaining wealth beyond Rhaenyra’s reach. Bartimos revived the earlier taxes associated with his ancestor Edwell and added further levies: wine and ale taxes were doubled, port fees tripled, shopkeepers were charged for keeping their doors open, and innkeepers owed a silver stag for every bed. Entry and exit charges were restored at three times their earlier level, and property was taxed according to the land occupied, whether the holding was a wealthy merchant’s house or a beggar’s hovel.

After Rhaenyra’s fall, Tyland Lannister abolished those taxes as part of his effort to restore trade and rebuild the kingdom. He also set aside a million golden dragons in loans for lords whose lands had been damaged during the Dance. The repeated movement from common rules to exceptional levies, and then to their repeal, makes the fiscal policy’s political consequences clear: raising revenue could serve urgent royal needs, but charges that burdened commerce and residents could undermine the recovery they were meant to finance.
