This was nothing new. The king was simply following the then prevailing Southeast Asian administrative model of solar polities in which the high king ruled the core while semi-independent tributaries, autonomous viceroys, and governors actually controlled day-to-day administration and manpower. As such, the "King of Kings" governed only Pegu and the Mon country himself, leaving the rest of the realm to vassal kings in Ava, Prome, Lan Na, Lan Xang, Martaban, Siam, and Toungoo. He regarded Lan Na as the most important of all the vassal states, and spent much time there.
