1534 CE
Government authority under five-year-old Ratsadathirat proves to be weak.
Only five months after his nephew's ascension, Chairacha marches to Ayutthaya to stage a coup, kills his nephew, and takes the throne of Ayutthaya in 1534.
The new ruler appoints his brother Prince Tianracha (later Maha Chakkrapat) as the Uparaja but does not grant him the traditional title of King of Sukhothai, as Chairacha is trying to unite the two kingdoms by reducing the power of Sukhothai nobles.
He also calls the Sukhothai nobles to Ayutthaya to move them from their base at Pitsanulok and make Ayutthaya the sole center of authority.
