アリクブケ
Kublai imprisoned Ariq Böke, but did not immediately punish him. Kublai's supporters wanted retribution, so Kublai ignored Ariq Böke for a year as punishment. He conducted a purge to eliminate officials in the Mongol government who sympathized with Ariq Böke. Kublai accused Bolghai, an important Mongol official who served under Möngke, of treachery for conspiring with Ariq Böke. Kublai authorized the execution of Bolghai and other Ariq Böke supporters. Kublai summoned a kurultai to decide a punishment for Ariq Böke and solidify his own claim to the throne. Kublai was reluctant to punish his brother without public support of the Mongol nobility. Ariq Böke died mysteriously in 1266 while still imprisoned, leading to speculation that Kublai had secretly poisoned him.
