The Third Tikal–Calakmul War was the third in a series of wars between Tikal and Calakmul, (Tikal–Calakmul wars) two of the Major superpowers of the Maya Civilization during the classic period. During the third war, the vassal state of Quiriguá played an important role when it declared independence from Copán, Tikal's closest ally in the south, and then allied itself with Calakmul. Before Quiriguá After Calakmul's defeat in 695 (9.13.2.14.19 on the Maya calendar) violence continued between it and Tikal but for the most part died down. Then again in 720 (9.14.8.3.9) conflicts slowly started up. Despite Tikal being more prosperous Naranjo, Dos Pilas, and El Peru remained under Calakmul's control. Between 733 and 736 Tikal imprisoned a noble from Calakmul after a victorious battle. His capture was commemorated by the building of an altar that has a sculpture of him bound by Tikal soldiers. Quiriguá's revolution Quiriguá was a small city in the south of the Maya area, it would eventually grow to house 16,000 people. The city had long been a vassal of the larger Copán. In 724 (9.14.12.4.10) Uaxaclajuun Ub'aah K'awiil, Ajaw of Copán, installed K'ak' Tiliw Chan Yopaat as regional ruler of Quiriguá. In 734 at Altar M in Quiriguá, K’ak Tiliw Chan Yopaat gave himself the title k’uhul ajaw, thus declaring Quiriguá’s independence from Copán. This led to a four-year revolutionary war. It was two years later in 736 (9.15.4.7.13) that Wamaw K'awiil and several ambassadors from Calakmul met with K’ak Tiliw Chan Yopaat. On April 27 738 Uaxaclajuun Ub'aah K'awiil was captured by K'ak' Tiliw Chan Yopaat. Due to there having been no major battles around copán or Quiriguá it has been concluded that he was probably not captured in battle. On 3 May 738 (9.15.6.14.6) after a public trial and during a ritual Uaxaclajuun Ub'aah K'awiil was decapitated by an axe thus event is recorded in history as an axe event. After Quiriguá's revolution Though Quiriguá was to a certain extent a vassal of Calakmul it was never directly under Calakmul's control. At the same time Copán never attempted to re conquer Quiriguá because its leaders were afraid of the military power of Calakmul. The alliance was mutually beneficial to Quiriguá and Calakmul. Quiriguá's importance was mainly due to its position on several major trade routes. in 743 El Peru was taken by Tikal and in 744 Naranjo was taken, destroying Calakmuls once
