In 537 the Ajaws of Bonampak, Lakamtuun, and Calakmul were captured by Yaxchilan. Bonampak and Lakamtuun remained under the control of Yaxchilan but in retaliation Calakmul conquered the latter. This gave the polity a adventagous strategic position with territory in both the east and the west of Tikal. In numerical terms, however, Calakmul remained inferior to Tikal: Despite being one of the most prosperous Maya cities, Calakmul housed just about 50,000 people, while its entire kingdom had a population of 200,000. In contrast, Tikal was home to almost half a million people. Both city states greatly eclipsed other Mayan polities, and have been described as "superpowers" that led rival power blocs.
First war, 537–572
After conquering Yaxchilan and its subsidiaries, Calakmul allied itself with anti-Tikal cities such as Caracol, El Perú and El Zotz. The latter in particular was located closely to Tikal, and had been opposed to its more powerful neighbor for a long time. The conflict between Tikal, Calakmul and their respective allies resulted in the increasing sophistication of Maya warfare, including the construction of large, well-fortified citadels to protect strategically significant routes. One of the most notable forts, La Cuernavilla, was constructed between Tikal and El Zotz. Calakmul went on to conquer Naranjo in 546. Tikal and its kingdom were not destroyed, but suffered major losses and went into decline after the war ended in 572.
"Cold War"
The phrase cold war has been used to describe the time between major conflicts involving Calakmul and Tikal. During these times there was continuous war but no major battles or political changes took place. There were of course minor border skirmishes. As Tikal gradually regained strength, its local, smaller rivals such as El Zotz declined.
Second war, 650–695
The second war lasted from 650 to 695. One of the main battle grounds of this conflict was Dos Pilas, a city which had been established as military outpost by Tikal. Ruled by B'alaj Chan K'awiil, the brother of Tikal's king, Dos Pilas was overrun by Calakmul after years of heavy combat. B'alaj Chan K'awiil initially fled into exile, but then opted to switch sides and restored his rule of Dos Pilas, this time under Calakmul's dominance. Supported by his new allies, Dos Pilas consequently began a destructive "proxy war" against its old mother city. B'alaj Chan K'awiil laid claim to the royal titleAjaw and emblem of Tikal. He won the war with Tikal, captured and sacrificed the city's ruler. From then until 695, three years after B'alaj's death, Calakmul factually dominated Tikal. In 695, under the leadership of Jasaw Chan K'awiil I, Tikal won a major battle with Calakmul and turned the tables, effectively ending the Second Tikal–Calakmul War.
Third war, 720–744
, Ajaw of Quiriguá was one of the key people during the third war. Quiriguá was a province of Copán, then in 734 K'ak' Tiliw Chan Yopaat lead a revolution against Uaxaclajuun Ub'aah K'awiil, Ajaw of Copán. Wamaw K'awiil, kaloomte of Calakmul traveled to Quiriguá and formed an alliance with K'ak' Tiliw Chan Yopaat. Uaxaclajuun Ub'aah K'awiil was executed in 738, and Quiriguá became independent. By 744 El Peru and Naranjo had been reconquered by Tikal, and Calakmul had been defeated.
Aftermath
Having been deprived of its military reputation Calakmul lost its northern provinces and collapsed, the last recorded date in the city was 899, possibly 909. Similarly Tikal, and most of the Maya cities were destroyed in the Maya collapse. The war may have contributed to the collapse, along with overpopulation, disease, famine, and others.
