Tribe Dissolve

A Tribe Dissolve occurs when one or two tribes are dissolved before the merge and either its members are absorbed into the other tribes, or the remaining castaways shuffled into the remaining tribes. It is a special variant of the Tribe Switch.

Types of Tribe Dissolve
There are currently three main types of tribal dissolution:
 * Disbanded and shuffled - where one or two tribes ceased to exist where all remaining players still in the game (regardless of tribal affiliation) are shuffled into the remaining tribes. Seen in, and
 * Absorbed - a type of dissolve where a tribe's remaining members are scattered between the other remaining tribes, were the members of the undissolved tribes stay there. Seen in, and.
 * Conquered - a type of absorption where the remaining members of the losing tribe go directly to the other tribe, where the season has no Merge. Seen in.

Survivor: Pearl Islands
The first time a dissolve happened was directly after The Outcasts' Tribal Council, when Burton Roberts and Lillian Morris were voted back into the game. After the Tribal Council, the Outcasts Tribe was removed from play.

Type: Absorbed

Survivor: All-Stars
The second time a dissolve happened was during Day 13 of Survivor: All-Stars, where the tribes were told that the tribe that finishes last at the Reward Challenge would cease to exist and their remaining members will be absorbed by the other two tribes, the Saboga tribe finished last and was subsequently dissolved into Mogo Mogo and Chapera.

Type: Absorbed

Survivor: Palau
A special case caused Survivor: Palau to have a Tribe Absorption while only having two competing tribes. This was when one of the tribes, Ulong, was down to its last member, who simply joined the other tribe, Koror. There was no Merge that season, as Koror remained to exist until the final day of the competition.

Type: Conquered

Survivor: Panama
The first tribe disbandment occurred in Survivor: Panama, which had four tribes. The Bayoneta and Viveros tribes were disbanded, then all but one of the remaining castaways were spread into the two remaining tribes (Casaya and La Mina), arranged via a Schoolyard Pick. The castaway not chosen was sent to Exile Island, in which that castaway would be assigned to the tribe that would eliminate a castaway in the next Tribal Council.

Type: Disbanded

Survivor: Cook Islands
A tribe disbandment occurred in Survivor: Cook Islands, which had four tribes. Similar to Panama, the Manihiki and Puka Puka tribes were disbanded, and all of the remaining castaways are spread into the remaining Aitutaki and Rarotonga tribes via Schoolyard Pick. Unlike in Panama, there were an even number of castaways remaining, so no one was exiled.

Type: Disbanded

Survivor: Philippines
In Survivor: Philippines, which had three tribes, The Matsing tribe was quickly dwindled down to two members, Malcolm Freberg and Denise Stapley and was subsequently absorbed. The last two members were absorbed by the other two tribes, with Malcolm joining Tandang and Denise joining Kalabaw. This absorption is similar to the absorption in All-Stars, where it took place at the final 14 and the dissolved tribe's members are split up into the remaining tribes.

Type: Absorbed

Survivor: Cagayan
In, which originally had a three-tribe theme of Brawn vs Brains vs Beauty, a tribal disbandment occurred. At Day 12, right before the Reward Challenge, the Luzon tribe was disbanded, and each of the castaways gets buff that is covered up. Based on the buff, they would be put to either Aparri or Solana. Type: Disbanded
