In the Abkhazian Autonomous Republic of Georgia, the Abkhazian population, like the Ossetians a distinct ethnic group, feared that the Georgians would eliminate their political autonomy and destroy the Abkhaz as a cultural entity. On one hand, a long history of ill will between the Abkhaz and the Georgians was complicated by the minority status of the Abkhaz within the autonomous republic and by periodic Georgianization campaigns, first by the Soviet and later by the Georgian government. On the other hand, the Georgian majority in Abkhazia resented disproportionate distribution of political and administrative positions to the Abkhaz. Beginning in 1978, Moscow had sought to head off Abkhazian demands for independence by allocating as much as 67 percent of party and government positions to the Abkhaz, although, according to the 1989 census, 2.5 times as many Georgians as Abkhaz lived in Abkhazia.

Tensions in Abkhazia led to open warfare on a much larger scale than in South Ossetia. In July 1992, the Abkhazian Supreme Soviet voted to return to the 1925 constitution under which Abkhazia was separate from Georgia. In August 1992, a force of the Georgian National Guard was sent to the Abkhazian capital of Sukhumi with orders to protect Georgian rail and road supply lines, and to secure the border with Russia. When Abkhazian authorities reacted to this transgression of their selfproclaimed sovereignty, hundreds were killed in fighting between Abkhazian and Georgian forces, and large numbers of refugees fled across the border into Russia or into other parts of Georgia. The Abkhazian government was forced to flee Sukhumi.

For two centuries, the Abkhaz had viewed Russia as a protector of their interests against the Georgians; accordingly, the Georgian incursion of 1992 brought an Abkhazian plea for Russia to intervene and settle the issue. An unknown number of Russian military personnel and volunteers also fought on the side of the Abkhaz, and Shevardnadze accused Yeltsin of intentionally weakening Georgia's national security by supporting separatists. After the failure of three cease-fires, in September 1993 Abkhazian forces besieged and captured Sukhumi and drove the remaining Georgian forces out of Abkhazia. In the fall of 1993, mediation efforts by the United Nations (UN) and Russia were slowed by Georgia's struggle against Gamsakhurdia's forces in Mingrelia, south of Abkhazia. In early 1994, a de facto ceasefire remained in place, with the Inguri River in northwest Georgia serving as the dividing line. Separatist forces made occasional forays into Georgian territory, however.
