Comprehensive Peace Agreement

A Comprehensive Peace Agreement (CPA) is a type of peace accord designed to resolve the root causes of a conflict in a single, integrated package. Unlike partial accords—such as standalone ceasefires, prisoner exchanges, or humanitarian truces—a CPA typically bundles together provisions on power-sharing, security sector reform, demobilization of armed groups, wealth or resource sharing, transitional justice, refugee return, and a roadmap for elections or constitutional change.

The term became widely used after the 2005 Comprehensive Peace Agreement signed in Nairobi between the Government of Sudan and the Sudan People's Liberation Movement/Army (SPLM/A), which ended the second Sudanese civil war and created the framework for South Sudan's 2011 independence referendum. Earlier accords with similar scope include the 1996 Guatemalan Peace Accords between the government and the URNG, often cited as a model "comprehensive" settlement.

Typical structural features include:

• Sequenced implementation timetables, often spanning 5–10 years
• Third-party guarantors or witnesses (states, the UN, regional bodies such as IGAD, ECOWAS, or the AU)
• Monitoring and verification mechanisms, frequently a UN peacekeeping or political mission
• Interim governance arrangements pending final-status elections
• Linkage clauses binding the parties to treat the agreement as a single, indivisible package

Researchers at institutions such as the Kroc Institute and Uppsala Conflict Data Program track CPAs because their multi-issue scope makes implementation rates a useful indicator of durable peace. Empirical literature, including work by Caroline Hartzell and Matthew Hoddie, generally finds that agreements covering political, military, territorial, and economic dimensions are more durable than narrower ones, though implementation gaps remain common. CPAs can also fail spectacularly when key provisions stall—as seen in the renewed fighting in South Sudan after 2013, despite the 2005 framework.
