The African Union (AU) is a continental organization composed of 55 member states in Africa. It was established in 2002, with the aim of promoting unity, solidarity, and cooperation among African countries. The AU has been instrumental in fostering political and economic integration in Africa, and it has signed several agreements to facilitate this mission.

One of the key agreements signed by the AU is the African Continental Free Trade Area (AfCFTA) agreement. This agreement aims to create a single market for goods and services in Africa, with the goal of boosting intra-African trade and enhancing economic growth. The AfCFTA was signed in March 2018 and came into effect on January 1, 2021. Since then, 54 countries have signed the agreement, making it the largest free trade area in the world by the number of countries involved.

Another important agreement signed by the AU is the Protocol to the Treaty Establishing the African Economic Community Relating to the Pan-African Parliament. The Pan-African Parliament (PAP) is a legislative body of the AU, composed of elected representatives from member states. The PAP was established in 2004 and has the mandate to promote the integration of African countries and their participation in the global economy. The protocol was signed in 2003, and it outlines the functions, powers, and composition of the PAP.

The AU has also signed several agreements related to peace and security on the continent. One such agreement is the African Union Convention on Preventing and Combating Corruption. This convention was adopted in 2003 and provides a framework for African countries to prevent, investigate, and prosecute corruption. The AU has also signed the Protocol Relating to the Establishment of the Peace and Security Council of the African Union, which aims to promote peace and security on the continent. The council is composed of 15 members and has the mandate to prevent, manage, and resolve conflicts in Africa.

In conclusion, the African Union has signed several agreements aimed at promoting unity, solidarity, and cooperation among African countries. These agreements cover a wide range of issues, including trade, governance, peace, and security. The AU continues to play a critical role in fostering political, economic, and social integration in Africa, and these agreements are an important tool in achieving this mission.
