Answer:
The 2005 Comprehensive Peace Agreement
Step-by-step explanation:
Although you did not inform the article to which the question refers, we can say that what ended the Civil War in Sudan was the signing of a peace agreement in 2005. This peace agreement ended the war that lasted for almost 20 years and which was characterized as a violent conflict leading to the death of thousands of people.
Sudan's civil war started when the Muslim government in the north of the country tried to impose Islamist policies across the country, including the southern part, where most citizens are Christians.
The conflict was one of the most violent in history and the peace agreement had to be debated for 3 years before it was made official.
