Sudan is a country located in North Africa, bordered by Egypt to the north, the Red Sea to the northeast, Eritrea and Ethiopia to the east, South Sudan to the south, the Central African Republic to the southwest, Chad to the west, and Libya to the northwest. Sudan has a long and complex history, with ancient civilizations such as the Kingdom of Kush and the Kingdom of Meroe flourishing in the region. Arab traders brought Islam to Sudan in the 7th century, leading to the gradual spread of the religion across the country. British and Egyptian colonial rule began in the 19th century, followed by Sudanese independence in 1956. The country has experienced periods of civil war, including a conflict that led to the secession of South Sudan in 2011. Sudan continues to grapple with political instability and ethnic tensions.
