Sudan is the largest land in Africa and of the Islamic world. And it is home to one of the oldest civilization of Black Africa; archaeological excavations prove that the area was inhabited at least 60,000 years ago. The currency of Sudan is the Sudanese pound, which was introduced in 1956, when the modern Republic of Sudan was founded. Until 1992, 1 pound held 100 qirsh as well as 1000 millim. Since 1980 millim are not issued anymore, however, as their purchasing power became too small. Today 1 Sudanese pound simply holds 100 qirsh, which are often also called piaster in English.
