Last Saturday, the Republic of South Sudan declared its independence, creating the newest nation in the world — the 193rd nation to join the United Nations. The new country has been in the making since a referendum last January, when nearly 4 million southern Sudanese voted to secede from Sudan by a margin of more than 98 percent. The region has been involved in civil wars for at least the past 50 years, and the days-old nation is already battling several armed groups within its new borders. Many issues still remain unresolved — the oil-rich region continues to rely on pipelines that run through Sudan, and a revenue-sharing agreement has not been reached. The new nation, which is comprised of more than 200 ethnic groups, has a largely rural economy, and poverty, civil warfare, and political instability will be the biggest of many challenges for the new administration. Gathered here are scenes from South Sudan as it made its debut on the world stage this weekend.
