The rivers converge at what is the southernmost point in Illinois at Fort Defiance State Park, an American Civil War fort that was commanded by General Ulysses S. Grant, making Cairo the only city in Illinois completely surrounded by levees. It is part of the Cape Girardeau–Jackson, MO-IL Metropolitan Statistical Area. Several blocks in the town comprise the Cairo Historic District, listed on the National Register of Historic Places (NRHP). The Old Customhouse is also on the NRHP.

What is international law?

Private International law (or conflict of laws) is a set of rules of procedural law which determine which legal system and the law of which jurisdiction apply to a given legal dispute. They typically apply when a legal dispute has a foreign element such as a contract agreed by parties located in different countries. Private International Law attorneys represent clients in legal disputes involving citizens and businesses in other countries.

Attorneys who practice Public International Law handle cases involving legal and practical relationships between nations -- including issues like agreements and treaties between nations, international trade regulation, and human rights.
