number of states (then 11), and became Amendments One through Ten of the Constitution; collectively they are known as the Bill of Rights. On March 4, 1794, in response to the ruling in Chisholm v. Georgia, Congress approved an amendment to the United States Constitution clarifying judicial power over foreign nationals, and limiting the ability of citizens to sue states in federal courts and under federal law, and submitted it to the state legislatures for ratification. The Eleventh Amendment to the United States Constitution was ratified by the requisite number of states (then 12) on February 7, 1795, to become part of the Constitution. Slavery In 1790, the Pennsylvania Abolition Society engaged in an unprecedented lobbying campaign to abolish slavery. Their efforts faced intense opposition from most southern congressmen, who blocked any attempt to abolish an institution that was important to their plantation economy. After a contentious debate, congressional leaders put the proposals aside without voting on them, setting a precedent in which Congress generally avoided discussing slavery. Congress passed two acts related to slavery during the Washington administration: the Fugitive Slave Act of 1793, which made it a federal crime to assist an escaping slave, and established the legal system by which escaped slaves would be returned to their masters; and the Slave Trade Act of 1794, which limited the United States' involvement in the transportation of slaves by prohibiting the export of slaves from the country. Northwest Indian War Following adoption of the Land Ordinance of 1785, American settlers began freely moving west across the Allegheny Mountains and into the Native American-occupied lands beyondland Great Britain had ceded to U.S. control at the end of the Revolutionary War (the Northwest Territory). As they did, they encountered unyielding and often violent resistance from a confederation of tribes. In 1789 (before Washington entered office), an agreement that was supposed to address the grievances of the tribes, the Treaty of Fort Harmar, was signed. This new treaty did almost nothing to stop the rash of violence along the frontier from confrontations between settlers and Native Americans and, the following year, Washington directed the United States Army to enforce U.S. sovereignty. Secretary of War Henry Knox ordered Brigadier General Josiah Harmar to launch a major offensive against the Shawnee and Miami Natives living in the region. In October 1790, his force of 1,453 men was assembled near present-day Fort Wayne, Indiana. Harmar
