When was the eleventh amendment ratified

The Judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State.

The Eleventh Amendment is a vital element of federal jurisdiction that “go[es] to the very heart of [the] federal system and affect[s] the allocation of power between the United States and the several states.” 1 Footnote
C. Wright , The Law of Federal Courts § 48 at 286 (4th ed. 1983) . It prevents federal courts from construing their judicial power to allow states to be sued by citizens of another state or by foreign states or their citizens or subjects. The Eleventh Amendment was adopted in response to the Supreme Court’s 1793 decision in Chisholm v. Georgia 2 Footnote
Chisholm v. Georgia, 2 U.S. (2 Dall.) 419 (1793) in which the court allowed a suit by a citizen of South Carolina to proceed against the State of Georgia. The Eleventh Amendment resolved uncertainty over the reach of federal judicial power, which had arisen during the Constitution’s ratification.
