Problem: The earliest dynastic king on the Sumerian king list whose name is known from any other legendary source is Etana, 13th king of the first dynasty of Kish. The earliest king authenticated through archaeological evidence is Enmebaragesi of Kish (c. 26th century BC), whose name is also mentioned in the Gilgamesh epic—leading to the suggestion that Gilgamesh himself might have been a historical king of Uruk. As the Epic of Gilgamesh shows, this period was associated with increased war. Cities became walled, and increased in size as undefended villages in southern Mesopotamia disappeared. (Gilgamesh is credited with having built the walls of Uruk).
Who is the earliest king that is authenticated by actual physical evidence and not just legend?
The answer is the following: Enmebaragesi

Problem: In Lemon v. Kurtzman, 403 U.S. 602 (1971), the court determined that a Pennsylvania state policy of reimbursing the salaries and related costs of teachers of secular subjects in private religious schools violated the Establishment Clause. The court's decision argued that the separation of church and state could never be absolute: "Our prior holdings do not call for total separation between church and state; total separation is not possible in an absolute sense. Some relationship between government and religious organizations is inevitable," the court wrote. "Judicial caveats against entanglement must recognize that the line of separation, far from being a "wall," is a blurred, indistinct, and variable barrier depending on all the circumstances of a particular relationship."
What did the state's policy violate?
The answer is the following:
the Establishment Clause
