1877 Twenty-six were killed and many wounded in the “Battle of 28th Street,” which started when militiamen from Philadelphia fired on strikers.

1925 The so-called “Monkey Trial” ended in Dayton, Tenn., with John T. Scopes found guilty of violating state law for teaching Darwin’s Theory of Evolution. (The conviction was later overturned on a technicality.)

1959 A steel strike slowed down construction of the Civic Arena.

1972 The Irish Republican Army carried out 22 bombings in Belfast, Northern Ireland, killing nine people and injuring 130 in what became known as “Bloody Friday.”

1999 A drought emergency was declared in 55 counties in Pennsylvania.

2020 The Republican speaker of the Ohio House, Larry Householder, and four associates were arrested in a $60 million federal bribery case connected to a taxpayer-funded bailout of Ohio’s two nuclear power plants. (Householder, who has proclaimed his innocence, was expelled from the Ohio House by fellow lawmakers in June 2021.)
