1880 Garret Rock May Day riot
The 1880 Garret Rock May Day riot or 1880 Garret Mountain May Day riot was a civil disorder event in New Jersey that harshly protested oligarchical power. == Riot == For many years Paterson, New Jersey’s mostly Catholic German immigrant community had gathered at Garret Rock, a large plateau at the summit of Garret Mountain in Passaic County, New Jersey, near Paterson in continuation of the ancient German spring festival of "Maying" or ascending a mountain to sing in the rising sun of the first Sunday of May.
