The Jews living there rebelled against their Roman reign. Emperor Nero decided that what they did wasn't okay, and he launched an attack against Jerusalem, the Jews' religious stronghold.

Under the ordinance, slavery was forever outlawed from the lands of the Northwest Territory, freedom of religion and other civil liberties were guaranteed, the resident Indians were promised decent treatment, and education was provided for.
