On this day 250 years ago in Massachusetts, Royal Governor and General Thomas Gage issued a proclamation declaring the Solemn League and Covenant “unlawful”, “scandalous, traiterous, and seditious” and that those signing the Covenant were “the declared and open Enemies of the King, Parliament, and Kingdom of Great Britain.” Accordingly, Gage ordered the arrest of anyone who signed the Covenant, and anyone “aiding, abetting, advising or assisting” distribution of the Covenant.
