Disunion Rumblings in Massachusetts
From: bernhard1848@att.net
“In 1843, the legislature of Massachusetts resolved: “That, under no circumstances whatever, can the people of Massachusetts regard the proposition to admit Texas into the Union in any other light than as dangerous to its continuance in peace, in prosperity, and in the enjoyment of those blessings which it is the object of a free government to secure.”
In the year 1844, the legislature “Resolved,…That the project of the annexation of Texas, unless arrested on the threshold, may tend to drive these States into a dissolution of the Union.”
On Washington’s Birthday, in 1845, the Governor of Massachusetts approved a further series of resolutions, from which the following extract is taken:
Resolved,…And, as the powers of legislation, granted in the Constitution of the United States to Congress, do not embrace the admission of a foreign State or foreign territory, by legislation, into the Union, such an act of admission would have no binding force whatever on the people of Massachusetts.”
