A declaration of the causes
which impel the State of Texas to secede
from the Federal Union
The government of the United States, by certain joint resolutions, bearing date the 1st day of March, in the year A. D. 1845, proposed to the Republic of Texas, then a free, sovereign and independent nation, the annexation of the latter to the former, as one of the co-equal States thereof,
The people of Texas, by deputies in convention assembled, on the fourth day of July of the same year, assented to and accepted said proposals and formed a constitution for the proposed State, upon which on the 29th day of December in the same year, said State was formally admitted into the Confederated Union.
Texas abandoned her separate national existence and consented to become one of the Confederated States to promote her welfare, insure domestic tranquillity and secure more substantially the blessings of peace and liberty to her people. She was received into the confederacy with her own constitution under the guarantee of the federal constitution and the compact of annexation, that she should enjoy these blessings. She was received as a commonwealth holding, maintaining and protecting the institution known as negro slavery--the servitude of the African to the white race within her limits--a relation that had existed from the first settlement of her wilderness by the white race, and which her people intended should exist in all future time. Her institutions and geographical position established the strongest ties between her and other slave-holding States of the confederacy. Those ties have been strengthened by association. But what has been the course of the government of the United States, and of the people and authorities of the non-slave-holding States, since our connection with them?
The controlling majority of the Federal Government, under various pretenses and disguises, has so administered the same as to exclude the citizens of the Southern States, unless under odious and unconstitutional restrictions, from all the immense territory owned in common by all the States on the Pacific Ocean, for the avowed purpose of acquiring sufficient power in the common government to use it as a means of destroying the institutions of Texas and her sister slave-holding States.
By the disloyalty of the Northern States and their citizens and the imbecility of the Federal Government, infamous combinations of incendiaries and outlaws have been permitted in those States and the common territory of Kansas to trample upon the federal laws, to war upon the lives and property of Southern citizens in that territory, and finally, by violence and mob law to usurp the possession of the same as exclusively the property of the Northern States.
The Federal Government, while but partially under the control of these our unnatural and sectional enemies, has for years almost entirely failed to protect the lives and property of the people of Texas against the Indian savages on our border, and more recently against the murderous forays of banditti from the neighboring territory of Mexico; and when our State government has expended large amounts for such purpose, the Federal Government has refused reimbursement therefor, thus rendering our condition more insecure and harassing than it was during the existence of the Republic of Texas.
These and other wrongs we have patiently borne in the vain hope that a returning sense of justice and humanity would induce a different course of administration. "
These are a few of the reasons why Texas seceeded. The word "Slavery" is only mentioned twice if i am not mistaken.
