Texas secession movements: Texas secession movements principally focus on the secession of Texas during the American Civil War and the activities of organizations that have existed since the 1990s.  The United States Constitution does not address secession of states and the issue was a topic of debate from after the Revolutionary War up until the Civil War, when the Supreme Court ruled, in "Texas v. White," that states cannot secede.  Texas claimed to be a sovereign state for nine years prior to the negotiated annexation with the United States, but its claim was not recognized by Mexico, nor did Texas actually control the entirety of its claimed territory.  This history has affected the state's politics ever since, including its standing in the Confederacy in the Civil War to education and even tourism in the 20th century.  Modern secession efforts have existed in the state at least since the 1990s, focusing first on the Republic of Texas organization founded by Richard Lance McLaren and later on the Texas Nationalist Movement headed by Daniel Miller.
