Republic of Texas The Sovereign Nation, Land and Government
None of the land has ever been ceded to the United States, so there is no need to secceed. The Federal Government owns the land for the other 49 states. But for Texas they can only lease portions of land they want to occupy within Texas. Leases are conditional and don't have to be renewed. Most of these have to be renewed every year or so.
