At the epicenter of international boundary treaties, Mesilla, a Mexican-era land colony, became part of the United States in 1854. But different schemes to secede and create a separate territory, along with its temporary use as the Confederate capital of New Mexico during the Civil War, gave this plaza town a much different history and appearance than its contemporaries to the north.
