The Austin-Washington Letters were a set of letters between Texan President (INH) and US President (INH) discussing the ways to limit the expansion of slavery in Texas. They wanted Texas to be able to help the US if the South seceded.
Effects of the Letters
There were several effects of these letters. Because of them, the Immigration Limit Act was passed in Texas, limiting the amount of Slave owning immigrants moving into Texas. However, the most noticable effect was that when these letters were leaked out by a Southern Sympathizer, the South and Slave owning parts of Texas seceded. This began the American Civil Wars and caused the deaths of thousands of Americans and Texans.
