What did the Texas constitution do?

The Constitution of 1876 is the sixth constitution by which Texas has been governed since independence from Mexico was achieved in 1836. It was framed by the Constitutional Convention of 1875 and adopted on February 15, 1876, by a vote of 136,606 to 56,652, and it remains the basic organic law of Texas. Jun 12, 2010

It declared that Texas was a free and independent state, subject only to the Constitution of the United States, that all free men have equal rights, and that the writ of habeas corpus could not be suspended or unduly delayed. It has our bill of rights.
